Propeller Size - 1982 GB42 Motoryacht Single 120 Lehman

Postby kurt.reynolds » Fri Jun 15, 2018 11:41 am

I have a 1982 Grand Banks Motoryacht. Single Lehman, 120 hp diesel.

Went out for a sea trial yesterday and ran it wide open and achieved 2200 RPM.

I am wondering if the propeller we have is the right size. The propeller is a 4-blade bronze propeller, federal 24x16

In the bench locker on the flying bridge there is a propeller and I think it might be the boats original propeller.

I am also interested in having the propeller refurbished if anyone has any recommendations.

Thoughts?
