I'm in the process of getting a Oil Cooler and Transmission Cooler (my old one is not handling it.Too small).While I was looking at some coolers I noticed Keith Eickert has Oil Thermostats and Transmission Oil Thermostats.Are they worth getting?Plus does anyone have any recommendations on Oil coolers.I have a 454 in my 24ft Superboat and the cooler that I have in there is a split SenDure Trans oil and motor oil cooler unit.I can only run so long until I have to slow down so the Motor Oil can cool down. I appreciate all suggestions.Thanks

I have a large oil cooler and one of the Keith Eickert oil thermostats on a modified 502. The oil pan is a Gill 14 quart and a remote mounted Napa filter (HP6 equiv.) My oil temperature has never gone above 220 degrees (thermostat setting) regardless of how much I abuse it.

I run both engine and trans thermos from KE. The engine logic was a given but adding themos to the trans was suggested to me by Huber. As far as coolers, SenDure seems to make a nice cooler.

Thats what I like too hear some good advise.I'm currently looking at the Eddie Marine chrome standard duty 12" cooler for my trans and the chrome Heavy duty 12" for my motor.You think that this is a good combo? Thanks alot Dave and Bob for the advise.

My engine builder is pretty strong headed on this topic. He said:
Don't ever run hard below 180 on oil temp and never go over 230. This is reading temps after oil cooler. I don't have a oil stat on boat. Eddie marine cooler and 14 qt pan on a N/A 540. Late this fall it takes forever to get to the 180 mark. I am going to wait and see if this problem decreases this summer when the water temps come up. If not I guess I will be buying a oil stat.
