What's BMT combo? And why does BMT cause problem if we submerge the
trailer of a BMT combo in sal****er when we launch the boat?

Boat, Motor, Trailer.

I just meant the trailer design and the hull design may mean you have
to dunk it to get the boat off. You might want another trailer style
if you can get it.

Thanks for the explanation.

Bearing buddies are a good idea but not a cure all. You should still
do a dissassembly, cleaning and visual inspection at least once a
year. Maybe more you are in salt water and go a couple times a week.

I don't think I will use the boat in sal****er that many times per
week. I guess disassembling the bearing once a year should be enough
for me.

Don't over pump your bearing buddy. It will squirt grease everywhere
and if you are really going fast with the gun you can blow the rear
seal out. As soon as you see the plate start moving stop pumping. It
is now under spring pessure and that is all you need.

Yes, I have heard about this previously (probably from here). Thanks
for the advice.
