I need to replace my 150 HP Yamaha 2 cycle and have access to a 200 HP Yamaha. I just wanted to check if this is ok (capacity plate is unreadable)? Also wondered if anyone else has run that size motor on the 2100 Walkaround.
Thx, Roger

Did you Google the specs?

Or use the Col Reg formula that the USCG uses?

A quick Google search will tell you that your 200hp is fine

KBB will usually have that kind of info.

If it counts, my 1998 21 foot SeaSwirl dual console cites 200HP as max. My opinion is that it could take more HP, but 200HP is the spec for max.
