I have found the throttle response on my new E-TEC 150 to be a bit switch-like. I cannot graduate the motor through a smooth speed change. At three distinct points the RPM's jump. Most notable was at 2,000-RPM. Any advancement no matter how gradual causes the motor to lurch from 2,000-RPM to 2,400-RPM. (My wife and kids easily lose balance when this happens and I find it to be unsafe). It also jumped at two other points but I was unable to see the tachometer as it is flush mounted and I was standing up due to the choppy water. This was noted in another thread but I thought it would get more visibility here in its own thread. A software revision was mentioned by Seahorse in the other thread. I need more info on this so that I may speak with the dealer in regard to it. |

Yours might be one of the earlier ones that had the old style throttle cam. Your dealer can order the newer cam under warranty, it is the same part number as is in the "parts book". Have him install the latest software version also. This is all warranty. |

[BLACK MAX is one of LHG's alternate identities. Here he throws out some provocative claims and exaggerations as part of his general campaign against the Evinrude engines--jimh] Let me see if I got this right. This engine is introduced in Miami 16 months ago as the best thing since sliced bread. After several false "they're being shipped" notices on various websites, Now the BRP insiders are telling him he got one of the "earlier ones" with the "old style throttle cam" and old software, on this brand new, just produced, engine that he waited for for 5 months! This sounds more like a work in progress, complete with test dummies, rather than a finished work. And the BRP dealer doesn't return calls. Having any "I shoulda bought a DTS 4-stroke Verado" nightmares? |

If you look at almost any outboard engine, you will see that the motion of the remote throttle lever is a push-pull movement of an actuator cable. This is almost universally connected to a lever arrangement which contains a cam shape. The movement of this cam-shaped lever actuates the actual throttle linkage, usually via a roller which rides on the cam. Usually the cam shape of the connecting lever is designed in a fortuitous manner so that the operation of the remote throttle lever--which itself is linked to the cable via a cam shape of its own--produces an agreeable rate of change in engine power with change in throttle position. It sounds like Bombardier engineers have made a small change in the cam shape of the lever in the throttle linkage so as to improve the feel of the remote throttle actuator. The remote throttle actuator may be used with all sorts of engines, and it may be necessary to adjust the rate of change of movement produced by the remote throttle--which is common to all engines in the brand--so that it works better with a particular engine. All we are talking about here is replacing a plastic lever under the cowling in the throttle linkage. It is not like we have to put an all new power head on the engine, replace the entire fuel rail distribution system, or replace all the injectors. It's just a minor change in the shape of a piece of plastic. And coupled with some firmware updates it makes the feel of the remote throttle better with this particular model. Now if the entire throttle system were an electro-servo arrangement linked to the remote control via a digital data bus, it would be possible to tweak all of this in software and firmware. However, one big advantage to a mechanical throttle linkage is that it never needs a battery to operate. So if your boat electrical system goes out, a mechanical throttle system will still work, while a complex electro-mechanical throttle system may become unusable. |

I was giving the throttle lever linkage some more thought. It is a complicated arrangement. On the remote control throttle handle, the control usually moves through about a 90-degree arc, but there is quite a bit of dead-band in that movement for the shift from neutral to forward. The actual portion of the arc in the remote throttle lever which moves the throttle cable may only be about 60-degrees or less. This movement is translated to a linear movement of the throttle cable. That linear movement is mechanically conveyed to the engine, and there it operates another lever in the linkage. The lever in the linkage connected to the remote throttle is usually designed in such a way that the linear motion is translated back to an angular rotation of the engine's throttle control shaft. The engine throttle shaft may require a range of rotation of 90-degrees, that is, to be able to open the throttle plate fully from a closed position. The linkage has to convert the linear motion of the actuator cable into a angular rotation of the throttle. This is where there can be some adjustment of the couple so that the rate of change of the remote throttle and the rate of change of the actual throttle plate. The coupling does not have to be entirely linear. By using a cam shape, the engine designers can adjust the rate of coupling so that the remote throttle lever movement has better feel. It may be that a particular engine may have much faster throttle response than most operators are accustomed to, and in order to make the remote control have a better feel, the rate of change in actual throttle movement might have to be varied in certain portions of the throttle range. In doing so it will give the operator more control. I have run many motors where the remote throttle controls do not have much engineering built into them, and you can push the throttle forward quite a bit without much engine response. Then a threshold is reached and the engine response becomes very rapid, giving the throttle a very sensitive and hard to control feel. A general reaction reported by most people operating an E-TEC is surprise at the extremely strong engine pull or torque as the engine spools up to higher engine speeds. Operators may not be accustomed to getting such strong response from their engine in these lower engine speed ranges. This may have creating some problems when operating this particular engine. It sounds like the Bombardier engineers have worked out an improvement by changing the throttle linkage and the firmware. |

