So I am having a problem with my 2003 crusader inboard fuel injected V8 engine. When I hit waves or when I turn abruptly the engine sputters and drops about 1500 RPMs. This happens only when there are waves or if I turn sharply. It the water is flat the boat runs just fine with no problems. I have checked all electrical connections for grounds and ignition wire set up and have run the engine on a external tag to eliminate fuel issues. My mechanic who takes care of my other small boat engine is mercury trained and is checking into this for me as a favor. He noticed some issues with the distributor cap so I've ordered one of those to replace, but this has us both stumped. It sounds like the key switch is being shut off and then turned right back on, but it only happens with sharp turns and when I hit waves under load.
Any help or insights would be so appreciated!
