There is no reason to over drill your holes unless your angle is not
perfect on initial drill..
There are professional steel templates available for a reasonable cost,
but unless you are mounting engines all the time not worth it...
Always make a template out of a scrap piece of plywood for your engine hole
spacing IE: Engine mounting holes say 13 X 10 center to center.
Than get one of these drill blocks, your hole will be the perfect angle every time! No need to wallow out the hole...
Works great on lifting ring bolts etc.....
Over drilling the fiberglass is OK, that will prevent future cracking from flex, however thick it is to the core of the transom .
Than be accurate on the remaining drill into the composite .
