Impeller issue...
When you replace your impeller use a quality Mercury part, I bought a Sierra pump kit and kept it on the boat just in case. I put it on a year ago yesterday. Never had real good water pressure with it (10 psi max). Well yesterday I was coming back to the marina and came off plane and our gas dock girl said there was alot of steam coming out of my exhaust. Thought maybe it was the cooler air and water. Gassed up and went back out, now I'm nervous and am stareing at the water pressure gauge.....and sure enough within 20 minutes the pressure dropped from 8 to 7 to 6 to 5psi. So i nixed the run down the bay and went to our favorite spot to look things over and still be on the water. (and get rid of my hangover) We took the pump out and apart and 2 of the fins were broken off and luckily still in the housing, all the other fins were cracked and ready to fall off. Get this, saturday before we left the marina for the weekend I bought a Mercury Quicksilver impeller (just an impeller) and put it in the tool box, something told me just to do it. We put the impeller back together and alls well....15 psi and no steam
So....to make a long story longer, buy quality parts. The Sierra part lasted a year to the day. The previous impeller was in for 3-4 years (a Mercury part). Yea Yea I know you should change your impeller every year. Spend the extra few dollars you get what you pay for.

Anyone want to bet that the Merc part is actually a Jabsco piece with the price doubled (or more...)??
I run Jabsco pumps bolted directly to nose of the crank, so they're super-easy to work on. I average 3 years on impellers, but I usually loose them to blocked water flow (and therefore over-heating), not old age.
