Well, I pretty confused now! Is anybody out there really happy with
their prop (assuming you still have the 5424 engine and drive train).
And if so, where/who would you rcocmmend buying this from?
Please note we are now running our own website and can post
gear/equipment recommendations. We can also steer each other clear of
some of the bad deals there are out there.... This of course was not a
posibility while we were with Sailnet.
