I need to find the engine specs for a 4HP Johnson? Model# J4RSSM. I'm looking to buy it used? The current owner picked it up at a yard sale and knows nothing about it. I haven't seen this motor yet. Is this a 2-stroke or 4-stroke? Short or long shaft? Internal or external tank? 2 or 1 cyclinders? Approximate weight? I'm guessing, but I think it's 2000> model with a 15" short shaft.
