Engine kicks and bucks

I have a 79' Evinrude 35 Horse. When I go at any speed above idle, the engine kicks and bucks. At slow speeds it does it about once a second, but faster it does it much more. It shakes the whole 13 foot boat. I have been told that it is the clutch slipping out and catching again. Does anyone know anything about this, and how much it would be to fix it? Is it something I could do myself, after ordering a new part? Thanks -Ben

My bet is "clutch dog"... slipping in and out of gear. Used to happen with my old 13' Sport and 33 Johnson. Used to scare the heck out of us. We took it in and had it fixed. But that was in the '70s.

Easier to buy a used foot on E-Bay.

mine does it as well. It's an '85 suzuki 75hp. I thought that part of it was that it was older and it sat awhile, guess not. How serious is this problem?

My 1976 johnson 40hp used to do this. since I had the two lever controls you could actually see the shift lever move back when it happened. Being broke, I took a bungy cord to loop over the shift when in forward. didn't buck for 6 years after that.

Goldstem...you probably were (and are) slightly out of adjustment and the bungy cured it. His is a bit more serious if the mechanic said it's shot.
My 1982 35hp did the same thing, almost sounds like you are turning it off and back on real quickly. I adjusted it in forward more and it lasted another 100 hours or so but also made finding neutral a bit tricky.

Bigshot's got a good point. It could just be
the cable adjustment. That's easy.

Bigshot - I don't think mine was out of adjustment. As both myself and a few mechanics had a whack at it. it was solidly in gear and then it would kick out. My solution was just to buy some time but it worked until the motor melted in a house fire.

That is a weird one. Maybe your controls were shot. with single lever controls...there aint no way it can pop out once in gear.

OK....I'll finally admit it, I'm still back at square one on this one. When I hear buck and kick when you give a motor gas, all I can think of is my old MGA with the sh...y Lucas electrical system...when ever a cloud went over the Sun, the motor thought it was raining and started cross firing and the distributor would prefire and just generally...buck and kick. I don't get what you're talking about. I've read over this thread for the last 2 days and just don't understand. What's this about a clutch and in and out of gear? , I didn't even know my OMC had a clutch. Thanks in advance

My 1989 25 hp had a similar problem. It was overheating. The overheat sensor keeps the motor from turning above approx 2000 rpm's. I don't know if this is what you are experiencing, but I found I needed a new thermostat.
