Thank you for the response! I'm guessing this will help me confirm the presence of fuel coming into the carburetor? If the pressure is lower than expected, then there could be an issue in the fuel supply anywhere upstream of the carburetor, such as these issues described below from the...

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...
