I have a problem. I purchased a 500 motor that had a busted side case where the kicker shaft seats in the case. It came with a case to swap in and fix it. I spent a few hours tearing the motor down and replacing bearings, seals, and gaskets and putting it all back together. When I go to put the cylinder on I notice a HUGE problem. The side case I swapped in has a deck height way to low and it also appears that where the sleeve inserts into the cases does not have a large enough diameter either.
I tried the motor differences sticky and the pics won't work.
It looks to me like the base on the replaced side has been milled but I don't get why? Or is it just from a different year with a different deck height?
I'm fairly certain my motor was an 89.
Pic for reference.
