What type of gasket sealer are you suppose to use for the manual nv-350 transmission? I just rebuild mine and I'm pretty sure I'm not suppose to use regular silicone gasket sealer.

Please be more specific...

am i suppose to use silicon sealer or anerobic?

for the case and for the rear peice that covers the bearing around the input shaft and the output shaft silicon or anerobic sealer?

It calls for anerobic. I usually just use grey silicone. :shrug

i use anerobic. ive tryed many others, and now im good at dropping the tranny to fix the leak.

I use a sealant called Yamabond 4 from the local Yamaha dealer. I put it between the cases of the trans and everywhere else on the engine. There is not a drop of oil anywhere outside the engine or trans. I also put it on the oilpan, without a pan gasket, temporarily because no one had the gasket in stock and I was ready to crank my engine after the rebuild. But so far the engine has ran a month with no hints of a leak. I am going to see how long it lasts before I put a gasket on it.

The stuff works really well if you put it on but let it dry for a few mins before you put the parts together. That way it gets sort of a sticky texture that bonds to the metal.
