RPM MPH MPG
600 3.5 35
3500 30 9.7
4100 35 8.6
4400 40 7.9
4800 45 7.3

I am very pleased. Plus the quietness and smooth power. The motor looks smaller than the 70 Mercury. Boat floats abot the same too.

Thanks in past for all the info on this site;o)

With your extensive propeller knowledge, how would you compare the Raker 20" and Stiletto 13-1/4" x 19" Advantage I to the SST II 21"?

posted 04-21-2008 05:47 PM ET (US)            

In this thread Len reports 5150 RPM at 47 MPH, so I think the 19" Advantage I is the ticket, not the 17".

Len,

I have no personal experience with the Raker, but I think you should try it to see what happens. I am curious.

Rob and I have both donated props for testing on both his E-TEC 90 powered Montauk and a 15 foot Whaler with a 75 HP E-TEC. The props were a 15" Advantage I and a 17" OMC SST. The RPMs were very comparable even with the two inch discrepancy in nominal pitch, this is why I think the 19" Advantage I will work for you.

There is no question but the Stiletto will tolerate a higher mounting height and grip better. It may not be much faster than your SST as rigged now, but if you can dial in you're mounting height (read: raise the motor), the Advantage I will be happier, you will have less drag and more speed. The SST will not work with higher mounting heights; it will simply start to ventilate.

I do have a 22" Laser II I was running with the 70hp Mercury I could get a hub kit but the hub itself would have to be modified it is too large by ~1/8" diameter, maybe I'll do that, I do have access to a lathe. Remember though, that gear ratio is different 2.33/1 on the Mercury vs 2.0/1 on the E-TEC.

I am raising the motor on the hydraulic jack plate as right now I can run it all the way up without loosing water pressure, I am probably going to highest mounting height in the lowest hole hole on the motor. Right now it is mounted one hole down on the motor I have two more to go which is 1 1/2" higher. This will allow me to run in shallower water, at least at idle.

Thanks for the comment on the looks, everyone who has seen it in person thinks it looks like a better fit than the Mercury...smaller.

Do you guys want to go up against a 20" Renegade? I found one of those and should have it next week. Still looking for the Raker also, I will find one soon.

My I-Command gauge will make the comparison easy. Do we need a independent judge I think the Judge will be available. I have only two days of work next week, Monday and Tuesday. Are you up for the job Nick?

How would you compare the OMC props? Benefits or strong points of each?

posted 04-23-2008 09:45 PM ET (US)            

I have three more props on the way:
19" Stilletto, Tom Clark
20" Renegade,lightly used eBay
22" Raker, new Ebay
plus the 21" SST II I already had

I also put the engine on the computer today and changed it over to run XD100 oil which I put in from the start. The E-TEC system software works very well on my PDA (Garmin iQ3600) and I printed a report.

I was going to post something snide, but in searching the internet for some way to type an emoticon representing a chicken making clucking sounds, I came up empty.

Remember, the older props are using the rubber hub sedign while the newer ones are using the TBx core design. Also on thenew Raker II theres 5/8" vent holes while the older rakers had , I believe 1/4 " vnetes.

Just here to help.... sort of

Dont be afraid to play with the motor height, I was able to run my Raker a lot higher than I could my previous prop.

Will probably run out of water at the intake though so any ideas on a prop with less bow lift characterists? I'm not sure how to get there

I am off to Italy tomorrow so will not have boat in water untill next Sunday, what are you doing?

Of course, northern Italy, Going to Lake Garda for a few days though, that will be a nice deviation from the usual German/Italian Alpine cuisine to some real dining pleasure. The Valpolicella vineyards are nice to eat at. The Verona area, which includes Lago di Garda has some of the best food and wines.

Did you get the e-mail about Pierce? Do you use their trucks?

Margit says hi to the SC guys.

3) Yeah...what gives on those performance figures????

4) Notice the ;) in the first paragraph???

Here is some data that has been collected today. Conditions were ~80º air and ~80º water, cross wind of 15-20 mph carrying 9 gallons of fuel, 50 lbs of lead (in anchor locker, mistakenly not removed) and two passengers weighing 260 total.

The engine was not moved vertically during the test. Only trim was adjusted over 4000 rpm.

The variabilities within the adjustments available with hydraulic trim are difficult to keep up with. Driving this boat at speed is not a leisurely activity when trying to hold certain rpms and take notes. I must give credit to wife Margit for data collection and the graphing.

Opinions as always please.

Once again we see that the OMC SST design is an excellent one. In this case the 21" SST and the 19" Stiletto Advantage I perform very nearly the same (and is also why you often see me recommending the Advantage in pitches of about two inches less than what most people expect).

However, once you start raising your motor you will quickly realize that the SST will start to ventilate and loose grip while the Stiletto Advantage I will hold on and become even faster. That is the big difference between them.

I have not even accurately recorded my F60 since the Garmin 545s, but plan to this weekend minus PITA, the old PATE with about 4 gallons of emergeny fuel, and an old OMC 6 gallon rolling around aft. My new aluminum custom tank came in at 19 gallons, under rear thwart, and primed. Don't even want to tell you the price, same company as my 20 gal. in the skiff, 5 years ago...Holy Crap!

Stilletto ran 52.2 tonight @5600rpm. It was just me on the boat without the 50 lbs of lead up front.

I need to raise the engine more to cut back on the bow lift caused by trimming the motor out to get the revs. Another couple of inches higher will get the revs and keep the boat more level, I think.

posted 06-11-2008 09:27 AM ET (US)            

Wow! Yes, raise that motor but I think you may have a problem with the prop. You are already above the redline and will only gain more once the motor is raised.

The E-TEC 90 redlines at 5500 RPM but is actually happy if propped a bit lower. The factory recommends this for the E-TEC 90:

Recommended WOT Range - 4500-5500

Optimum WOT Range -- 5000-5200

Incredible as it may sound, I think you should try the 21" Stiletto Advantage I

This rig looked pretty, was set up as a super sport, and he said the prop was a 26 inch pitch. No bracket, but the motor was up about three holes. Bottom paint. And he crowed that he loved to run out on the flats along with all the speed boats with his crab net and fishing poles flying in the rod holders.

I wish I had a camera for you folks.
