'98 Intruder LU Seal replacement ??

[greglenz]

I have a '98 E150GLECD 150HP Intruder. 2 years ago, I replaced the Prop shaft seals and then did a pressure check. It maintained pressure over night, so it should have been sealed in my mind. However, that fall the fluid was grey. (I use BRP green fluid.) I have just dealt with it replacing fluid regularly, but now want to seal it up - I hope. Going to drop the LU and replace impellar and seals on the upper LU as a starting point. 12 years old, may as well right?

Anyway, my question for the professionals. Do you put the seals in dry, or do you use gasket sealer of some sort? Any tips or tricks to making sure I do not have to drop the LU again?

Thanks in advance,
Greg

Greg, you need to put some sealant around the outer perimeter of each seal. I recommend permatex ultra black for this. Also, you need to do a vacuum test as well. The outer seals at the rear bearing carrier and the driveshaft bearing carrier are unaffected during your pressure test, so this is important.

Don't forget new O rings too.
