    Default 25hp Nissan prop doesn't turn and water pump will not pump

    I've meesed with outboards a while this is the first I've seen where both prop and water pump don't work. I assume it is drive shaft related. Just quit working will motoring no other symptoms. Motor still idles fine.

    What is your model? If you drop the LU, is the driveshaft in one piece?

    The two things are independent of each other. So, unless you have a broken drive shaft, the problems are not related.

    My answers are like Zen...It may not be the answer you want, but it is generally the answer you need.

    The 3 Rules:

    1) Look in your service manual first...Then ask me if it is correct.
    2) Understand that your desire to repair your engine does not mean that you have the ability to do so.
    3) If you are confused, take your engine into a dealer..Then let them be confused...At least, in theory, they sent someone to outboard 101.

    Are you saying the top end of the driveshaft doesn't have splines? If so, it is probably snapped off, with the splined portion stuck in the crankshaft.
