    Mercury 115 fuel bleed system

    Well then you have schooled me on yet another misconception of mine. I knew that on my Mercury motor I was only changing the idle timing to adjust my idle, but for some reason I thought that was unique to the 2+2 design. I had thought on my other motors that the timing screw on the tower shaft...

    Mercury 115 fuel bleed system

    I was not aware of that, and you make a very very valid point. The answer to your question is “no idea”, now that you ask. I had been assuming that all collected bleeder fuel was directed to that lower end cap, by gravity or otherwise, and then that the external bleed hose was under vacuum of...

    Mercury 115 fuel bleed system

    Faztbullet, it’s way too late to worry about the length of the rabbit hole. Fuel filters, carb kits and main jets, stator and trigger, regulator/rectifier, switch box, accelerator pump rebuild with check valves, fuel pump rebuild, then the exhaust gaskets project…I love bolting on those new...

    Mercury 115 fuel bleed system

    The idle timing has been set during the link and sync procedure many times, always just in the driveway on muffs or I also have a tank that I run in occasionally. Always start out at 2 degrees BTDC. Not sure how Fitz 1995 motors are but my motor idle is set by adjusting the idle timing...

    Mercury 115 fuel bleed system

    I’m not sure I’m qualified to convince myself the bleed valves are bad, but I do find it odd that I can put a barbed nipple in the lower bearing end cap with a length of 1/8” hose on it and blow through my motor. Seems to me if there are three check valves in there working right I would not be...

    Mercury 115 fuel bleed system

    Your suggestion is correct if you are one of the lucky ones with what the service manual refers to as Design 3. Those motors have a check valve and carrier accessible behind the reed block and replaceable without splitting crankcase halves. Designs 1 and 2 both require removal of the powerhead...

    Mercury 115 fuel bleed system

    Not sure if I used the proper reply method last night, trying again this morning. The compression readings are cylinder #1 138 psi, #2 137 psi, #3 136 psi, #4 130 psi. My notes on that test are dated October 9 from last fall so they are current considering the boat has been out of the water for...

    Mercury 115 fuel bleed system

    Not sure if I responded properly within the forum format last night as a new member that’s bad with electronic devices. Sorry for doubling up with info.. The stator is new as of last summer with limited hours on it, CDI electronics brand. I do have a DVA adapter, I will do my best to double...

    Mercury 115 fuel bleed system

    Racerone, my compression test dated 10/9/22 was cylinder #1 138 psi, cylinder #2 137 psi, cylinder #3 136 psi, and cylinder #4 130 psi. Fitz, the stator is new and is CDI electronics brand which I believe is a decent quality aftermarket product. I do have a DVA (also CDI brand) but not much...

    Mercury 115 fuel bleed system

    I have a 1991 Mercury 115 (2+2) outboard that has symptoms that led me to attempt troubleshooting the fuel bleed system. My model, unfortunately, is one of a chosen few for that era that have the bleeder system check valves installed on the interior of the crankcase cover in the vicinity of the...
