1972 Evinrude Pops in and out of forward

I have a 1972 65hp triumph I changed the lower unit oil and it ran fine for about an hour.then it started popping in and out of gear. I searched the message boards and determined the problem to be the clutch dog and forward gears so I disassembled it and turned the clutch dog over. I took it out and it still pops in and out of gear. I was wondering if the type of lower unit oil used would make a difference. I used an oil that stated it was recommended for all outboards including OMC. Is this acceptable or is there a specific oil I should use. Also could the wrong oil cause this problem. Please help.

D.Reese,

Yes, the hydro elecric gearcases required a different type of oil than others. Under the OMC brand it was called "Premium Blend".

Thanks ....Where can I find it, and is OMC the only brand that will work.
