[QUOTE="k13west, post: 475668, member: 25362"] How do outboards of the same HP rating perform when one is a detuned large engine with more displacement vs a smaller engine that is tuned to maximize it's output? All other factors being equal, will a 30HP outboard with 550cc perform like a 30HP outboard with 750cc? If not, how will performance differ? My boat does fine during fishing season, but is underpowered once I add a duck blind and hunting gear. I'm looking to re-power and curious if a maxed out 30HP will give me that much more than the 25HP I currently have, or if I need to add the power(and weight!) of a 40 horse? Forgive me if this has been covered before, I couldn't find much using the search function. [/QUOTE]
