Mercruiser 3.0l broken starter bolts.

So here's what I've got going on I've watched videos of some options to not have to get the motor pulled. I've attached pics of the bolts in the holes and some pics of stuff I'm going to pick up after work. It's on my 97 rinker i/o. Do you guys have any tips or other suggestions to make this work. It's 1000 to have the motor pulled, broken bolts removed and everything re installed. And a lot cheaper for a few tools to give it a whirl.
