Found the OEM prop should be 13 3/4 x 21, right now I have a 14 1/2 x 19. I need to change the prop because it is making me run way too many RPM’s to get a good speed. Getting up on plane and cruising at about 20-25 MPH I am turning 3500 RPM and WOT is pulls 4200 and hits about 30 -35 depending on how I trim the drive. I have just the 140 HP 3.0 so not expecting 50MPH but just want to drop my RPM’s while cruising on plane.
I was thinking of a 14 ½ x 23 pitch, that should still give enough grunt to pull a tube for the kids and cruise easy at lower RPM from what I have read but I am not really sure what to get and have got good advice on here so far so thought I would ask. We have a shallow lake and run up the river a lot so will stay with just aluminum prop for cost and incase I hit something which happens a lot where I boat from what I have heard from a few local people.
