Default 23' Repower Old'sCool

Finally......Originally planned on I.M. Mike and Suzi 300. Logistically, couldn't work it out. Shout out to NoBones for his offer and Mike at I.M. If I went with Suzuki, Mike would get it.
Ken, I owe ya a cold one!

I went with the Yamaha 300 locally. 7 hours so far. I tried the Yamaha 3 blade SS Series 17P for 2.5 hrs. It was just OK. Hooked up with Ken at PropGods and got the Powertech 15 1/2 x 16 4 blade. Results are below. I'll post some pics early next week. Happy camper so far!

Hermco bracket, engine is third hole up, two guys (~320# total), 1/2 fuel (~60 gals.)

Lowest I could plane today was low 20's kts. I'll work on that as it was kinda rough.

Nice cruise was ~ 4000 rpm

RPM Speed GPS Kts GPH
1500 7 2.2
2000 8.1 3.5
2500 10.5 5.4
3000 14 7
3500 25 8.8
4000 28.5 12.5
4500 31.5 16.9
5000 35 21
5500 37 25.6
6000 42.8 29

Ken at ProGods helped with this and I'm satisfied! He figures good numbers on prop slip at WOT and prime cruise.

Sits nice in the water also.
