    Angry What else could go wrong!

    So after buying a jet ski having the engine blow up trashing the case after two hours I though my luck was bad enough.. Well just got a used engine from a fellow gh member and the crank is rusted up and different colors.. this mean I need to rebuild the crank? I can see it on the side journals but not on any bearings..

    About to just sell this f#ucking thing as is for parts. Seriously.

    The OEM rods have a copper coat on them, so don't confuse that for rust

    Question

    Oh its definitely rust I can even see some where the main crank bearings sit in the journals. Not sure if any rust is on any bearings since I cant see them, but judging by what ive seen I wouldn't doubt it.

    I don't see anything that alarming yet. water spots like I have seen many times, but I dont see the rust you are talking about.

    did you see the first post the pics I added? im comparing this crank to my old one. my old one has no rust its all grey. this one has rust, in spots all over. the collars that sit in the case and have the bearings in them also are visibly covered in orange splotches. I cant get a pic cuz its so hard to see its a tight space. id love nothing more than to hear its ok to use but I just dont feel like its right?

    Looks exactly like my crank too.. You are good to go man.. Keep in mind not every crankshaft is going to look exactly the same.. They can be manufactured at different facilities using slightly different processes and they are not all built at the same time within the same batch.. Cranks are gonna differ from one another bottom line.. Plus IT'S A WATERCRAFT! No matter what you do you are prone to moisture.. You will get moisture in your engine no matter what.. That moisture sits in your hull and engine while not being ridden.. Then the next time you crank it and ride it, the moisture burns off and you are left with slight discolorations in areas.. Just the way it is..

    Thanks for the input guys, I took the crank out today.. with a flashlight I can CLEARLY see rust in every single journal where the bearings ride. I can roll the bearings and watch them pass right over rust. its on every single one.

    What should I do here? from what I was told any rust where bearings ride is a no no and every bearing race is rusted.

    Depends on the damage it did.
    try WD40 or IMAL and let it sit for a night, turn the crank, and see if you can get it off.
    if its in deeper, its a no-no-no-no
