Hello, thx for your help. Lokking at buy a 1998 evinrude 90hp ocean pro. I went out to day on boat and the motor had not been started since december o5. Motor started right up and put it in reverse and gears didn't mesh very well. So put gear back in neutral then put in gear for forward and same thing gear not meshing well. Tried this several times and a couple times it went into reverse perfectly and same thing going into forward. Runnig forward wide open no promblem and backing up in reverse no problem.<br /><br /> The fellow said he took it to a mechanic and the mechanic lubed the hell out of the SHAFT and said wait a few minutes for lube to drip down shaft. They started it and it shifted fine then put boat in water and no more problems. Mechanic said that sometime just setting awhile it loses its lube and perhaps a little corrosion sets in causing shifting problems and gears not meshing.<br /><br /> Now i am not a marine mechanic but I thought drive shaft entered lower unit via SEALS, so how does one lube the shaft that will help gears mesh for forward and reverse when gears are encases in the foot with fear oil?? Thx for your help.
