What are you using for propeller size

#1 Post by Bearded Clam » Tue May 26, 2020 4:19 pm

I have a 22ft pontoon, with a tohatsu 115 2stroke wondering what propeller sizes you are using, my rpm range is 5200-5700, using a 14x11 at 5700rpms only getting 23mph... thought I would be getting alittle more

1999 25' pontoon boat with two logs. Heavy old boat with full furniture, boat is rated for 12 people.
1999 Yamaha F115 4-stroke

Stock aluminum 3-blade 13.5" x 15 pitch

27 mph @ 5800 to 5900 RPM with just me and my dog aboard.
25 mph @ 5800 to 5900 RPM with six adults aboard.

Big and ugly but we love our 1999/2000 Crest II DL with a Yamaha F115
