[motorcarmike]

Hey all,

Im new to the boating world. Ive got a 68 9.5. on the back of the lower unit there is a small hole. maybe 1/16" that when the outboard is tilted on the back of the boat, milky gear oil drips out...

can anyone help with this? is this normal?

any help would be great!

thanks
mike

If your talking about the gear case that is not normal.I have a 69 18 hp and a 65 6 hp and niether has a hole in it.The milky grease means water is getting into the gear case.Is the hole below the water line?If its up higher by the telltail and looks like snot coming out your useing to much oil.ps never use regular 90wt,gear grease because marine gear grease is soap based and will mix 50/50 with water and still lube your gears.
