Here is another one of my strange questions thats probably been asked and answered many times.
if i got a 14 inch diameter prop of say 23 inch pitch and it was a bit too much for a particular engine
can say half inch be taken off the tips of each blade and still let the prop be ok ?
I see there is a few props out there today that have blunt ends to them instead of the normal round
ear or cleaver points etc.
is there a benefit to this or does this just destroy the prop ?
I have a prop that is 13 3/4 diameter stainless and have been told i realy need just a 13 diameter
maximum for the engine to spin this up ?
the prop is a omc silver streak/srx 13 spline prop in very good condition thats been worked on for improvements with a 90hp e-tec engine.
my engine is a evinrude 54ci 60hp triple but soon to be 70hp (bigger carb change etc).
now if this prop is too big in diameter, can i simply cut the ends off to take down the diamet of the prop.
I have a 12.75 x 23 to try but its just an ordinary alloy omc prop,but might give me an idea if i can swing
this size ok.
the boat weighs around 500lbs all up without driver so maybe the 13.75 is too much diameter ?
But 12.75 could be about right.
this would mean just cutting off 1/2 of each of the 3 blades ,can this be just squared off ?
or does it need to keep a certain contour to work right ?
phill..
