Alright. I picked up a 2017 Alumacraft MV1648 NCS and I LOVE it. It's incredible the difference in this boat vs my previous flat bottom.
Anyway, I threw my 1989 2 stroke evinrude 15hp tiller on the boat. 2 guys plus hunt load trimmed out correctly and I'm traveling 18.9 mph at 6200 rpms. I have a Solas 9.25 x 10 prop on the motor now. Prop slip calculated out to be 22. I heard that you want prop slip around mid teens for your average boat. I read up on prop slip, and understand what it is but I read on this forum that lowering prop slip will not help performance which just doesn't really make sense to me. Can someone offer an explanation?
I'm also looking at getting a new prop if it'll help the motor. I found an evinrude spec chart (https://www.rubexprops.com/boat-propellers/rpm-range/?make=Evinrude) and I'm 800 rpms under max rev (7000 per the chart). I used the prop calculator in the sticky and it suggested I go with a 9 x 9.
Thoughts?
