Another trim unit question.

[CaptainPuget]

Are 3cylinder and V-4 trim units interchangeable? I’ve been looking on ebay for a tilt/trim unit for a 1980 70hp Johnson. Some sellers claim that their units off a V-4 will fit, others say it won’t. Both the 3 cyl & V-4 units appear to attach with 6 bolts, what’s the difference in them?

The PTT assembly on a 1980 70hp Johnson/Evinrude with a 20" shaft is the same PTT unit as on any of the 1980 v4 units.<br /><br />Any difference between the two (3cyl/4cyl) would come into play ONLY if the 1980 70hp was a 15" shaft model. The 15" shaft 3 cylinder model has different type transom brackets etc whereas it requires the older style PTT unit that has the lift cylinders on the outside portion of the transom brackets.

Thanks Joe, that’s exactly what I needed to know. Your information is always right on the mark.
