i have an evinrude 85 starflite, 1974 model.the tilt/trim pump motor is bad.i have been told that the company that made that motor has went out of business, & parts are hard to find. i would like to know where i can find one of these,or if there are any other motors that used this type that would interchange.the pump motor and pump are inline in the same case, and mounted outside the hull.thank you for any help you can give!
