I changed my impeller (first time I've done it on my own) around 2 months ago, and took the boat out for the first time tonight. Before I even left the 'no wake' zone in my neighborhood, I was approaching 220 or 230 degrees. Took the boat out and noticed that the impeller bolts were really loose and one was close to falling out. Pretty sure this was the problem since it wasn't creating a seal.
I tightened the bolts and ran the boat on fake-a-lake, and water was coming out of the exhaust like I'd expect and there was no overheating, but the bolts were a little loose again after I finished... to where I could unscrew them by hand.
I've read not to overtighten these since they're brass, but I might be under-doing it. Should I be tightening these w/ a socket until they are too tight to loosen by hand?
