Yeah I think I'll try again. i just don't get this I even spun the crank a bit during leak down test and had no change and as soon as she fires it starts sucking fluid. Thanks to all for our ideas!

The seal has grease. Don't shoot but when I went to get yamabond My local yamaha dealer only had hondabond so I talked to a couple of mechs they said use it. No wierdness with the primary gear and i didn't mich it. 6 psi for test it bleeds down to 5 after 3 min.

Hey thanks, I forgot to mention I replaced the crank with a newer one and the seal is installed correct

Anyone out there ever have a motor that passes a leak down test and as soon as it starts it sucks tranny fluid? I split the cases and replaced the seals twice still same problem
