Re: Low engine temp (130)when running boat in water
Well I guess if that's the case, why wouldn't I be able to bring the engine up to temp at 180 while running in the water? Thx

How about the best location for oil temp sender for those temp #'s? In the pan or the block?? Has anyone tried the different locations on the same boat for commparative results?? Ones guys 210 might be the same as another guys 240.??.......

PS. JGB - those are the same kind of #'s I've always seen. I run a 140 degree thermostat with bypass hose. I guess when the boats in the water the supply is just that much better. I would think a water pressure gauge would answer that question.

I've seen them in the pan and in the oil filter housing. Oil temp between 200 and 280 is fine so a 10 or 20 degree difference at different points on the engine is insignificant. I have been told that up to 320 is okay for short times also but it is a little freaky seeing it up there.
