Hello. I have a 14 year old 80 HP 912UL. I had the magnetic plug changed out a couple of years ago because it had been stripped. I have a question about the torque. I went to the Rotax class in Sebring over the winter and my notes say that the torque is 100 inch pounds, max of 140 in pounds. The maintenance manual that I have says 18.5 foot pounds, which is 222 inch pounds. 

Probably my notes are wrong, but I just want to be sure because 222 inch pounds sounds like a lot. Thanks.

Regards,

Damien

OK, I just answered my own question. I checked the newest on-line maintenance manual and the torque for the magnetic plug is 18.5 foot pounds. I should have checked before bothering the Matronics list. Thanks.

Hi Damien,



You are correct. That said I find 18.5 ft/lbs a little too much and makes removal a little too hard. That is one reason why the old style with the #40 Torx head stripped out, not ot mention some didn't seat the driver all the way to the bottom of the plug before they applied pressure to unscrew it. The whole idea is to tighten the plug so it won't leak or back out. I usually use less torque and it is secured on top of the torque with safety wire. I have never had one loosen in all my years. Try a little less torque it will work just fine.
