    Bubba or anyone else know if this motor has the pee hole or a tell tell. I don't see one anywhere. Model #6428633. I don't have a problem changing the pump but how will I know it's pumping. I pulled a small pipe plug out of the top of the head and it puts out a good stream there. It gets stronger with increased rpms and is warm at idle.

    It should have a tell tell on it. Look for a small rubber tube running out the bottom of the cowling where the motor sets. If it doesn't have one take the plug out and get a 1/8 npt nipple with a barbed end and add you a tell tell. If you have one it may be stopped up from various critters that like to make their home in that little dark tube.:big_smile:
