I just got my new 75 horse E-TEC on the water for the first time. Wow! what a difference from my 1976 70 horse, this is really a blast now, very quiet, super power at all ranges, incredibly responsive, downright impressive.

Does anyone have one of these on a Montauk or older 16 footer? I do notice a lot of feedback on the steering. I mean it really pulls to the right. I adjusted the fin under the cavitation plate but won't be able to test it again until tomorrow. As far as I know, I don't have anything special for steering. I believe it is the basic Teleflex unit. Thanks.

Congratulations.

What holes were used to mount the engine height?

If the engine is mounted too low, you can get a lot of drag and steering could be tougher.

as per that link, my engine is in the top hole, engine all the way down. however, i changed the fin below the cav plate and it made all the difference i needed, helped with the fishing too, salmon limits to twenty pounds.

Are you getting pulling at all ranges, or just WOT? The trim tab under the AV plate (the anti-ventilation plate) is for higher speed range.

As I'm sure others here will chime in, that E-TEC should be two if not three holes up, with a Stiletto SS prop. If you like the performance now, you will be really happy with the height/prop change.

thanks john k, had the engine professionally installed here in the bay area so i assume that they new what hole to put my engine in. that being said, i do have a viper stainless prop with it and after adjusting the fin it seems to have taken care of the torque problem, and after running a thirty six year old premix engine this seems like driving a ferrari after being in a '56 ford. thanks love this site

Bad assumption. As has been demonstrated again and again and again, many, if not most, outboard dealers/mechanics do not know where to put an outboard on the transom of a classic Whaler.

You already know they didn't set you up with a correctly adjusted trim anode. Why assume they mounted the motor at the correct height?

My E-TEC 30 was "professionally installed" by a dealer, who put it all the way down on the transom on my classic 13. When I took delivery the dealer said "the boat really goes with that engine, but throws up quite a rooster tail". Yeah, because the engine was way too low, but the dealer wasn't smart enough to know it! "Professionals" aren't always right.

LBM, in all seriousness, move the motor up a couple of holes on the transom. Many old-time mechanics don't know any better, but you should insist, or do it yourself. If you're impressed by the performance now, you'll be even more impressed with the motor mounted properly - every aspect of performance, from hole shot to top speed to mileage, will be improved.

after reading some of your responses, i went out and rechecked my engine placement, tophole = cav plate aprox 1" above hull directly forward of engine, so, if i read correctly your telling me to raise the engine higher on transom, this counters everything i've ever heard about having cav plate flush with or just above hull, correct me if i am wrong (wouldn't be the first time) also, holeshot is awesome, no roostertail, and, my steering has been corrected by adjusting fin.

That just doesn't sound right.

Engine mounted in the top bolt hole which is all the way down and the anti-ventilation plate is still one inch above the bottom of the hull?

Do you have any photos of this?
It just doesn't sound right to me.

lovemaiboat -- You're probably confusing the spray shield with the anti-ventilation plate.

av plate is bottom plate, right above prop, correct?

That is correct.

When a long shaft (20") E-TEC 75 is mounted all the way down on the transom of a 16'-7" Whaler, the AV plate will be about three quarters to an inch below the keel when the motor is trimmed so the AV plate is parallel to the keel.
