    v4 crossflow bubbleback: looking at a thermostat job: what to order?

    Re: v4 crossflow bubbleback: looking at a thermostat job: what to order? Do you have a picture without the duct tape, so we can see the cutout size? Do you have a picture of the completed job using rivets or whatever you ended up doing?

    Joe Reeves Timing Method & the Throttle Cable

    The Joe Reeves Maximum Spark Advance timing method below does not mention if the throttle cable is disconnected. I saw another thread that said the shift cable is disconnected (which makes sense), however, nowhere do I see any mention of removing the throttle cable. The reason I ask is because I...

    In testing a 1990 Johnson 115 that I bought recently, I ran the engine three minutes or so at idle with a Temperature Gun Infrared Thermometer W/Laser Sight and got 183 degrees maximum on port side and 104 on the port. I decided to replace the thermostat, and went at today in the evening and am...

    Flushing Engine with Citric Acid

    Mercedes Benz flushes it's aluminum radiators and engines with citric acid. I believe they remove thermostat and pour 12% citric acid granules which is first dissolved into sufficient water to fill the radiator. The engine is run for x minutes, and then flushed out with fresh water. I can...

    Johnson 115 1990 - water temp gauge goes where?

    Re: Johnson 115 1990 - water temp gauge goes where? Found this water flow chart in the manual: The water flows up the middle of both heads and out down the outsides. I think this means that the thermostat housing has incoming ocean/lake cool water flowing through it, and the hottest water...

    Adjusting Maximum Spark Advance Without a Test Tank?

    I need to check the maximum spark advance on my just bought used 1990 Johnson 115. I don't have a test prop (I need #382861), and I don't have a test tank. The only way to do it that I can think, is to have a driver run it on an open flat calm area while I do the timing light. However, my timing...

    1990 115 Johnson- carb rebuild- how tight is tight?

    In rebuilding my two carbs on a Johnson 115, there are 6 screws on the top idle channel gasket #6, if I tighten them all the way, I can see the gasket folding in the open spot in the middle, in the top H opening. Am I supposed to tighten the screws till they are as tight as they can get? It...

    Johnson 115 1990 - water temp gauge goes where?

    I want to install a water temperature gauge on a 1990 Johnson 115 I just bought. Where does the sender tap into? I don't see any threads for a sender. What kind of sender does it use, in the water or touching the outside? (PS- I'm also going to install a water pressure gauge, which I'll just...

    Recirculation System Servicing 1990 115 Johnson

    Re: Recirculation System Servicing 1990 115 Johnson OK, now I understand, for all who read this in the future, here is the bottom line: There are 4 check valves below the carbs, and none at the bypass cover, or the center main bearing. All four check valves are identical and all four flow out...

    1990 115 Johnson - Carb rebuild - Should I Remove Lead Shot?

    I'm going to rebuild the carbs on my 1990 Johnson 115 that I just bought used. Should I remove the lead shot on each carb? Can clogging dirt get behind there? I don't see much mention of removing it in YouTube videos. The parts kit from OMC does not include it as far as I know (have not received...

    Recirculation System Servicing 1990 115 Johnson

    Re: Recirculation System Servicing 1990 115 Johnson From the manual: I think the pictures in the Recirculation System Servicing instructions in the manual page 2-29 are wrong (see my initial posting). Nothing makes sense, I'm left with some check valves which I don't have a clue which way...

    Re: Recirculation System Servicing 1990 115 Johnson To add to my confusion, here is a picture of the intake manifold with the hoses marked in red. Notice that the manual calls #2 location the bypass cover hose fitting, yet the picture #2 is not of the Bypass cover location, it is the center...

    Recirculation System Servicing 1990 115 Johnson

    Here is the page about the Recirculation System Servicing from the 1990 OMC Johnson Evinrude manual for my 1990 115 Johnson. In this page they are testing two different one way valves: #1 they call the recirculation check valve, and it's supposed to flow ONLY out towards the barb #2 they call...

    Binnacle Mount Remote Control Mounted Wrong?

    I just bought a used 1990 115 Johnson that won't go past 2000 rpm (estimated. It has no tach). I looked at the cables and found that the stroke of the throttle cable is only 2", therefore, the engine throttle is not able to travel all the way to full speed. The shifter cable on the other hand...
