sounds like you need to read ethanol, carb cleaning, compression check.

you have 3 carbs if they are not working properly, it is a very easy way to ruin your engine. no fuel thru the carbs, no oil to the cylinders, BOOM

Welcome to the iboats.com forum. Tashasdaddy and the other experts here can help you with any question about your boat, motor and trailer. I my opinion this is the single best resource for recreational boaters. The Engine FAQ thread at the top of the Repair & MTC forum page are very helpful. Good luck!
