I was tearing apart my buddies 5hp when i took off the lower unit. Before i put it back on i want to make sure i replace the grease with just grease? Does anything special supposed to go in here?
It has to be a fairly light grease. In a pinch, I've mixed gearlube and axle grease. 105 is best. Hypoid would work, but the seals aren't all that great.
