what to put on pump bolts?
the ones that go into the ski? I just read 5 pages of "pump bolts" in a search and could not find the answer, I'm hoping to install tonight but not sure what if anything I should use...caulking? that seams to be whats on there, antiseize? or blue locktite? and the aluminum pump parts that mate up, some grease or silicone? thanks for quick reply....hopefully!

Threebond 1211 on the pump faces and blue Loc-Tite is what I use on the pump bolts.

Ive used Wheel bearing/ marine grease on the past 200+ pumps. But these were 4 strokes. Do 2 strokes have a tendency of backing out bolts or something

thanks ccw...tony, no, not that I'm aware, just better to ask before I put back together than to have to take apart because something was missed...you put grease on the bolts that go into the transom?

Antiseize is what I have used for 20+ years with no issues.

The problem i found with using anti seize is that whenm it hits salt water, it turns to a powder, the grease lets me remove the bolt without issue . No one wants to ruin a pump because the bolts wont come out...grease for everything....below the motor...

I always use clear silicone for sealing everything up with. Go around the bolt holes and a dab in the holes, helps keep any water from getting to the bolt threads in the first place and the silicone is just enough to prevent backing out.
