1956 Johnson 30hp

Hey guys , me again . Where do you measure to get the shaft length ? I measured from the cavitation plate to the bottom of the engine pan and got roughly 21" . Is this a long shaft , and if so does any of you know where I can get a short shaft? As always , thanks . Jeff

Measure from the anti-ventilation plate to the inside top of transom bracket.

I get 18" to the top of where the motor pivots .

Measure from anti cavitation plate to the part<br />of the mounting clamp that rests on the top of the transom. Short shaft approx. 15 inches<br /> long shaft approx 20 inches. On these motors it is easy to spot a long shaft there is a 5 inch<br />extention very obvious in the lower part of the<br />leg.

My Johnson 28 also measures 18" here, but is listed as 15" shaft. I *think* it is to make sure the unsealed plate covering the water passage on the side just above the cavitation plate stays submerged. Does anyone know if there is a problem raising this engine 2-3"? What if you seal the plate?

I'm coming up w/ 18 1/2 " but I do have the 5" extention your talking about . Does anyone have a short shaft set-up they want to get rid of ? Thanks , Jeff
