Bottom motor mounting holes ( below motor well drains) seem to be blind holes, therefore had lag screws in them. They are stripped out. Can I repair as stated in other threads and just put new lag bolts in to hold bottom of motor? Considering removing motor and oversizing the holes, then using epoxy to set marine plywood plugs. After this is cured reglassing and gel coating the transom. I don't have any other holes in the transom and it seems to be solid. Will this method hold the motor? Other Whalers I have looked at have the motor mounting holes go through above the bottom of the motor well. This is the only one I have seen with the going in below.

There is a reason that motors should not be mounted with lag bolts.
I think you just found out why.

Drill the "Green" holes in this diagram and raise your motor up to the proper height.

Fill in your old stripped out lag bolts holes and move up to the 21st Century.

Just for your information. Your Montauk is 16 feet 7 inches in length and called a Montauk 17.

I value your opinion, so what is the proper motor height? I always thought the cavitation plate should be even with or just below the keel. Has that changed or was I just plain wrong?

1-1 1/2 inches above the bottom of the hull.

This is approximately 2-3 holes "up". The top bolts should be in the 3rd of 4th hole when counting down from the top.
