I have heard from multiple sources that various manufacturers have used different measures for horsepower over the years. The most common story is that at one point most manufacturers measured horsepower at the prop, then some started measuring it at the crank so they could advertise a higher horsepower number (or the same horsepower cheaper), and later most all manufacturers measured it at the crank which is todays standard.
So my 1985 Monaco is marked a 260 hp. I was told that was a prop hp for that era and if measured at the crank it would be near 300 hp. Any truth to that? My 85 will out-plane and outrun many advertised 260 hp vessels in a race. I get that there may be other differences.
