Thermostat ????

My engine is an 85 ford 351 and seems to keep a temp of 150 just fine when idleing around and such.... open her up and she climbs to 200 and stays right around their. Is this a thermostat issue or just what to expect? What do your temp gauges read at WOT?

That seems high and also weird that it climbs that much. I know my boat (97 merc) and my friends (91 merc), run at 140 and 160, no change from idle. Is it still in the green range? It could be a pump, restriction, leak, or thermostat issue. Also, it may be normal if it is still in the green range, but my thoughts are that it isn't.

I have a 2000 merc, and it always runs at 170. You should check out the manual and see what it lists as the temperature it should be running at.

when was the last time the impeller was inspected or changed?

could be a bad gauge itself or a bad exhaust.

Thermostats are fairly cheap and easy to replace. Try that it couldn't hurt.
