Hi,
I'm currently running a 3 blade 14.5" x 19" stock standard ss prop on an Evinrude 130HP v6 gearbox, pushing a fibreglass deep vee fishing boat (approx 2,200lb). I get 6,000RPM and 35-38kts @ WOT.
My reasons for thinking about a 4 blade prop are 1) sit on the plane at lower RPM (currently 3,500RPM is my minimum), and 2) better fuel economy and speed at mid-range RPM which is where i spend most of the time.
I am looking at a Solas HR4 14.25" x 17".
Any advise / thoughts or conerns going from a 3 blade to a 4blade as described above?
Is there enough grunt for the 130HP to swing the 4blade in question?
Appreciate your help
cheers
