Will a 13.25 X 17 prop hurt my Evinrude 115hp on a 26ft pontoon?

Answer 1

the only way you can hurt a motor with prop is if its way too small and allows the engine to over rev. most motors like to peak out between 5 and 6 thousand rpm with about 5200 usually being the max. your 115 should be right at 5000 to 5200. if it will not get that high you need to go to a finer pitch prop, if it over revs get a courser one. a good prop shop should e ale to dial you in easily

Answer 2

Check the turning and make sure there is no interference. If not...then no.
