I found this from a post many years ago on this site. This is still available and comes in several settings including 215 degrees. I think this is the best way for me to go? I believe I would plumb from engine to the filter then to this thermostat then cooler then back to the engine? Thanks for your comments and help.

Smoke and Dr. I was busy researching when you posted so I didn't see your responses. I agree that it should be installed per the instructions it's just that in the end it sends cooler oil to the filter and I believe that the consensus is hot oil flows better through the filter. With my last post I found something that I believe allows me to plumb the way I understand it should be? Thanks again for your comments.

If you're using a multi viscosity oil (15w-50, 20w-50, etc) then the oil should have adequate flow characteristics regardless of temperature. I think you're worried about a non issue.

You might be right about that. I do have a tendency to do that. My concern is that according to this site I will be installing (2) grenades and really want to do the best I can so that doesn't happen. Thanks again

Well, there's certainly a lot of guys much smarter than me on this site, so I'm not about to question them on their experiences and knowledge. I'm just a hobbyist with enough knowledge to be dangerous. Take my opinion for what it's worth!

These work great, that is what I used. but you have to ground the senders. The fittings do not conduct.

that sensor is not designed for that fitting, why would you want to introduce restriction in an oil line

I sent an email to a couple places and they said the plumbing drawing I posted here is "just like Mercury does it"
Also, do you guys think running the oil through the cooler against the direction of water flow is better than with with the water flow or no difference?
Thanks for your help.


Do not filter first. Out from the filter pad (canton racing) to oil thermostat, in and out ports to cooler (eddie marine), out of thermostat (canton racing) to oil filter (hamburgers the big one), then back to engine. I used -12 fittings, not -10 and installed one sender before the oil thermostat out of the engine and one after the oil thermostat.

F-2, I found out that the fitting was for a gauge and not a a sensor or sending unit. I did buy the correct fittings since then. Any opinion on post #81? Thanks for your comments.
