More Transom Questions

[PAR]

There are a few different techniques for bonding the transom pieces together, but your notched trowel will work fine for spreading goo. Just make sure you use a "fibrous" filler material (silica, milled fibers, cab-o-sil, etc.).

Since your plywood has been precoated, you don't have to wet it out, but it does have to be scuffed up with sand paper, 80 grit or less will do. Also since you only have two coats of epoxy, you may want to wet out anyway (after scuffing) just to insure water proofness.

I use temporary screws to hold the pieces together while the epoxy cures, but clamps or weights will do also. Remove and seal the holes when cured.

When you bond the plywood to the transom, make sure there is plenty of ooze out around every edge of the plywood, where it rests against the hull. Gently radius this ooze out epoxy, to form a nice fillet around the full perimeter of the transom/hull joint. You may have to mix up more thickened epoxy for this. This fillet is very important.

After the fillet is completed, then tab the transom repair into the hull shell with several layers of cloth tape. You'll want several inches of overlap on the plywood and hull for a good tab.
