You need to take a fresh look into the motors that fit this class.
We already have a 45 cubic inch class T-750 using 43 cubic inch triples and twins up to 49 cubic inch.
We don't need to duplicate ANY motors.
YOU RUN THESE MOTORS BONE STOCK.
YOU ARE IN THIS CLASS TO GAIN EXPERIENCE AND HAVE FUN!!
Some would love to run a GT30 4 stroke 30 hp Tohatsu....YOU CAN IN THIS CLASS.
Others want to run the common low cost 35 hp twin OMC that runs in APBA.....YOU CAN IN THIS CLASS.
THERE ARE MANY MAKES AND MODELS TO SELECT FROM.
