just got done the reverse install myself, not a big deal, kit says it takes 3.5 hrs, it took me about 4.5hrs just taking easy with a couple of beers, there wasn't any sealant used what so ever! just a rubber seal on the cable, the same type used on pretty well every steering cable and reverse cable since about forever on seadoo products both pwc's and boats!! anyone having an issue with drilling the hole in the hull about not sure what you are doing wrong because all you have to do is drill a 1/2 inch hole inside of the housing where the cable comes through the hull and it in itself is about a half inch hole so not too sure how any one could screw that one up?? as for it not looking like a factory install when done...it looks as good as anything could look. I have a 3 seater with ibr for the wife and mine is a 2 seater plain because I didn't want the ibr incase I tail landed the spark so I just installed the manual reverse on mine, it wasn't an issue about price, but it was likely about $500 cheaper than having Ibr (Ibr does work pretty nice though, the wife loves it, I just don't need it!) Next reverse install if I had to do another would likely take about 3 hours.
