Lower Unit
Merc326,
The stock sportmaster, on my rig, was darn near unmanageable. When stock, it would not take a set and kept on hunting and pecking. Now it takes a set and runs. I'd say I'm about 5+ MPH faster than the stock unit and the handling is the reason. I have only had the modded unit on the boat for two trips to the water so I have not yet figured out it's optimum height above the pad, etc. I do have a hydraulic plate and a stainless marine indicator so I really get to experiment each time I go to the water though. So far I'm running up much higher than is supposed to be safe and still going up. I will go up more as soon as I raise my motor up one set of holes (3/4") because I'm out of hydraulic travel.
