Hello my name is ***** ***** I will be helping you today. Is 1 engine giving you a lack of power or both? When was the last time the engines made full power? Have they been siting a long time? How old is the fuel. Are these carbureted or fuel injected engines.
Customer: replied 2 years ago.
both, 1 year ago the problem started in June of last year. Siting time just over the winter this year and last year. I've own this boat for about 12 years and bring it out every year. Fuel injected engines

What kinds of questions do you have? What were you looking to do?
Did you want to do step by step troubleshooting. Or did you just want to talk about it, and have a conversation about the most likely causes?

Customer: replied 2 years ago.
some people are telling me it could be electronic
Expert:  Jason replied 2 years ago.
We have to figure out what the issue is before we can work on any kind of fix. If you want to do some troubleshooting. Start by compression testing both engines first. If that looks good. Then run both engines off of another fuel supply. Portable style outboard tanks work well for this. Let me know what happens.
