Js550 coupler

Looking in the manual, it says to use some blue Loctite on the drive couplers. Just worried about them getting seized on then? I guess the Loctite also acts as a thread sealant? And does anyone torque them to 20 ft lbs like the manual stated?

Blue loctite does also act as a thread sealant, apply liberally and let er rip, but truefully they don't need locktite I have never seen one back off

Ok I just want to play it safe as my engine guy said back in the day when he torqued to 20 ft lbs, some of his race boat couplers came loose

They usually impact theirselves onto the crankshaft

I actually clean the threads and smear a bit of moly grease on the coupler threads. I do this to any engine.
