Yamaha 60hp 4 stroke high thrust speed

[jrjenner]

I have a yamaha 60 hp 4 stroke high thrust (all original) that I bought slightly used 3 years ago (2006 model). I have it on a 16 ft sylvan aluminum fishing boat. My top speed with just me in the boat is 33 mph (per my gps). With 4 people in the boat, my top speed (gps) is 32 mph. I want to get more speed out of the boat at top end and am thinking I need a different prop. rpm's are 5400 with just me in the boat and 5200 with 4 people. Any suggestions??

(i am sorry that i do not have the prop specs since i store my boat in Canada for the summer)

You should ask this in the Prop section, plus you'll need to know the exact size prop that's currently on the boat and what your RPM's are at full speed, without that info nobody can really help.

You might get more responces if you posted in the Yamaha forum.

right now your under propped, close but under best I can tell you is you need an F90.
your simply not going to get much more with that T60.
