    Loctite for Impeller Boot Ass'y threads

    Does anyone know if it would hurt to use the Loctite 243 instead of the Loctite 577 as per shop manuals for the threaded portion of the impeller boot. They seem to be quite the same.

    They are both the same strength (medium). The 577 (yellow) is very thick (like grease) where the 243 is fluid.

    Boot? Do you mean the impeller nose cone? If yes, I'm surprised SeaDoo uses 577 as that is designed for metal threads. I never had issues with my plastic oem coming off when I R&R it several times (dry).

    This is for the threads on the impeller boot assembly not the cone. The seal portion in which the drive shaft runs through it to spin the impeller.

    That's a stock nose cone. Some guys use red or hatch the threads so they don't back off .

    I did not use loctite for that. I just got underneath the ski and tightened it as much as I could. I'm sure loctite won't hurt. The little fins inside the grate tear your hands up though. Try using maybe a wrench or something. One drop of loctite will do incase you have to take it off sometime

    I guess I am talking about the same thing? I slipped it over after the pump was on... I might be thinking of something else?
