The motor ran fine about 2 weeks ago. 2 days ago I had a hard time keeping it running, checked the gas and it looked like coffee add 2 creamers. So I ditched all the gas and started fresh with some sea foam in it with a 50:1 oil mix. After that it would star and run but idle pretty high I would say around 3k - 4k maybe more. It would idle fine if I pushed back the timing plate with my thumb (Keeping a close eye on the flywheel as to not lose a finger.) But I couldn't quite understand how this problem would just arrive from a 2 week sit with dry carbs. So while I was looking around. The motor stopped pumping water right in front of my eyes, as to say... "screw you" So I changed the water pump... then went back to the original high idle problem. Like I said I was hesitant to adjust anything but I found if I would idle up the throttle it would stick at the higher RPM until I reached back and physically reset the throttle by hand.

Onto the best part... about 15 mins ago... maybe 30. I was running the motor in a drum and decided to see how the RPM's would react with a little back pressure. I started the motor, popped it in gear, and in return the foot smashed a gear into 5 pieces and blew a hole in my foot about the size of a 50 cent piece. It was not idling high when I put it in gear. I know that shifting at high RPM's can do exactly what I am describing but you are just going to have to trust me on this one... So when its all said in done, in 2 hellish days I went from owning a nice fishing rig to having absolutely nothing.

While I search for a new lower unit I would like to take the time to fix the idle issue. I'm not going to lie, it does not even seem worth it at this point. But the motor has treated me well for years... If I could cry I would. I can see my craigslist ad now... Johnson Outboard, idles a little high, leaks a little oil from the foot. lol. :facepalm:

And I'm new here, frustrated, depressed and lost. So take it easy on me.

If it was myself due to the age of the mtr ( 28 yrs ) and the probs it has, I'd look for something different and just part that one out.

You must have me confused with someone that can afford to part out a motor and buy a new one. Or a new used one. Haha. Oh well, so long water time to squeeze in on the public pier like the poor white trash I am. At least I can say I was never taken by Davy Jones.

You can part it out and save up over the winter for a used motor.

It's the thought that counts Scott. You are a true gentleman and should always be blessed by life. I really do appreciate the thought.

I still may need some help with the idle issue. I have seemed to got it right on muffs but I wont know for sure until it hits the water. It may bog, who knows.

Once you go through the process of checking compression, proper spark, and cleaning out the carbs, then get a hold of me. Chances are that after doing that it will run fine, however if it doesn't then let me know on the thread here and we should be able to get ya fixed up.
