what racing lowers will fit a 115 merc

[afr]

and what gears would i be able to choose from
and can a 115 merc run in the sst 120 opc class

There are no racing gearcases for the Mercs except the Merc Speedmasters. A VI would be the choice for anything in that class. Don't know if you could make the motor legal, (doubt it) but it'd be EXTREMELY un-competitive.

but they will bicycle if you dont back off for a pin
