The purpose, of course, was to prepare for bolting the Nissan outboard motor to the boat.
After the holes were drilled, I coated the inside surface with 2 layers of epoxy, using a Q-Tip. When I tested the bolts for fit, it was so snug with the epoxy that I decided not to bother with any additional sealant.
|First bolt is through, on the starboard side.|
|Second bolt is through, on the port side. I used 3" stainless steel bolts, washers and lock nuts.|
