Don't know the exact diameter, but take the stick into the hardware store to fit it. I like to use nylon washers on things that don't get too hot for them as they're reusable. Ace Hardware has them.Thanks to all. So, a 17mm wrench for the fill plug, same size for drain. I read it's 0.44 Qt. of fluid. Anyone know the right size sealing (crush) washer?
Not sure it's a good idea to use nylon. I have a huge collection of aluminum and copper crush washers - cars, motorcycles, etc. I'm thinking the Hirth takes the same as my Honda V6 oil drain plug: same nut size, and seems to be the same washer size.Don't know the exact diameter, but take the stick into the hardware store to fit it.

Unless some boozo sailed with the trans in forward gear.It would be pretty hard to glaze them at 30hrs, I'm thinking it must be linkage travel?
Yikes! Do you have any idea how much force would be required to break the blades off a bronze prop? No wonder the gear is slipping (these are traditionally called a "gear," not transmission). I would remove and inspect, as a minimum, and expect to replace the clutch plates, as a minimum. I also recommend replacing the high strength bolts that hold the coupling disk to the crank shaft.With the blades broke off the prop who knows what has happened.
Today I removed the cable from the shifter and it still slipped. Now in the process of removing tranny. Sucha great design. The bolts that hold the tranny on are inside the bell housing and the bell housing is also on the mounts. Such fun!
