Had a customer drop this boat off because he ran it aground and ripped the rutter out of the hull. pulled the engine to have the fiberglass repaired. Installed the engine and it runs like crap. Idle and throttle only it runs fine but under a load its detinating. Power balanced the engine and it passed, fuel pressure test passed, Spark plugs are bright white which would lead me to a fuel problem. Any ideas?
Thanks
