300/440/550 550 motor question

[Strange]

i picked up this ski that needed some work done. i took the motor out and it wouldn't rotate i think it was the stator stuck because once i pulled the flywheel out about a quarter inch the motor spun fine (i cant get the fly wheel off any farther then that, already broke two pullers)
my question is this

there are some scratches on the inside of one cyl, i think i could just hone it a bit because this things just a toy, not a racer and it would be fine. but i would HATE to hone the cyls and drop almost 80 bucks on a gasket kit and then i have a crank problem. so i need a new engine anyways
if i take the bottom end apart will it be obvious if my crank is in good condition?
whats you guys input?

here are some cyl pics, all the same cyl and same little area

put some heat on the flywheel to get it off.......

go pick up a hone at a autoparts store and hone it out....... contact Superjet113 here, he has a hookup on gaskets, should not cost you very much. 80.00 is outrageous.

cool thanks man, ill shoot him a pm,
so if i take a look at the crank would it be obvious if its out of spec and busted? pretty much if it dosent jiggle should it be good?

also how would i tell what year this motor is?

look on craigslist for an old 750ss couch. you can get a whole ski CHEAP! especialy in the off season. Swap the engines.
