Boat motor problem

[HiDefFisherman]

When out yesterday and when i open my motor up it didn't open up all the way, about1/2 open. Well it had done this once back in May and then open on up. So I went on thinking it would go on an open up but it shut doun to a flast idle. So I turn around and headed back to the Dock and after going about 1/2 way, 200 YDS, she went on and opened up and was OK from there on. Does anyone have a ideal what's going on? It's an 1984 Evanrude 115 carbed. engine.

Hey Gillman,

My boat was doing something similar. When I had it opened up, or even when I was just taking off, it seemed the motor would lose about 1,000 rpms and would take a long time to get to plane. If I was on plane, it would just rev down, and I'd lose some speed, but then for no reason it would just fire right back up.

Just an FYI, I have a 2002 Opti max (225).

I had it down to Jet-a-Marina for repair. It took them a while to find the problem, but they got it fixed and it runs great now. They said it was a "module" that controled something to do with the rev/fuel, and they also had to replace some type of plug. They also went ahead and changed all my plugs, but they did that first, and it had no real affect.

Sorry I am not more technical, or mechanical I guess, and I can't be more specific. The fix was about $500, but definately worth it. It was sure nice to have full power back on the water.

Good luck,

HDF

A man don't need to be a mech.to tell his exspearance or ideal thanks a sack full. I worked on D9 Cats to 966 farmall's but the boat engines are a differant animal. I'll like the guy back a post or two, ask a question and you will get some help.
