30 Horspower Saab Diesel with a variable pitch prop

"Ten horsepower on a 26 foot boat?"

Well it is assumed its a displacement boat , so huge additions of power only make waves and heat the ocean

A 26 ft boat woulds be hard pressed to get a 25 ft LWL so 5K , 6mph is the economical cruise .

I assume the boat would weigh under 12,000lbs , @ 2240 per ton , under 5 tons.

2 Hp per ton is a reasonable cruise with 3HP ton* (50% more fuel burn )would only get to near hull speed , another 1K

To go fast , in this boat would require a SL of over 3 , pure plaining , so were looking for a* hundredHP not ten.

3 times the speed , with a displacement hull shape , probably 10X the fuel burn, just means someone bought the wrong boat.
