Re: '72' Johnson 25 SeaHorse
Hi Capt TaJL<br /><br />Welcome to the list..<br /><br />I don't know your specific motor but I had a problem with my old OMC, where it would be crusing along at WOT and suddenly it would be screaming in neutral,,, and if I lowered the rpm right down, it would engage again..<br /><br />In my case, I had a selectric gearcase, and the forward clutch was worn.. I took it apart and swapped the forward and reverse gears around.. they were the same and it wasn't that difficult a job..<br /><br />However, that was an older motor then you have.. and a 72 probably had a hydro electric? (or maybe the smaller OMC's of that era had mechanical linkages??? I don't know... does it say selectric or hydro electric on the controller or anywhere else??)<br /><br />If its a hydro electric, then you have either a clogged oil pump in the gearcase or something weird happening with your electrics or soleniods..<br /><br />If I knew what type you had, I could probably make some better suggestions.. (then again, there are probably people on this list that will know the motor off the top of their heads..)<br /><br />as for your low rpm backfire.. you should clean the carbs.. check your plugs.. and get used to how the choke and stuff works on your motor.. these things never run perfectly smoothly at low rpm.. thats a trait of old carb two strokes.. but with judious use of your choke and stuff, you can minimise the problem.<br /><br />Also, if you just got this thing, have you checked the impeller??? <br /><br />you should get a manual, it will help you no end.<br /><br />regards<br /><br />Frank
