I have several 46-47 Evenrude outboards here, [two Sportsman models, one 4409 and one 4416 and a Zephyr 4404] . They all came with 1/4 x 20 bolts in place of the tilt adjustment pins . I would like to reverse engineer something closer to what was original but am having problems finding pictures/ drawings of what was factory. Anyone have a picture of the right replacement?