seahorse suggested I contact customer service with my serial number. I'll do that on Monday and report back what I learn from the conversation. It expressly states in the owner's manual that one MUST NOT move the throttle/shift lever when the motor is off. Why? I do not know.... I assumed it must have something to do with the computer and it knowing "home" position. Just an uneducated guess. Due to this warning, I am reluctant to take the cover off and view the movement of the throttle. seahorse, thanks! |

posted 06-24-2006 08:52 AM ET (US)
The not moving the throttle lever when the motor is off applies to ALL makes of outboards. If one of the gears and clutch dog are not lined up inside the gearcase, a person could push or pull very hard on the control box lever and bend or damage something, stress the control cable, and maybe affect the linkage on the motor. When an ouboard is running, the gears are rotating and the clutch dog will then "fall in place" when shifting. If you do have to shift into gear when the motor is not running, have someone spinning the prop while you shift it into gear. |

Wouldn't that be similar to the 2 year late Verado being delivered to customers and then finding out that the original motor covers and cowlings allowed saltwater to get into the enignes and sometimes damaging the supercharger? Like all companies when introducing a new product and things show up, Merc got busy and redesigned the cowlings and got them out to the owners of the early models.

I think Larry should be more worried about his own company's situation than about a minor cam adjustment to the E-TEC 150. Right now, Mercury has no quiet 150 HP outboard product that weighs less than 500 lbs to sell, much less make minor adjustments on! Not a good situation to be in if your company's tag line is "#1 on the water". Jay -- I think some of your difficulty might be with not having enough pitch on the propeller to load up the engine. Also, the throttle response of a DFI engine is different than the carbureted version. I have found that the DFI is much more responsive to throttle input. |
JayR |
posted 06-24-2006 11:10 AM ET (US)
Peter, it is certainly not a propeller issue. The throttle acts like a switch at the 2000 rpm range. No matter how gradual it advance it, nothing changes until I get to a specific point and the motor JUMPS 400 rpm's. It does this again above 3000 rpm's and again above 4000 rpm's. I can't tell you exactly the range on the higher two points as my tach is dash mounted and I was having to stand to operate the boat. The water was quite rough and I could not watch the tach and navigate safely. This hull weighs less than 1500 pounds, the prop is a 14.8 x 17 and WOT results in an RPM of 5700. 5750 RPM's is the max..... |

OK. I don't know whether the mapping and exhaust tuning is the same as on the Ficht but there may be a zone or two where the motor just won't settle in. For me, its between 4000 and 4200 RPM. Slight throttle advance or retard will take it from 4000 to 4200 or back to 4000. I think this is a zone where fuel mapping and exhaust tuning transitions come into play. It seems alot like the 4400 RPM range on the Yamaha 70 2-stroke where there is an exhaust tuning harmonic transition going on. |

This picture (see link below) shows the link lever between the incoming throttle cable and the throttle plate link on an E-TEC. You can see the cam-like shape of the lever and the roller than bears against it. This is what we are discussing: the particular curve of this piece of plastic.

