hello all, i just purchased a 1998 wellcraft with a evinrude 50 spl. the motor does not have trim and tilt on it. you have to manually lift the motor and lock it. it has a cylinder and a housing unit beside it that has a line coming from it to a switch on the side of the transom mount to stop the hydrolic pressure. can anyone help me to understand what i need to do to get hydrolic or electric trim please? sorry i dont have a picture of it but i hope someone can help me. thank you in advance.
