Rad 4 Racing Through Hull Racing Seal - Hot
I just installed my Rad 4 Racing drive shaft seal and ran my RXP off of a garden hose for about 30 seconds. The bearing carrier and the drive shaft got hot - say about 150 - 170 degrees. Does anyone here know if you can run this seal out of the water?

RAD 4 Shaft Seal
Mate, Thats not right!
2 Things. Did you pump grease into it before you ran it? There not shipped greased.
And have you machined your drive shaft correctly. When you slipped the bearing on, did it spin freely?
They should not get hot!

Hi its Kevin from Rad 4 Racing here.....
Your seal should not get hot whilt running in or out of the water. Please remove the seal and recheck the size the machinist has turned the drive shaft to and recheck that the grease has gotten in to the brg after you installed it. They are mailed to the USA with no grease as the MAF people get jumpy about unknown matter in the brgs.
If you have any further questions you can call me direct on 006421790440

I greased the piss out of it!
I preloaded the bearing and pumped grease into the Zerk when I first fired it up. The shaft was machined to 28mm... I guess I have to have it re-machined? My drive shaft installed snug and was not hard to install. I didn't need to force it into my pto...

I just put 7 hard riding hours with the Rad 4 seal and, so far I am impressed! It stays cool while in the water.
My stock carbon seal was failing. Last time out - I had horrible cavitation and a bunch of excess water in my hull. This time - NO water into the hull through the seal and NO CAVITATION PROBLEM.
