I have a 15 foot boston whaler with a 1978 70HP Johnson, currently I have a aluminum 13 1/4X17 prop, and than I picked up a 13 1/4 X 21 stainless steel, Which one is best for this engine?

What is your RPM at WOT for each prop? A 21"SS on our 15' with the same engine was a great prop when running light and fast. We usually kept a 19" SS on the rig when hauling big folks or pulling skiers. Great combination.

After all this,,The prop Hub was bigger than my lower unit, So back to square 1, Trade my prop locally
