Author Topic:   1973 Outrage 19 Re-power with E-TEC 115

showtime35 posted 04-11-2008 10:21 PM ET (US)
I will soon be re-powering my 1973 Boston Whaler Outrage 19. Does an Evinrude E-TEC 115 have enough power for this Outrage? Normally there will be three guys in the boat and each one weighing 250-lbs. The boat weighs 1,500-lbs and has a 40-gallon fuel tank. I had a 1997 Montauk with a 90 E-TEC on the back, and it had plenty of power. Please everybody feel free for opinions; I could use them. I am concerned about the weight of four-cycle motors. The new four-cycle motors are not really designed for the older boats, and I want to keep the weight down. The older boats are really designed for two-cycle motors. Everybody's help would be most appreciated.
Thanks to all.

The Evinrude E-TEC 115 V4 is an interesting engine. It seems to be the sleeper engine in the E-TEC line. The dock talk about the E-TEC 115 is that it has enough power that it preempted the introduction of a 130-HP based on the same block. I guess that is to say the rumor about the E-TEC 115-HP is that it is a strong engine for its power rating.
The horsepower to weight ratio of the four-cycle outboard motors has been improving, but the E-TEC still tends to be lighter.
The older Boston Whaler OUTRAGE hulls like your seem to be tolerant of weight on the transom, so I would not let that concern completely rule out the option of a four-cycle motor.
115-HP Motor Comparison
Evinrude E-TEC 115 = 375-lbs
Mercury 115 FOURSTROKE = 386-lbs
A difference of 11-lbs is not significant. You really cannot use the weight as means to dismiss the option of a four-cycle motor for your re-power.

We have a 2007 115 etec mounted on a 18ft hurricane deck boat. The model is a 198 Re. Its the twenty inch shaft version. The boat I believe weighs in around 2250 pounds dry. Currently we have about 160 hours of use on this combination in one summer and the motor is just absolutly flawless. Quiet, smooth runnig, power, torque, great economy. I have had the boat at 41 mph speedo with just me, and i routinly have 6 to 7 people in there with two coolers full of beer and will still hit 37-38. Pulls skiers up no prob even with that load. running a 13-1/2 x 15 brp aluminum prop. thinking of going going with a stainless this summer. we had it out the first time about 2 weeks ago after the winter storage and it started instantly. this motor never misses a beat and is perfect for our lake as it has a max hp of 115. we love it

It will be plenty of motor for that hull.

I have a 115 Suzuki @ 420lbs and honestly it is NOT enough weight on the transom of my 19 revenge which is one bow heavy boat. The 115 will be a great engine and expect about 40mph top end and a 25+mph cruise that will yield about 5-6mpg. perfect considering we only have a 40 gal tank. If you can get a better deal on a 4s and want one, don't worry at ALL about the weight. After driving a few e-tecs recently, my Suzuki is much quieter than they are and that is a fact.
JayR posted 04-15-2008 05:46 PM ET (US)
Yes, those Suzukis are very quiet. However, I would not call the E-TEC loud.

