Ranger aluminum transom torque?
HELP!!!!!!
I've searched all the way to the very end of the internet, then called a Ranger dealer..... (and the dealer says "just snug 'em up! That's the way we've done 'em since 19 and 68!")
I can't find ANYWHERE the correct torque on the transom mounting bolts (actually the nuts) for a '17 Yamaha 115 to the back of a '17 Ranger 188C!
I'm not taking the engine off, I'm only loosening the two left side nuts to install a bracket. I've got an All Aboard ladder that I want to mount, and it utilizes those two positions.
Can anybody point me to the answer? I wouldn't be so anxious about it if the transom weren't aluminum... (don't want to crush it, yet it needs to be "tight enough.")
Much thanks

Don't know if you have found the torque info your looking for but I sold those boats for several years and I would contact Ranger direct to see if they can provide you with this info

If you can't find an answer, and you have a torque wrench .... why couldn't you use it on one of the nuts to try and tighten it a bit more & see what it reads when the nut moves ?? Then you'll have your answer and know how much torque to use to tighten them back up. Then I'd apply a dab of Loctite Threadlocker ... just to insure vibrations don't loosen them.

No, fellas.... I've not received the "certified correct" torque. It's almost irrelevant what Yami says.... I don't want to crush the aluminum as I don't know if it's a sleeved hole. They are double nutted on the exterior. I can't find a number for Ranger direct, and like I said... I called my local dealer.... he's a very happy old feller who's proud to proclaim that he's the oldest original Ranger dealership in the state of Georgia. I'm an aircraft mechanic by trade.... I just can't bring myself to "guess" at the torque. I'll definitely reply to this thread when I've found the answer.
