well, instead of starting another new thread i will continue to piggyback off of this one. My boat is coming off the hill tomorrow. fresh 15.75 x 16 no cup. I also removed and cut off the keel protector that i have been loathing since i bought the boat. Sucker musta weighed 65/70 pounds and took a while to cut through it using cutting wheels. Anyway, I think I will gain at least a couple of knots without it as well as increased fuel economy and i think better handling as well.It was also a barnacle magnet, i wont miss that at all. But I did leave enough of a nub that I can have it rewelded back on if I decide for whatever reason I should. Not that i think i will wrap up a crab pot in my wheel or anything but if I do then I think thats what I pay sea-tow for.( no diving for me unless the water temp is 80+°. I will put up some new numbers thi8s week- keeping my fingers crossed.
