I looked at the catalog link posted above. The 1970's had a slightly different upholstery, and the 71's didn't offer that color. My guess is its a 72.Your motor probably doesn't have power trim. So, set the trim rod for optimum performance, and then tilt it by hand.I actually really like it, if I can prove to the state of Michigan thst it is worth less than 2500, I will be able to get my own title. FO You Think It's A 71?
You have to either hang out the back of the boat or get out. The trim pin is moved by trial and error several times. Once you find the sweet spot you like it stays there forever and you live with compromise position. When you tilt the motor to beach the boat or put it back on the trailer you grasp the top of the cowl, grunt and groan and pull the motor up.I have never adjusted trim by hand, is that something I can do while its in the water, or just on land?
