1992 Celebrity 4.3L V6 Went out today and ran for about 15 minutes and engine started pinging and knocking so I shut it off. Engine dieseled for about 20 seconds after the switch was turned off, I guess due to high temps in the block. Got a tow back and after engine cooled down it started...
I put a new impeller in the raw pump on my yamaha 4.3L V6 inboard and got alot more water flow to the engine. I have more water flow thru the exhaust and manifolds afterwards so I decided to go to the lake to try it. Anyway the temp still crept up slowly to between 175 and 200 so I went back...
