I have a 7.4 GSI/DP Volvo Penta, 454 engine 1998 27 foot Doral, well last week I idled out of the bay which it ran just fine for about five miles then I pulled back to do a little trolling, after an hour I decided to pick it up and move to another spot and noticed that I couldn?t get on plan or accelerate over 2.5-3.0k rpms. I was able to idle back to my slip after which, I have replaces the fuel filter, the plugs and the Isaac sensor but no fix, and I can?t seem to locate the problem. Does anyone have a solution to this problem? Or have had a similar problem?
Thanks
