Prop Shaft Line Cutters

Spurs line cutter on FPB 64

You are looking at the business end of a Spurs propeller shaft line cutter. These are a part of the standard specification on the FPB64. In 45,000 miles of cruising on the FPB 83 Wind Horse we have yet to permanently wrap a line around the props (and being outboard they are at more risk than the centerline prop on the FPB 64) so the combination of full protection from the skegs and the Spurs line cutters is working.

    Hi Steve,
    I know that the SPURS system is Inox and I think that the shaft hub here is made of aluminium. As I dont see in the picture any insulation between the Spurs and the aluminium structure, I’m thinking to electrolytic corrosion…how did you solve this issue here?
    Thanks a lot and good wind!
    Alberto

    Hi Alberto:
    The portion of the Spurs which is attached to the aluminum is isolated. We have this same detail on Wind Horse and it has not been a problem.
