Repairing a front tracking fin

Recommended Posts

Caught onto a log of some kind the other night on the river. Everything seemed ok until I checked the boat afterwords on the trailer and realized I was missing the front tracking fin. Looks like the bolts that hold the fin on stripped out, any suggestions on how to remount a fin into place here. If I fill the voids with fiberglass resin and redrill the holes to tap the new bolts into, will this hold? Any suggestions would be great, I can get tracking fins from bakes, although I'm not totally sure about the hardware part...

I lost one a long time ago and thru bolted the fin with large fender washers and nylon nuts. I was unsure if filling the holes, drilling and taping would be structurally sound enough. I figure the nylon nuts would strip out if hit hard enough to knock off a fin. I can get a picture if you like.

I have heard options of that, was hoping to be able to just rebolt the new fin on, but that sounds like a reasonable option if needed... at least the front one would come up in the ski locker under my ballast pumps so it wouldn't be too hard to get to

Biggest problem I had after losing a front fin on my Sportster was drying out the screw holes sufficiently for filling with epoxy so they could be drilled and tapped for new screws, The drying process took 6 weeks or so. I think the 3M Adhesive does most of the connection of fin to boat though.
