These are basically the rules we are working off, but as Craig said we haven't finalized our class rules yet. Stay tuned!

I like the 42 to 44 cubic inch class
There are many successful MODS for the 40-50 hp Yamahas
Here is a thread that covers the YAMAHA mods.

Don't forget you can use parts from other models and/or other engine makes in your build.
You can be very creative in your build.

I also have one of these hulls to go with the motor.
