So I contacted a marine shop and they said they're too busy to mess with it, that's it's not an easy job. They referred me to a machine shop. I called them and said I would have to pull the block off and bring them just that so they can put it in a machine to re-do the bolt holes. He said "good luck" finding someone who can do it without putting it in a machine. Can't even imagine removing the power head to get these three holes drilled out. Since it seems the only other option is to trash it or sell it for parts, could I just have the cover spot-welded onto the block? Seems crazy for 3 about 1/4" broken bolts to trash a whole engine. Any other suggestions?
he is right, you can either pull the power head yourself or pay someone to pull the power head
no you cant weld it to the block. you really dont understand wrench turning or gasket compression or an internal combustion engine if you asked that question
so do it right, pull the power head, take the power head to a machine shop. they will clamp it to a sin table, they will then index the deck surface to be true with the quill, then they will index the bolt to have the quill centered. only then will they step drill the holes.
expect to pay for 45 minutes of shop time per hole
there is the right way to do things, and they seem like the longest and most painful, however compared to the wrong way, are the least painful and least expensive.
