Boat overheating?
I recently bought a 1990 Searay 180 Bowrider I/O V-6 (4.3 L) Mercrusier. I
have noticed that the baot always runs cool (140-145) when I am at a decent speed. When I slow down to 3-5 mph, or when I start up after being shut down for a few minutes, the temp goes to about 220. Once I get up to speed, it goes back down to 145 again. Also after I have shut down, on trying to start the boat I get the alarm and the temp is pegged. My mechanic says not to worry. Any Ideas? |

1. Get a new mechanic.
2. Install a new water pump impeller in the outdrive. The old one is not picking up enough water at low rpms. Tony "Bobo" wrote in message .com...

Along with everyone else, I agree that:
1. You have an idiot for a mechanic 2. You need an impeller. AND- 3. You should kick that moron "mechanic's" ass for almost roasting your engine with his stupidity. "Bobo" wrote in message .com...

What they said, but install a complete kit.

Boat overheating?
I suggest you check your water pump impeller. Replace the whole pump
housing when you replace the impeller. Just a few bucks more and you don't have to worry about that part for two more impeller changes. The impellers need changing every 2 years because they hold a shape that lets water get past after being in the housing for so long. They are hard rubber., I had the same problem with mine. When I was moving at a decent speed my temp stayed low but when I slowed down like in a no wake zone it heated up. I had to put it in neutral and rev it up until it cooled off. If I started it and let it run for any time without moving it heated also. I hope this helps. Bobo wrote: I recently bought a 1990 Searay 180 Bowrider I/O V-6 (4.3 L) Mercrusier.
