Anybody have any experience with these? I bought a 5 owner fixer upper. It came out of the water running. Dual 350 mercruiser magnums on alpha ones. Replaced all fluids lubes and filters. Flushed hydraulics 5 and 7 times to get trim tabs and gimbals all clear of milkshake with cheap tractor hydraulic fluid. Still have to get the power steering fixed. First two owners were offshore high rollers who maintained it meticulously. Next 3 ran it until they sold it. Engine oil looked ok, replaced with 4 qt m1 hm 10w-40 and a qt of m1 racing 0w-30. What would you suggest for final fill of hydraulics? Have gone through boat front to back fixing things but I'm not nautically experienced. Lower unit of outdrive got rp marine syn, it looked a bit beat, has drive showers on it now. Any suggestions of things to look out for? And anybody know a boat mechanic near Dayton Tn who's good with bigger boats?
