Hi again , my down season is approaching so i am gearing to work on the treasure I gathered in the summer. Not much work for gardeners up here in winter. I have a '57 johnson RDE-19 239513. I paid $90 at a yard sale at my church with 3 pressure tanks and a good paddle. In very clean condition, with all controls ( rubber somewhat rodent damaged). I also got a motor given to me, the tag says RD-17S, it has been repainted and a 30 painted on the cover, it is seized and I don't mean gently, it has had water in the power head and froze and broke stuff from the inside out , so I think the power head is toast. However it is a long shaft, i would like to make the RDE-19 a long shaft motor as my transom is 21". So my question is, first, just what is the RD-17 S 1300228,, i cannot find it under any list for 35 HP that i have, or under 30 HP either. Is it a 25HP? and if so can i use the spacer and other things that make the motor a longshaft? Thanks guys, I have had great luck in gathering older motors this summer, people tired of tripping over them i guess. I got a couple for the price of the scrap. see ya soon,,,dave
