Hello,
I own a 2002 Wellcraft 190 Excalibur Sports Platinum w/ a Volvo Penta 3.0GSP-C engine. I've owned the boat for 3 years and consider myself to be an inexperienced boat owner. I have an issue where the boat runs normally for awhile (~3 minutes), then the engine starts to stutter, lose power, and die (for some reason, the oil pressure also reads zero after the engine dies). The boat restarts and runs normally upon restarting, then stutters and dies once again. It seems this cycle would continue to happen indefinitely, but there have been times where I run the boat for ~10 minutes with no issues. Overall, the issue has happened about 10 times in about 2 hours of boating time. I placed a link to a video of the problem occurring on my boat with chapters tracking how the status of the boat changes with time:
I'm assuming the engine is either starved for fuel or air, so I cleaned the flame arrestor w/ carburetor cleaner (it looked pretty greasy) and replaced the fuel filter (slight yellowing at the bottom of the blue ceramic filter). After making these changes, I am still experiencing the issue.
My best guess is that the carburetor has a reservoir of fuel available, which gets depleted after a few minutes due to a restriction somewhere in the fuel supply lines. I think it is possible the fuel tank pickup tube is blocked by debris, as some debris entered the tank when I was looking at the fuel sender.
I would very much appreciate any thoughts/suggestions about how I should approach solving this issue.
Thanks!
