I have a 65 horse jet mercury out boatboard which is beyond repairing the top end. Does anyone know what size options I have to install the lower jet unit (shoe and foot assembly) onto. Looking to find another power plant and just curious if it has to be the exact or if I have options in my search. Thank you for your time and expertise.
