1974 25 HP Gear Shift Lever

[Fellowship]

Hi Guys

Inherited the motor from a friend and trying to get back on line. Did fuel pump, points, clean up, paint job. Now doing water pump and lower unit fluid.

I got a problem, motor runs strong first pull, put in gear and after a minute or so I get a chug or a kick then it pops out of gear. I pulled the gear case got some milky lower unit oil checked gears no broken teeth no iron shavings??

What do you think?
Thanks

sounds like slow speed jet needs tweeking and the clutch dog may be worn out.
