Ferm the 5/16x24 is a perfect fit, you saved me alot of trouble trying to figure out the treads! Lowe's does not sell fine thread 5/16 Grade 8 bolts, i used Grade 5 instead. They came in a pack of four so i said, what the hell lets use all three holes in the flywheel.
I got it hanging back on the transom temp for now. I couldn't get my bracket trimmed all the way down so i had hell getting the bolts back thru. Ended up using a ratchet strap on the cavitation plate to my lifting bar to angle it correctly.
I appreciate everybody's help! Now i know how to get her off when i find my new motor.
