    Water temp or head temp?

    So I got that dual-temp gauge from a company I won't provide with a free advertizement. Put the sensors into water pressure ports. Works acceptably well showing cooling water temps. Apparently, the motor (j115plsor) has a blind hole in each head that also looks like 1/8 NPT. I wonder if that's...

    2005 J115PLSOR weird oil leak

    Where is that stuff possibly coming from? Fuel system is tight all the way up to carbs, floats set right (I think - manual calls for 1 1/16...1 1/8in or 17... 28 mm (sic) drop). Does not look like fresh fuel anyway; more like 2-stroke like mix that's been sitting for a while. Thoughts? Thank y'all!

    2005 J115PLSOR intake overpressure/raw gas?

    OK... saga continues. New powerhead, redone carbs. Engine sneezes at idle, crossflow line come off fittings (at green arrow, view from starboard), and a spray of fuel comes out of the line. Can't think of anything other than excessive intake pressure, and don't see any way for that to happen...

    2005 115 Johnson PLSOR dies at idle

    Alright, after sorting out earlier problems with the project (dying when throttling up - don't ask me how, it just started running OK after unscrewing and blowing out the jets for the nth time), here's another: dies at idle. Starts OK, idles for a few seconds at about 700-800 rpm, then sort of...

    2005 115 Johnson PLSOR fffffffffrustration... (still dies off idle)

    So I am still trying to find out what my problem is: it almost feels like the motor is fuel starved AND runs rich at the same time. Starts fine, but when you give it throttle, sputters and dies. So far: Carbs rebuilt (gaskets, needles and seats) + new bowls (jets moved from old). Hope I did not...

    2005 115 Johnson PLSOR dies off idle

    More trouble with the project. Took it out again. After about 15 minute WOT run and maybe 30 minutes of fishing, start again. Starts easily, but if I give it gas, dies quickly. Or may die while idling for no obvious reason; almost feels like it is fuel starved. Pumping the primer bulb does not...

    2005 115 Johnson PLSOR carb floods for no apparent reason

    Tried the project on the water. After about 10 minutes of around idle RPM, give it some gas, motor sputters and dies, strong gas smell, primer bulb limp. Pop airbox, pump primer - there is a gas fountain in the throat of starboard top carb. Pull the carb, remove the float/needle - everything...

    2005 115 Johnson PLSOR: how hot is too hot, and how much clunk is too much?

    More (small) troubles with rebuild project. The shifter cable was pretty frayed (jacket was literally coming apart); had trouble finding neutral. Replaced, shifts nicely now, but the CLUNK! when clutch engages seems louder than it was. RPMs are around 600-700 (same as before). I realize after...

    2005 Johnson 115 minor annoyance this time

    When I trim the engine in, engine comes to a stop, but the trim motor keeps running until I release the button. Faulty switch? Where do I look for it? Come to think about it, the boat did not come with a trim angle gauge. Is there a way to hook up an aftermarket one? I suspect the sender is...

    2005 Johnson 115 with low compression: noob seeking wisdom

    Here is that 2005 2-stroke 115hp Johnson (PLSOR) that I am goofing around with. Compression seems consistently low (90 psi +/- in all 4 cylinders), but starts/idles/runs OK. Any thoughts on how to proceed? Leave it be and deal with it when real trouble starts? Tear down and rebuild now...
