Spare Props

Postby Evan » Sat Jul 25, 2009 7:28 am

Going to make a return trip to Bimini.
I want to get a set of spare Aluminum props for my 130's.
The problem is that I have 13.75 x 15 props on the boat.
The only thing I can find in a Left hand prop is 13.5 x 15.

The SS props at $300 ea and the Aluminum are $90.

Need advise!

You will probably will not notice the 1/2 inch in diameter. However, the AL has thicker blades ,thus more drag ,and probably only 2 mph slower.
AL is the way to go for spare props since they are lighter.Just spray them with corrosion X, boeshield and secure them. Maybe a 5gal bucket+lid with a small net inside.

I agree with conehead... and we are speaking of props as emergency spares, not primary wheels. They might ventilate more easily but they should get the job done in case of emergency. Buy both RH and LH at the same diameter and pitch so if you can only get your LH in 13.5 diameter, buy a 13.5 diameter RH also. Unless you are limping back into port, you should change props on both motors, ie. (examples) continuing on with a vacation or running back across the pond from the islands. I wouldn't run a steel prop and an aluminum prop, especially different sizes, for any length of time.

I am not sure if you have purchased your props yet but with my experience testing aluminum props I have always had to go with 1'' pitch larger with the Aluminum to gain the RPM as I was getting with the stainless steel props. I believe it is due to the aluminum wanting to flex more than stainless.
