Thanks for the report. Good luck with the corrosion problem.

I'm out for a day on the lake with the wife and son tomorrow...can't wait.
I'm gonna put my 19p aluminum prop on to show my son what it's like to fly
out of the hole. He's gonna love it. I generally run with a 23p ss prop.
That keeps my rpms within the mfg spec @ wot.

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.
