I am having trouble losing power on my 1988 Four Winns 215 Sundowner. It has a OMC outdrive on it and 305 Chevy motor with a Quadro jet carb. Yesterday when I took the boat out with 5 people the boat was barely moving. I saw I had some water in my bildge so put it back on the trailer drained it and took it back out. Bilge isn't hooked up. I ran fine then with three of us on it. Then we parked for awhile started up and it did the same thing. So I brought it home changed the fuel filter and looked around and everything looked ok. However over the past few weeks when I use the trim button I sort of get a shock and my battery was also draining if I didn't run the boat for a few weeks. So I stated using my on and off dual switch and the battery stays charged. So I headed back to the water to take one last look before I brought it to the marina. This time the boat wouldn't start. I had nothing when I turned the switch. The battery was still fine. So I played with the handle and finally I got the boat started. So than I hit the water and I noticed everytime I used the handle and hit the trim switch that I was feeling a decline in the speed I had. The boat this time was going faster than earlier but still not it's maximum speed. Is it possible that cause there is a short in the handle somewhere that it's taking that much from the motor or what could it be?? Please help. It's going to be another nice weekend. Shane

Re: OMC Motor Problems

I have the exact same power configuration in a Bayliner and suggest the following. Get the Bilge fixed ASAP! It's a no-no not to have one.

I look forward to reading the answers from others and I hope I never get a shock from my trim button! Sounds like you've got some wire chaffe, start crawling. I'd keep this thing on dry land until you have it fixed, shorts can arc, spark and make things go boom!

I plan on wiring a new bilge pump at the same time. I am just hoping it's not a nightmare and can be easily fixed. Shane

Does anyone else have any suggestions or have witnessed this same problem? Please Help!! Boats are made for water not land!

Re: OMC Motor Problems

sounds like a bad ground on the trim relay(s) or a harness problem/corrosion. A complete visual inspection of the trim electrical system and then test by using a voltmeter and checking voltage drops would be in order.
