I have a problen w/ the 1986 johnson 60 on my 15 ft s.s. Last weekend I was out and after about 15 min of running steam was coming out of the "pee hole" of the engine. When I would put it in nutral week water flow would return. So I figured bad water pump. I replaced water pump and have very strong flow when running on a hose. I go out again run the boat for 15 min. and the same thing happens. The only diffrence is I have a strong flow when I put it in nutral. It is acting like the thermostat is not opening but there is no thermostat on this engine, if I am reading the manual corectly this is getting to be very fustrating. I would realy apreciate any advice someone is willing to give. Thanks in advance.

Reeltime, I'm pretty sure that your 60 would have a thermostat. Look into it a little further. I would try to locate the thermostat and replace it. It is good preventative maintenance to change the thermostat when you change the impeller on the pump. Depending on your conditions, this should be about every 2 years. Cheaper to do this than to replace a burned up powerhead. Not to mention the aggravation. Occasionally you can get something in the outflow to block the flow, or slow it down. If you run in saltwater you can get a buildup of salt crystals, or sometimes there can be mud in there, or a bug will make a nest. You could try to push a soft wire up thru the peehole to see if there is anything in there. The nylon line from a weed wacker works good too. If none of this helps, and if no one else on this board can help, I would suggest that you go to:
www.wmi.org/www/boating/boatboard/index.html
Post your question there for Dunk or Sal. They are very OMC savy.
Hope this helps

Reeltime -
Do you run in a shallow area, especially where there is a sandy bottom?
Reason I asked, is that a friend of mine was experiencing the same type of problem. What he found was that a considerable amount of sand had been sucked into the water cooling system chambers. I think he mentioned having over a cupfull of sand come out.

Don,
No it has not been in shallow water I only use it for offshore fishing here in south florida. But the pick up screen was broken when I got it. I just replaced the screen when I changed the pump. My first thoughts also were, something is stuck in the power head. I called the dealer today and there is a thrmostat. I am going to replace it this week.
Thanks,
Rick

Reeltime, let us know when you have the problem solved, and what the remedy was.

Hey guys. I figured it out. I found the thermostat housing removed the thermostat, and it was totaly cloged w/ seaweed and just about every thing else you can think of. There were two pressure relese valves next to the thermostat. The thermostat was holding water in the head then when it would heat up the pressure relese valve would open thats why I was getting bursts of steam.
Thanks alot for all of your help,
Rick
