So I replaced the engine in my boat recently.
Serial number below.
The original block is an 090M (casting number I think, but this is how Rapido classed my block)
The block I got from Rapido is an 090 block.
The difference between these block are the metric bolts on the back (flywheel cover bolts, starter bolts and motor mount bolts)...other than that they are identical... I think.
Since I had to change starter bolts, the first set I got were a little long (1/8th") and didn't have the knurling or crosshatching.
Starter bolted up, all was fine.
After approx. 10-15 cranks, a couple of hours on the water, I started hear some "bad" noises during cranking.
Did some investigating and the starter is loose.
Pulled the new starter bolts out and compared them to the original METRIC bolts and the new ones are a little longer, the swollen shoulder was different and I decided to get another set.
I did... Now I have a identical bolt in dimension (should depth, knurling and thread lenght)...
I cannot get them to tighten...it feel like its bottoming out in the bolt hole.
My thoughts are to spray a little lube into the bolt hole and use my impact to tighten in down...
What are the odds I over tighten and break the bolt or crack the block? I've been using my air ratchet because of the lack of space, so getting much leverage on a ratchet aint going to happen, but I think I can get my impact in the right position to cinch everything down, but I don't want to F the block up and have to pull the motor again.
Thoughts?
