Good oil thermostats??
 

What are guys running for oil stats? I had a hard time getting oil temps up last season, I am going to add stats, I was looking at these but want to make sure they flow ok,

Tim I've searched before and never seen these but like them. Particular the port labeling. The merc ones I have are nice but bulkier and aren't labeled so if you have a little abc going on like myself it's easy to get mixed up especially if your not dealing with them daily. So ya if anyone have used these chime in. They look nice...

Ps you'll prolly get temps up this year with that extra 500 plus rpm you'll be running. Without a doubt I truly believe stats are a must my last boat I couldn't build heat without coolers but they were stockers.

I installed a "Mocal" thermostat last year. I think I paid just under a hundred bucks. I have no complaints with it even tho I only put 4-5 runs on it. My oil wouldn't get any warmer than 140 without it. I had "cheese" build up in my valve covers and up the dipstick tube. After install no more moisture build up. Still takes a while to warm up but it gets to about 170 ish while cruising and hits about 190 while running hard

Thats the only thing about the basically automotive thermostats ....they usually open too soon and wont let the oil get to the 212* boil point of moisture ...I think the merc ones start to open @190 .... Earl @160 .....

My oil rarely gets over 200 with the merc oil thermostats. I do not have water stats, and boat in cold lake michigan water. I do not get milk on my dipsticks or breathers. Oil does not need to hit 212 to rid moisture.

I agree ...mine runs 190ish cruising ....running hard it will climb to 220+ .... have not had moisture issues .....m

I put on a canton and worked like a charm...

It has more to do with the air temp in the motor than the oil temp the same way a bathtub doesn't need to be boiling to create steam. The water has very little to do with the oil itself other than it occupies the same place, but the oil does need to not cool the air so much that it begins to absorb water.

I really need oil temp. Gauges next. Does anyone have a better sender location than installing in the oil pan? Definitely not pulling engines just to install senders. Running 1996 454 MerCruisers.

Many are in the filter head.

Sorry I should have been more specific. Im running 1996. 454 Merc's. Are you T'd into one of the rubber hoses or did you find a plug there to remove? Thanks for the insight!

Haven't done it yet, but while I'm changing out everything, and looking at tapping a 1/8 NPT on the opposite side of where the line comes into the filter housing and before the cooler

Im running Mercury, nice thing is, you dont need to figure out where or how to mount them

Mine are at the filter head, measured after cooler, I am putting them in my pans also and going to have a switch to monitor both places..

I put these on last year and they worked great.

Something to consider is if they offer optional temperature replacement thermostats

The mercury racing I have only offer the 210 deg stat, it's sourced from a 90s M series BMW. The road racing crown has machined a solid billet replacement that keeps it open at all times, which does us no good.

For what its worth I have been running the Perma-Cool oil thermostats with 3 1/2" x 24" oil coolers for 8+ years now. They have worked great and solved my oil condensation issues. I know they don't look very fancy but the thing I liked about them is that they use a standard car radiator thermostat "pellet" , so you can pick the temp you want them to open at anywhere from 140deg - 220+deg. Just buy the desired temp radiator thermostat and cut the pellet out of it, remove the snap ring on the perma cools and swap it out. Takes 5min... There are 2 in the swap shop right now (not mine) if you want to see want I am talking about. Also the ones that Full Force originally posted look like billet body versions of the same thing (they definitely plumb the same) so maybe you can do the same pellet swap with those. Anyway just trying to help, I know I don't post on here very much...

Oh and I settled on 195 deg pellet, my oil temps warm up fast and then stay between 200-215 no matter how hard I run it or what the water temp is like. my sensor is at the input to the oil filter head (before the thermostat or oil cooler ).

Thats funny you mention that. I have a mercury oil thermostat element on my desk. Was looking at it, and it looks like a regular wax type element. Id like to see if it will match up to a typical auto stat element

You're running Mercury oil temp gauges? I assume they make a kit that plugs and plays with the oil filter head? I haven't seen one.

Did you drill and tap like above (prefer not to) or find another means of mounting the sensor? Thanks

Many pans have 2 half inch drain plugs. You can utilize one of those ports which I've done otherwise you can drill and tap drain plug for sensor. You can get them all the way down to 1/8" pipe.

Here is another oil stat I never new of but honestly I think the perma cool ones have a better finish and a lot cheaper. Only advantage to these is their built with male AN so no need for adapters. I really like the earls that OP posted. Then again I just sold two perma cools for 55.00 shipped that work perfectly fine just don't have the bling.

No, this thread is about oil T-stats and Im running Mercury oil thermostats and Livorsi gauges

Remote filter mount with internal thermostat

That's cool, and it has a port for a temp guage.

I was looking at several different ones like those earlier. I think that is the ultimate especially if your starting fresh. With well laid out placement you could probably shorten up some oil hoses.

You think their 1/2" npt

for -10 they would be.

Are you referring to the -10 fittings ? no pipe thread on an O-ring seal

they don't make them both ways?

Good call. I didn't catch that. I was curious on port size so I could switch out to 12 AN but that changes things up for me anyway. I was just going to swap out to 1/2x12 AN.

Not that particular one any way. There's a bunch of cheap China ones on eBay with oring also.

That thing does look pretty cool, and would be nice and neat if starting from scratch. Pretty much the same concept as Merc's remote thermo filter head the Hp500's and what not used. Really makes plumbing easy, and neat.

I purchased 2 oil thermostats from Extreme Custom Marine. I delt with Paul a super nice guy and very knowledgeable he also sells them on eBay they are a take off of Mercs 1075 but at a fraction of the cost. These stats are super high quality and use -12 ORB lines.

I'd hate to see what actual cost is... lol. These look just like the stock merc ones I have.

Just removed the plug from on inlet side, installed temp sender (came with bushings) and then installed AN-10 fittings for the new hoses.

Excellent that's the ease of install I was looking for with a gauge but didn't know if the plugs went into and oil galley. Thanks!

Got my oil stats all done and plumbed in!

Are they what we thought. Nice piece? They look like it. I think I may sell my merc ones and get these. I like the streamline and mounting flexibility
