OS Max 21 OB. Version 1 vs. Version 2

[Randy Rapedius]

Is there a performance difference and/or price difference between the version 1 water cooled OS Max outboard and the version 2 air cooled?

I would say yes.. its minor.. but yes.. the V2 has a tick more grunt off the corners.

My lap times were better with the V2. Make sure to TUNE the low speed needle!

The muffler extension on the v2 seems to give more power. Now in IMPBA you can put that on the watercooled version
