Subject: RE: VMS (Steve) re: 2005 Alumacraft Navigator 165 tiller

I have a 04 navigator with a 04 yamaha 60hp tiller. I love the boat, stability is above average. Wishing to get a 70hp yamaha tiller (2012). How much more performance would I gain with the new motor?
Currently
1 person in boat 32 mph (gps) WOT, empty livewell, full gas
2 people in boat 29-30 (gps) WOT, empty livewell, full gas
3 people in boat, 26-27 (gps) empty livewell, full tank gas
3 people in boat, 24-25 (gps) full livewell, full tank gas
I had a Yamaha 11-3/8, 13 pitch, aluminum prop for the above tests.
I also changed the prop hoping for better hole performance and speed with a slightly lower pitch, it was a flop, I used a Solaris 11.5" dia. 12 pitch and it lowe4red all my stats by 3-4 mph on all ranges, poor choice.
Just curious, have you ever switched props on your 60 yamaha tiler?
