I have a 46" gas boat with a Zenoah pro mod engine. I have to say that I love it! Nothing better than getting to the pond and knowing that your boat will start, and run great with out all of the fooling around. My boat usualy takes two pulls and off I go for up to 20 min of fun. (could be more with a larger fuel tank.) Gas boats are alot of fun, but your right they can be expencive. Might want to watch E-Bay for a good deal on one. You never know.