It finally stopped pouring here long enough for a look see under the cowl of my 150. I was surprised to see a much different shape to the cam on my motor compared to the one depicted in Jimh's photo. Different size motor I would assume. http://img75.imageshack.us/img75/3155/062420060260gn.jpg Advancing the throttle to the approximate position where I encountered the jump puts the cam at a contact point where there is a large change in degree on the cam. I can see where this may very well be the issue. |

I believe that Jim's picture is of the 3.3L 90 degree 225 not the 2.6L 60 degree 150. If I'm correct, we are comparing apples to oranges here. |

The engine in my picture is a 3.3-L E-TEC. I didn't mean to confuse, but to demonstrate how the linkage lever has a curve and cam. And, yes, there is quite a difference between the two models of E-TEC. |
JayR |
posted 06-25-2006 10:04 AM ET (US)
When I looked at the locations of the other components on the motor, it was obvious they motors are not the same. I still find the differences quite substantial and I am left to wonder why there is such a difference as one would expect the mechanical aspect of moving the throttle to be similar among all the motors. |

I spoke with Evinrude Customer Service this morning... No help whatsoever!!!! I was informed that my dealer would have to speak with the people in technical service and that I could not. He did say there was a software revision but had no info on a cam update. It was the first he had heard of it..... |
seahorse |
posted 06-26-2006 07:02 PM ET (US)
The customer service folks do not discuss technical details with customers, that is for your dealer tech to discuss with the dealer tech "hot line". At least your serial number, complaint, and conversation notes are on record with the company. that is the important thing. Talk to your tech and explain what was suggested and ask him to talk to the factory techs about it. Be sure to read my "cam" post in the other forum. |

As we all know Larry(BlackMax) has to chime in once in awhile so he can knock the ETEC. He never admits that his beloved Verado has also had some problems just like every product made by man. For instance he would never tell you that the Verado has had several problems with the fuel pump and is undergoing a recall at this time. Give it a rest Larry, everyone knows it's you! |

Boat is getting dropped off at the dealer on Monday for the cam upgrade and I-Command gauges install. Cam issue effects 175 HP E-TEC as well... If you try to order a replacement, you will get the old model. The only way my dealer claims to have been able to get the new one was through the factory production line. Hope that is helpful to some of you. I know I'll be happy to remedy this problem. |

Dropped it off this morning for the upgrade to the cam, software and to replace the systemsCheck tach with the I-Command. Dealer claims just a small number of motors were shipped with this cam issue. Somehow, I doubt it were just a few as I have heard of others with the issue as well. Wonder how many of the 150 and 175 need this upgrade? I'll report back on how well it remedies the problem as soon as I have it back on the water. |

I was happy to get a good price on this motor but you can darn well bet I'm going to find another dealer to work on it.... I dropped it off on Monday per their request. The replacement cam and the I-Command stuff was to be there Monday or Tuesday. Here it is Friday and I had to email, voice-mail (still no response)and then call again to find out the status. Dealer did not order all the necessary components for the I-Command and I'm stuck waiting still. The additional cables the ordered will not be in until Monday or Tuesday. Arghhhhhh!!!!!!! They offered to get it to me today with the new cam installed but I would have to bring it back again next week. Considering it is a 2 + hour ride there and back, I passed. Can't afford to drive 5 hours time just to have the boat for a couple days. I need a closer more reliable dealer!!!!! |

Eighteen days.... That's how long it took them to figure it all out, receive the correct components and get the I-Command installed... Hard to believe! Trailered it home this afternoon. I was supposed to get a call earlier today informining me as to when it could be picked up. I did not so at 2:00 I drove over to the marina and waited for it to be completed. I half expected to see it still incomplete. I planned on pulling it home even if that were the case. Now to find another service center.... Pics to follow. They did a clean job and hopefully the new cam is in there too. Lightning here at the moment... |

It's like getting blood from a stone.... I e-mail and call and most often do not get a response from either. I am not going to return to that marina for ANYTHING!!!!!! Very disappointed with their service and customer relations. Even the woman who answers the phone has the phone etiquette of a 5 year old. She has on many occasions hung up without even a "bye". I don't trust them to do anything correct and I would like to ensure they upgraded the software as they said they did. Due to a conversation when I picked up the boat, I suspect they didn't. When I picked up the boat, the old wiring harness was on the floor under foot and under the roll around tool bow. The systems check tach was neatly secured away in a box in the mechanics tool chest. When I arrived at the boat yard, it was still in the boat on the console. When I returned from a trip to my truck to check on my sons it was gone as was the mechanic. I had to search the area to find it. Mechanic looked awful disappointed when he found me with it in my hand. I'm not going back, not calling them and I'll go elsewhere for my service. |
