I just bought a used 1988 Bayliner Capri with a 305 Chevy engine OMC outdrive.
The boat runs fine until I go past 3/4 throttle. At that point, it will bog down and lose power. 3/4 power and under it runs great.
If I start from a stop and put full power it will accelerate fine until it gets some speed / RPM then it bogs out again.
Seems to be right at 4k RPM / 30 MPH when it has this issue, and it does it every time.
Like I said I just bought this boat, and just put it on the water for a couple of hours for the first time yesterday, so I may be doing something stupid.
I had a mechanic go through the boat to make sure it is water ready, and he gave it the OK, but I am sure he didn't run it at 4k RPM longer than a few seconds as it was hooked up to a hose on dry land.
Any ideas what to check?
