Hi Dick,

Out the left side of the upper case, and in the right side... NOT through the top...

Goes from the drive to a fluid reservoir, to a pump, to the cooler, then back to the drive... Not sure if it is like DPM... Could be, as it was a drive used by Drew Marine, for prototyping... Temps went from 280 degrees to 180.

I am also looking into installing a thermostat after the repower...

This is the drive. It was plumbed this way on the Advantage in the pic before I bought it for my repower.

Hope that helps,

How would the temp vary, i.e. why are you looking into installing a thermostat. I have a thermostat with the prefered temp range that I'm thinking of adding later on.

Rich,
It is hard to see where the Out is on the case. Do you have a better pic of it?

Dick

looks like a drive shower.

Dick,

The out is on the port vertical upper case, and the return is on the starboard side..

It looks like the opposite of this pic in which you can see the return.

As far as it "looking" like a shower....

Clear as day to me... Then again, maybe it is a shower...! Just oil instead of water, and couple of hydraulic lines to move the oil around......

Rich,
Mine differs in the fact that it draws lube from the lower and injects it right on the pinion gear teeth.

Maybe Strip was looking at the hose going to the cap?

Dick,

Mine works in a similar manner. It goes to a tank from the pressure side, then to a pump, then to a cooler, then to the drive, and is sprayed at presssure on the pinion gear, then down to the lower, and up to the out fitting, and cycles all over again..

Strip could have seen the shower and gotten confused.. However, for me, it's as clear as day... I have a shower, which has a braided hose, and then there are 2 high pressure BLACK hoses for the drive cooler visible in several pics.

Anyway, like I said, clear as day in the pics I posted..

Tom,

just like on a car, boat, plane, etc.. When you first start, the oil will be cold, until it gets up to temperature. I do not want cold oil all the time on the gears. Oil has an operating temp range that is optimum. My thermostat will be in this range.. I want to control the efficiency, and aviod oil that is too cold, or too hot on the drives..

Hope that helps,

R

The oil returning from the cooler, isn't going to 'spray' anything. The upper gears are totaly imersed in oil. The cooler only cools the oil. A drive shower doesn't do schit to cool oil, only to keep the upper case clean, thats it. I have a drive oil temp gage instaled last fall and did some testing with a simrex drive shower and without. NO DIFFERENCE in oil temp.

The current cooler offered is from Drew marine, and I personaly think its a GREAT product that I want to buy and add to my setup. I have spoken to Drew Marine an length about their system and am impressed.

A little pricy, but if it lowers the oil temps by over 100 degrees, I think that really helps the oil, and the drive stay intact.

Jeff,

Can you explain why the gears would not be sprayed? I would just LOVE to hear this... You must be studying that new branch of physics..

As far as the drew comment, may be you should read the entire post..
