    Not for V/P XDP

    Satisfactory product if the threaded metal shaft were long enough to fit the recessed V/P XDP outdrive oil drain hole.

        Higher horsepower Hondas need adaptor

        By Greg

        Comments about Lower Unit Quart Pump & Lube Tube:

        The packaging states that adaoptor Model 8704756 is needed for Honda 2-50hp models; however, I found that my 130hp Honda BF130A also required the adaptor.

          Comments about Lower Unit Quart Pump & Lube Tube:

          Perfect tool for the job. Used it to fill my alpha one stern drive. No adapter was needed. The filler tube on the end of the pump needs a hose clamp. It fell off once while I was filling my stern drive.

            Comments about Lower Unit Quart Pump & Lube Tube:

            Product works very well and appears to be of sound construction. The pumping mechanism should last at least several changes before needing replacement.

            You will get your workout by pumping two quarts of oil upward into the lower unit. Make sure you have towels handy for any leakage.

                    This pump does not come with the adapters you need to fit most lower units. Check on the size you need. They do sell them seperatly.
