I did know the answer to this, but for some reason my brain has lost it! On tiller steer mercs, how can you tell the difference between a short and long shaft? I dont remember if the lower unit is longer or not. If so, what is the measurement on short shafts, and also long shafts? Thanks a million in advance for your help.

Re: REALLY dumb mercury question

Measure from where your transom top would hit in the engine mount, to center line of the prop shaft. should be 15 inches for short shaft, 20 inches for long shaft and 25 inches for extra long shaft.
