I have a '70's 35 hp Johnson short shaft electric start motor with no plate on it. The number on the freeze plug is 392124 RPH. Can anyone identify model and year<br /><br />There is some black oil coming from around the prop. <br />Is this something to be concerned about?<br /><br />Thanks

Welcome to Iboats, Nmayo!<br /><br />RPH in the freeze plug number means "Replaced Power Head" so that tells us nothing. Is it possbile to post a picture or two of it? Try to get a picture of the cowl and ignition system since those really help dating them.<br /><br />Black oil around the prop is normally just unburnt fuel/oil coming from the exhuast. Take a sample and smell it. If it smells of gasoline, that's all it is. If it's got a sulferish smell, it could conceivably be lower unit fluid.

Thanks Paul, I will send you picture by email as I haven't figured out how to do it on this site.
