Hey guys. I know this issue (impellers) is probably beat to death on the board but I was wondering about whether I should tear into my 1988 100hp Sea Ray (merc) outboard to check it. I get flow out of the tell tale but am unsure of if/when the impeller was ever replaced. <br /><br />Is is just the 4 bolts that hold the lower unit on? Should I just order a impeller replacement kit from someone like overtons?<br /><br />I'm pretty good with motorcycles and cars but outboards are strange to me.<br /><br />Thanks in advance for the help!
