Well my weekend was going well until last night. I took my boat down the shore for it's first Bay run. Ran great both Saturday and Sunday, not a single issue. Put the boat on the trailer to come back up to PA, washed it down, flushed both engines with fresh water for 5-10 minutes. Oil pressure and engine temp were fine everything ran normal. Trailed the boat home, launched an hour later in the river, ramp is a minute from my marina. As I'm pulling up to the dock, temperature alarm starts going off. Shut it down immediately. No clue what went wrong in a minutes time. I back flushed the system from the fresh water flush, started it up again and the temperature climbed again. I believe the impeller went. I did see a little bit of mud get kicked up when I was launching it which makes me think even more that it's the impeller, but not so sure. Any ideas as to what I should check?

You've gotta pull the raw water pump and check the impeller. Good news is that it is a pretty easy job on the 292(once you've done it, in the future you can swap both impellers in about 30 minutes).

btw, when you reassemble everything, I suggest adding a light coat of vaseline to the water inlet goosenecks before putting the hoses back on. Makes for easy removal in the future, as the mineral deposits and heating\cooling cycles will sometimes make them very difficult to remove...especially when you can't get alot of leverage to yank in those tight quarters.

You should check the impeller but also check and change the thermostats.Mine were sticking last year

Sounds like you probably lost the impeller. Good news is new ones are only about $30-$35 bucks and take about a half hour to change out. Definatley put some sort of vasoline or grease on the inside of the pump housing and on both ends and blades of the impeller when putting it back together.

If you have the cast brass pumps like I do, make sure to take a good look at the inside of the pump and the surface of the end cap. If there are gouges or deep enough scratches, this can cause it to loose its prime which is like starting it dry everytime and can destroy a new impeller.

I found this out the hard way!

Not to bring you more depressing news but if the brass pump is shot, get ready to hand over about $375 for a new one.

I just had to replace one a week ago.

I believe it's the impeller too. The temperature guage for the port motor had been acting up lately. The temperature would climb and then fall and then climb again and fall and go back and forth at idle. Which at first made me think it was the thermostat. I think they are like $10 or so. It is just really bad timing. I'm in the middle of the 2nd quarter close and my free time is limited. I'm having my marina price it out on how much it would cost to have them replace it for me but I'll probably end up doing it myself so I can have it for this weekend.
