Hello,

I noticed a couple of my boats with propeller struts seem to loose the grease after 1 or 2 times running. After you grease the shaft the open hole is still exposed to water and air. It seems like the grease comes out as fast as it goes in sometimes. I'm not sure why the manufacturers don't supply a plug for this. Anyway I found a small screw that would thread into the hole. I then tightened it until I felt it bottom out against the shaft. Then I backed it off about a half turn and sealed it with liquid electrical tape. No more grease comes out that hole Any opinions appreciated. Howard
