Easy to Replace a Gasket on my Hurth Transmission?

[bene505]

Can I do this myself?

I spent Saturday removing our Hurth 360? transmission from the boat. It was slowly dripping transmission fluid into the engine bilge and making quite a mess.

I'm planing to wipe it clean, put some fluid into it and seeing where the fluid comes out. I'm thinking it's the gasket where the prop shaft attaches.

Does anyone know if it's possible for a reasonably mechanically inclided person to do this himself? I don't want to pay for a rebuilt transmission when this one otherwise works fine.

(I have some nice pictures of the removal that are still in the camera.)

Regards,
Brad

More background until I can test where the fluid is coming out...

A "mechanic" at a marina knew that the dipstick was missing from the transmission -- you know, the dipstick with the pressure vent hole in it. So he inserted a plastic cork into it. He used the type of cork that has a lever to lock it down tight.

I found the dipstick and replaced it, but the damage was done. I believe this is the cause of the drip, that is blew-out a seal or gasket.

Otherwise the transmission works fine.
