I've heard it said that "older engines" had their HP rated at the engine whereas "modern engines" rate HP at the prop.
Is that true?
...and if it is true, how do you compare?
For example, my boat has a 1969 25HP Evinrude, and it is just a wee bit under powered. An older 40HP would be nice....but maybe I should look for a newer motor. Is an "older" 40HP like a Modern 35? Modern 30? Modern 25? If an older 40HP would be good, what size "modern" engine should I be looking at?
ps: I'm thinking a modern 2-stroke, not 4-stroke
