    EFI Fuel injector info needed:

    I haven`t seen to much about the fuel injectors in posts relating to:
    how many hours are they good for?
    if hours are translated into miles you would think they should last a long time...
    I almost never see them in the classifieds, what are a good used low hour set worth? and how would you tell they are low hour?
    I know injectors can be sent to "injector-rehab" for a good cleaning. why and when should this be done?
    comparing the gpr injectors to other applications they seem to be the most expensive by a lot.

    if using pump gas from land stations only, and having 100+ hours on injectors how are these any different from the automotive injectors that run for thousands of miles without issue...

    so just trying to understand, why and when service should be done.
    obviously if the machine is running rough and all test show the injectors are the issue, then I could see a new set or having stock one checked out...
    What can you people say?

    I was only around 100 hours when I had my engine problems last year. Turned out to be a clogged injector. Probably from fueling up on the water so much.

    Andy check out injector rehab. It didn't cost much to get the 3 injectors cleaned and they have a quick turn around.

    After they do them they provide you with a graph showing before and after results from the injectors

    was the failure from an injector, or was the ski sunk that caused issues?

    Good one but nope

    Turned out my injector for cylinder 2 was clogged and cause the ski to lean out and costing me a head and a cylinder.

    The ski did have a water line come off 2 years ago

    A biz called Midwest fuel injection can clean and flow test them for you, look them up on the web.....The injectors themselves are the same as automotive injectors...I am having mine cleaned this winter with 100 hrs...they clog up on cars so naturally the can clog up on our skis too..with your new crank and top end, it would be best to start fresh every else too....you are already in it this deep.
