Has anyone tried to put a different engine on the yerfdog 150? I have a Kawasaki

18hp v-twin lawnmower engine that is in great sgape and I was wondering if it

has ever been done adn also how much horsepower the stock engine has.

Erin, the stock Howhit engine was rated at 7.8 hp/7500 rpm.  If you go above

8hp, you may have to change the torque converter to handle the extra

horsepower.  See:

http://www.hoffcocomet.com/comet/aftermarket-torque-converters.asp.  I've

read that YerfDog 3206 models either have a 30 series or 40 series Comet

torque converter.  The 30 can handle up to 8hp and the 40 series up to 25.

You can search the messages at the home page/database for engine changes.

My other concerns would be the added weight, the axle's ability to handle

the power, and if the welded frame over the existing engine would allow your

Kawasaki to fit.
