I have a 3.0 GS Volvo Penta engine on my 1996 Four Winns - inboard/outboard. When using my boat, we'll be out in the water for 5 to 10 minutes going at a high RPM, about 3 to 4k RPM, and then the boat will start to slow down automatically, as if I was bringing the speed down myself. Then it will continue reducing its speed and eventually shut itself off. After it shuts down, I can bring it back up just fine. Eventually it will happen again. It idles fine and runs at low speeds fine.
I took it in for repair for this and he changed the spark plugs and the power steering belt (he said it was loose). When he repaired it and took it out for 20 minutes at 4k RPM, he said it worked fine. But the problem is back -- I'm having the same problem I had when I took it in for repair.
Any help or assistance you can provide would be greatly appreciated.
Thanks.
