Hey yall, recently purchased this boat and have been putting alot of work into vetting it ready. Recently, i put in a new waterpump kit and ran it with muffs for a good 30 mins.........made sure temp was good, tale tale was good etc. motor idled great and throttle response was immediate. Went out to run it again and verify all before it finally goes on the water, and now it is hard to start and will not stay running........all help and guidance is greatly appreciated.
