Long story short...
Owned this boat/motor (1999 50hp 2 stroke) for 8 years, sold it to buddy (regretted it), and bought it back from him a few months ago. He used it an average amount, but hadn't done any service to it in the 3 years he had it.
Put fresh gas in and took it out and it started up fine, but wouldn't run over @4500 rpms like starved for fuel (no alarms). Was alone so hard to play with the choke and bulb while running, but pumping bulb then going back to seat, it did try to briefly rev higher. It had done this with me several years ago and it was clogged high speed jets. Removed carbs and sure enough jets were clogged, but the carbs overall weren't bad at all, hardly any varnish and floats appeared to be in good shape. I did not do a soak or change any gaskets/o-rings (good shape) and cleaned with carb cleaner and air. Also, cleaned the fuel filter but didn't think to look at the fuel pump. Did not water test, but on muffs it still doesn't run right and now it won't idle without throttle slightly raised. The fuel hose and connectors were corroded so I plan to replace those and the tank. Any advice? Should I replace fuel pump too and do a more thorough carb cleaning? I also went ahead and replaced impeller, spark plugs, and gear oil while I was at it.