I repowered my 1971 Outrae with a Suzuki DF150 a year ago. Pic's of the repower are here:
http://s28.photobucket.com/albums/c210/JohnPW/repower/
An older thread on the repower is here:
http://continuouswave.com/ubb/Forum4/HTML/005197.html
I am still very pleased with the repower. I top out around 46 mph with a full load using a 4 blade prop that is not designed for top speed. The weight has not been a problem at all, although it is a couple inches lower in the stern at rest than it was with the 2 stroke Johnson 150 it replaced (see the pic's). The boat gets great gas mileasge, and the motor is very quiet and smooth.
Based on the performance of mine, I feel very strongly that a 115hp, 2 or 4 stroke, would be just fine on this hull. The E-TEC should have more power than most 4 stroke motors...but the weight of a 115 4 stroke won't be an issue. These boats like to cruise at 20-30mph and any new 115 should easily do that.
I have been thrilled with the Suzuki, and they make a very strong 115...and also a 140, based on the same block.
Hope this helps
John
John W posted 04-15-2008 09:27 PM ET (US)
I just realized you were talking about a 19', not a 21'. I think a 115hp would be plenty for a 1970's 21' Outrage, and it certainly would be plenty for a 19'.
Good luck.
Tohsgib posted 04-15-2008 09:30 PM ET (US)
Belive it or not the 115 and 140 Suzukis have given almost the same numbers performance wise. The 150 is much stronger but is $2k+ worth 6mph on top end is up to you. Yes the 115 E-tec is a great motor but if you can find a 115 Yamaha or Suzuki for cheaper I would go for it being weight is NOT an issue.
ChiTown Cetacean posted 04-15-2008 10:41 PM ET (US)
Have the same boat (f/k/a Whaler 19). Hull No. 0021 Mine is powered with a Johnson Oceanpro 150 which provides power to spare. Per the factory specs on this hull, 65 HP is minimum to get the hull on plane. The hull is rated up to 175 HP. Most I've seen are powered with 150's. However, based on my experience and the specs, a 115 with the proper propeller should get you moving along fine.
sosmerc posted 04-15-2008 11:26 PM ET (US)
Sure would be neat to see a well done 115hp shoot out. What a great variety of engine designs we have in that particular horsepower range:
V-4 DFI (Etech)
inline 3 DFI Merc
inline 4 DFI Tohatsu
inline 4 Four Strokes...Merc, Yamaha, Honda, Suzuki

If you are interested about true power of marine engines, you may want to visit EPA's web site:
http://www.epa.gov/otaq/certdata.htm
Picked up couple of engine power figures from there:
Yamaha F115: 84.6kW
Suzuki DF115: 84.58kW
Evinrude E-TEC 115: 85.76kW
Suzuki DF140: 102.97kW
Cant say how reliable those figures are, but I believe those figures must be pretty accurate, because they are based on engine emission certificate.
Note, that previous figures are kilowatts not horsepowers. If you like you can do the math: kW x 1.341 = hp.

Austin Whaler posted 11-30-2008 03:56 PM ET (US)
Yamaha(115) = 113.450 HP = 84.6 KW
Suzuki(115) = 113.423 = 84.58
Evinrude(115) = 115.006 = 85.76
Suzuki(140) = 138.085 = 102.97
Keeper posted 11-30-2008 07:31 PM ET (US)
Our 1987 18 Outrage is powered by a 2007 115 E-Tec.
Top Speed with two regulation adults on board is 38 MPH @ 5600 rpm.
Minimum 1/2 tank of fuel, 6 rods, lunch, ice etc.
Plenty of power for two on the west coast were there is an ocean, not a salty lake.

An E-Tec 115HO or a 130 would probably be a more optimum engine for a 19 Outrage.
Few of us are interested in spending much time going as fast as we can. There are times, however, when an extra turn of speed can be useful. More than a few times I've had unexpectedly severe weather head my way when far from the ramp. It was nice to be able to get back in time to get the boat on the trailer before the storm arrived. As we age the possibility of medical emergencies can also arise. In the event of someone aboard suffering a stroke, seizure(sp?), heart attack or injury it would be a good thing to be able to meet an ambulance at the nearest ramp or waterside area as quickly as possible.
Under some conditions a smaller engine working harder will use more fuel than a larger engine working less hard. To determine where this trade off develops requires a good bit of research. If Evinrude has application engineers willing to discuss your repower questions they should be able to provide the definitive answer.

I have a [1973 Boston Whaler OUTRAGE 19 which has been] converted to low-profile with a SUZUKI 175DF. I can guarantee you [175-HP is] more than enough power. [The boat speed is over] 58-MPH with one person. I believe that 115-HP is plenty, but it is nice to cruise 40-MPH at 4,400-RPM.
ezellmer posted 12-05-2008 03:07 PM ET (US)
Is that 19 a 20- or 25-inch transom?
The 25-inch shaft 115, 115 H.O. and 130 utilize the V6 gear housing with 2.25:1 gears, and you have a huge selection of propellers. With the 20-inch shaft models you are limited to V4 propellers which are basically 15- and 17-inch pitch aluminum and stainless.
The regular 115-HP E-TEC seems pretty good on top end in the 20-inch models we run; low end is OK. With the 2.25 gears it might be a bunch better on the low end.
