    Default Best way to fix crack in pump mounting area...

    When I had my pump out for a replacement I noticed that the bolt holes in the transom "box" had some cracks in them, what looked like someone had REALLY cranked down hard on the bolts and just smashed the crap out of the fiberglass itself. My question is whats the best way to fix this situation and the strongest. I was thinking about grinding out the cracked bolt hole areas and then laying up some fiberglass mat and cloth for strength. Then redrill the bolt holes to fit (right now they're kind of big compared to the bolt size) and use a plate or large washers to make the clamping surface area larger. When I was idling around there was a small weep but once the boat started moving that area was pressurized and it was a pretty substantial leak.

    Any suggestions?

    From JBP's site it looks like this person made a huge plate out of aluminum to make the entire box a mounting surface.

    Really the bolts are to hold it in position, the sea-going epoxy it whats doing the seal, and holding of the pump. The bolts just need to be snug tight. If your getting water in, there is probly a bad seal, or gap in the epoxy.

    years ago when I was doing a lot of work on Panthers and the boats they came in, I used 3/16" aluminum to make plates for the exact reason you mentioned. Here's a picture of what the original looked like. I would also reglass the area before putting one of these on.

    I still have this one if you need measurements to make one.........nevermind, I doubt very much that I'll be doing anything with the Panthers anymore. For the cost of shipping, it's yours.
