My prediction is slower out of the hole, slower top end at mfg rpm spec
(42mph). WOT RPM probably won't change much due to the larger diameter
prop (pitch being equal). Cruise will be about the same.

Had my boat out this evening. Your top speed prediction was dead on. I can't
tell much difference in acceleration or cruise.

Now to see if the new prop affects galvanic corrosion the way I'm hoping.
