    Verado L/U questions

    Does a 2011 Verado 300 Pro use the same lower unit as a 2007+ 3.0 or 3.2L motor?

    Splines are different. I had a set of 5.44HD verado lowers modified to work on my 250xs's. I had Marty Powell cut the verado splines off the driveshafts and weld opti splines on.

    Lot of talent to do that. Nice

    Why? What is the benefit? Didn't the 250's have TM or SM lowers?

    My xs's had fleetmaster lowers and kept popping the LH lower. I ran 50-70 miles offshore a lot, I wanted the larger lowers for reliability. They did effect my top speed by 4 mph
