It will work with Teleflex push-pull steering, but not well. You heard right, turning radius will be compromised, and you probably will experience a problem with full tilting without obstruction, which could bend or break something if you hit an underwater obstruction at speed.

I took a second look at the picture and that blocked-off hose is supposed to go the the vacuum cut-off switch. And I don't see the switch. Somebody apparently removed it.

Also, it appears the ring is not a separate piece on that flywheel, so you will need to find a different flywheel if you intend to put electric start on it. Might be tough to find one for that year.

How much % would the turning radius be compermised? Will it take over 40% of turning? What is the other alternitive to get good steering? Also what does the Comercial with Interlock mean? Interlock? Cant seem to find a parts diagram for this motor.

I'd really hesitate to estimate the steering degrees. It's enough to be annoying to me, but others may not even know it can do better, nor care.

I have no idea what they mean by interlock. There are a couple of interlocks on the motor, for example you can't advance the throttle beyond the start position in neutral gear, and you can't pull the starter rope at high throttle settings. But these are "normal and expected" on older designs, which this one is.

"Commercial" is kind of self explanitory. Means an older model without all the modern bells and whistles, sold for rental or construction uses. Like transportation to an offshore oil rig, maybe.

Understood. Im also looking at a 69' 40hp. Its electric start and everything. but I worried because it says electric shift? I know that was a BAD stystem.

The electric shift in itself was not a bad system in its day. But this is today, and parts are $$$$$ and nobody remembers how to work on them. But all that does not matter because this one is not electric shift. The pictures don't show much, but from what I can see, I'd prefer it over the other one you looked at. Has electric start, and is a much quieter and smoother running motor. Can't tell, but hopefully it isn't as crusty either. Also a few pounds heavier. Make sure you get the electrical system with it (cables, etc).

Alright, yeah he just misread it. There are a few videos on it he made, il link them to. How much heavier? like 10lbs? If I cant get the ignition cable is it hard to find? I already have a shipmaster control set. I belive it comes with ignition though.

No Title

That looks like a shift lever to me. Therefore probably not electric shift.

Book says 15 pounds heavier. BUT, remember it is electric start, so of course it is heavier because of that. Actually, I'm kind of surprised it is only 15.

Those motors were OMC's bread and butter during those years. Very reliable. But of course, as with anything, condition is everything.

Stainless prop adds more weight. I'd go with the 1969 - great motors.

Just got off the phone with the guy, going over there at 6:30. He said these use the OMC red plug, is that true>?

My dad had a 1963 40hp, with the electric shift. Great engine. The 69 will be a much quieter engine than the 82. Better midsection design. As said before make sure to get the Wiring Harness

Numbers say 1981, but I believe it to be earlier, more like 75-76. Evinrude web site shows no 40hp for 1981? I have 3 with the fins they are factory standard. I have one motor that looks identical save the hood. mine is a e-rude hood that says Norseman , mine is a 1976 fins & all, these motors are a Big twin in even more basic work engine form, They come standard from the factory without a thermostat (look you will not find one) also you are not missing a carb silencer again they did not come with one. Work motor-basic in every aspect. & yes they are a bit to pull over, but very,very dependable. kodi

They did make and sell those motors in 1981. There are parts books for sale on EBAY if you wish to take a look. Some people say they never made a 1976 20hp either but my neighbor has one. It looks just the same as my 40hp but smaller. Some people think if it is not listed on an American site then it does not exist.
