...someone at Honda ought to be able to make a nice one cubic inch titanium alloy engine that you could easily get two hp from.
Honda is no stranger to racing, but to my knowledge, has not been involved in anything on the water.
As with any major supplier to a racing effort, the payoff is in exposure and branding to consumers, and technical/performance lessons inherent in competition that can be turned into sales, a.k.a., "race on Sunday, sell on Monday."
