    Default Berk. 12-jc thrust bearing failure

    Hello All, I've got a 73 Glastron Carlson CV-19ss with a pretty healthy 470 Olds turning a Berkeley 12-JC A. The thrust bearing in the Berk is starting to make a fair amount of noise. Any of you long time jetters knows how quick they'll go from noisy to catastrophic failure?
    Any chance anyone knows a good Berkeley rebuild shop in Colorado? I'd pull the engine and yank the pump this winter, but I'm hoping to make it through another season before taking the boat down again.
    Thanks!

    Tim

    if its making noise, it could fail anytime. get it repaired before it takes out the engine too.

    You're playing with disaster running it any more at all. Fix it while it's still cheap to fix. Once it goes out it gets real expensive. Duane HTP

    i was told a worn thrust bearing could take out a motor, soo... change it out

    x2 with duane, worst case is if it doesnt sink your boat you may be looking at pump replacement=have seen several that tried to make it back to the dock that had no rebuildable parts left. fix it now it will be a lot cheaper.

    You shouldn't have to pull the engine out to remove the jc.
