We have your answer! I can build you the strongest "XR" lower w/ a IMCO -2" satin case w/ any choice of gear ratio for $5,157.25 ready to install. We Use the IMCO Case, Mercury Gear sets (1.5:1, 1.35:1, 1.26:1), TCM verticle Shaft, TCM Prop Shaft, TCM Carrier, and the good bearings! You are also going to need a S.S. cav. plate. Our drive techs have been building drives for high HP for 10+ years, and know and understand the correct set-up.
Beware of the used lowers. If you do buy one, sent it to a reputable company who builds and serivces these drives to have it gone through. Chances are you are going to be replacing parts before you even use it, which could easily cost more than a new one! -Eric
