Can someone tell me the prop shaft specs for the 380/387? Specifically, diameter (25mm, 1", 30mm, etc), taper (10:1 or SAE, etc.) I'm thinking of buying a MaxProp or KiwiProp for my current boat, but am looking at a 380/387 for down the road in a few years and am wondering if I can keep the prop at that point. Since feathering props are pitch-adjustable, its more likely it would be usable on multiple types of boats, as long as the shaft specs matched. I sure could justify the cost if I knew I could transfer it to a future boat! Thanks in advance, Tim
