This is a new to me boat that I have done nothing to as of yet except for running some engine carb cleaner through an thaqt does not seem to be helping the situation. I am beginning to think I have a air leak in the fuel delivery lines somewhere. Or a cloged fuel filter. Should i clean the filter or replace it? The boat runs very good if you can get it up on plane at WOT. It's just getting there that is the problem. The inside of the engine is very clean and looks like new. I thought of trying to replace all the fuel line to the engine from the tank and maybe put in a fuel filter water separator unit while I am at it. That sound like a good idea? Im told I should check all the simple stuff first before taking on the carbs. Probably good advice. All of my issues are at low rpm. Any advice would be appreciated. It is a 2002 model.
