Is there a way to tell on a Johnson, by the model number if it's a long or short shaft motor???? I see there's 20R70 and I see there was a 20RL70 I assume the 20RL70 is a long shaft???<br /><br />I'm asking because I have found a couple of motors a little distance away and the guys are sure if they are long or short shaft...

Yes, Bunky.<br /><br />The 20R70 is a recoil start, short shaft engine and the 20RL70 is a recoil start, long shaft engine.<br /><br />Good luck. :)

Probably a short shaft, but ask them to measure where the motor bracket sits on the boat to the cavitation plate and that will give you the answer. Like this: Send them this pic if you a corresponding by E-mail or if they have internet access.<br /><br />

As JB confirmed. Thought it was a short shaft, but I thought I would throw that in...

I have 2 motors and both of them measure 18inches from the top of the transom to the top of the cavity plate..<br /><br />My understanding is that the 15 inches for short shaft is the transom height ....

18" is considered a short shaft, even though it's a little longer. Some made them that way... E or EL stands for electric start...
