UL-1 motor jacketed in an XL mount

[Diegoboy]

I was hoping I can combine all the pieces I had with ones I just ordered and make this work. It consists of a UL-1 motor installed on an OSE 540XL Carbon, Heavy duty water cooled mount, with a Kintec cooling jacket. Surprisingly it all fit nicely with only very minor modding needed. I was worried about the length of the UL-1 motor (56mm) not being an XL length (75mm) and it's fitment as well as the jacket fitting between the mount.

First, I installed the jacket as far fwd as possible, flush with the "shaft end" of the motor.
Next, I installed the motor to the mount cooling plate (Front).
Then I installed the mount rear ring on the back of the motor. There is a very sight overhang on the ring (about 1mm), but most of the ring is on the motor can.
I mounted the rear ring to the CF plates as HIGH as the oblong holes will allow.
I noted the front holes only lined up with the middle screw holes, but I wanted it in the bottom set of holes on the cooling face of the mount. I used a round file to oblong the front holes in the CF plates about 1mm towards the back of the mount, and... Tah Dah!!

Thanks. With the morning sun and my camera (not cell) I have taken a better pic...

It does look great, I've wondered too if it would work, thanks for finding out.

On a related topic - the most efficient way to mount the cooling jacket is with the water exit at the top bow-end of the can, and the inlet lower and near the stern end. This forces the hot water out the top and keeps the can full all the time the boat is in motion. If the exit is not at the very top there is an airlock and the very top of the motor is not cooled. If the water inlet is on the top or near the exit then the water circulation through the jacket is very limited - mostly a straight shot from inlet to exit with little water replacement.

Far better to have cold water forced in at the bottom and hot water forced out at the top. Sometimes the boat configuration won't allow this but most of the time it can be done. Guys worry all about the water pickup and total water flow - but give little thought to maximizing the performance of the jacket itself.

Thank you Jay, I'll change it before it gets installed in the hull

Thanks Jay for the input before I had to uninstall this.
I notched one CF plate to accomidate the inlet fitting...
