So I finally got the engine running great and had a blast on the water this weekend. However, on the way back to the dock, I was going 40ish mph and noticed a knocking noise. So I immediately throttled dow, turned the engine off, opened the hatch and didn't notice anything. Cranked it back up and still heard the knocking, it's only when it's in gear. I'm suspecting something from the outdrive. It's more of a deeper sounding grumble but isn't constant, which is why I called it a knock. I went back to the dock going around 15-20 mph on a plane, the sound sped up/slowed down with rpms. It's an alpha one (200/v8) connected to a mercruiser 260.
At home on the muffs I can still hear the sound but it's not as deep (when in gear). With the engine off, the prop spends freely in neutral both ways. In forward it only spins freely one way. In reverse it spends freely one way and slightly the other - can feel the gear try to stop it but I can over power it by hand.
So give me the bad news guys, haha. I'm hoping just a shift cable is out of adjustment. I had some chattering valves on the starboard side of the engine, got those quiet yesterday and also noticed a pinging/rattling noise coming from the flapper door in the exhaust pipe just after the second rubber coupling on the starboard side exhaust downpipe.
