Sent an email to ask if this would work on my boat, and got a reply back the same day .. on a Saturday!
Ordered it here, received it very quickly, and it popped off the propeller with just a few cranks of a wrench.
A word of advice .. the propeller does come off without warning, and with quite amount of force. Be sure to leave the propeller nut on the shaft about a 1/4 inch behind the propeller, and be prepared for the release. I was holding the propeller by hand to keep it from twisting (didn't have a handy board to use as a wedge) and even though I was ready, it still was a shock. I didn't get hurt, but I wouldn't advise this.
I will continue to use Deep Blue YS for my boating needs in the future.
