    High Idle, throttle adjustment?

    I recently rebuilt my carbs and completed a lync and sync after installation. I made sure all of the butterflys were closed and checked timing etc. Now i am having idle issues, idling around 1000-1100 out of gear. I can lower it by adjusting the throttle cable and allowing the distributor to...

    78 mercury 115

    I am running a 1978 inline 6 116 on a 16 ft runabout with a 19 pitch prop. I am having issues with the motor bogging down, only when it is hot outside (90 degrees plus) and the water temp is warm (80 plus). I took the boat out a month a ago and it ran great, maybe bogging once in a two hour...

    79 Merc 115

    Just wondering, does the 70 model have actual reed valves or rotary valves? Last time i took the carbs off i could swear it had rotary valves. I am asking out of curiosity. But this motor runs off and on all day. I have literally done everything except a linc and sync procedure: carbs rebuilt...

    78' 115

    Hello, I own a 78 mercury inline 6 115hp. I am having problems trying to solve my "bogging" problem. Last season i chased the problem for months. This season the boat is acting funny again. Every so often, the motor will bog down and struggle to plain, but will take off like a rocket at...

    stator 79 inline 6

    Trying to check the stator on my 79' inline 6. Pulled the wires and checked the ohms, came to be about .5 between the yellow and yellow/red wire. I was considering getting a new one anyhow. Anyone know of a good place? Maybe boat fix for $130? Also does anyone know the part number without...

    merc 115 inline 6

    79' inline 6 115. Took the boat out this morning expecting a good trip. Last week i thought i had my problems solved however i obviosly didn't. Putted out and fouled a little but cleared out and ran pretty good. Then i went to ski. The motor bogged down and wouldn't go. Cleared it out, same...

    79' inline 6 carbs

    My 115 is leaking through the carbs. I just put in new needle and seats and new floats into my carbs and adjusted the arms to merc specs ( 13/32 upside down and a 1/4 hang) However, when i squeeze the bulb really really hard, fuel still comes out throught the carbs, thus through the needle and...

    115 inline 6 fouling 1 and 2 plugs

    Hello, just continuing a recent topic. My 78' 115 is fouling the number 1 and two plugs, top carb. I have removed the bowl cover and checked the float, needle and bowl walls, all seems fine. However, my plugs are fouling out within two to three hours of use, and show signs well before that. I...

    78' merc inline 6 115

    Hello, I have a 78' mercury inline 6 115. This boat runs great with new plugs, a true monster. However, after only a few hours of running, such as two 2 hour trips, the plugs begin to foul and the boat stuters and fouls when trying to plane out, obviously not allowing me to plane. I have...

    79' 115 inline 6

    I just recently finished a basic rebuild of all engine components over the spring. The boat would run amazingly well for several hours then just stop idling almost altogether, well, the floats were sinking. So i replaced the floats and now the motor will not start without a little throttle. I...

    78' inline 6 carbs

    would it be okay to leave the plastic arms connecting the butterflies on while soaking the carbs in a carb cleaner (from the early 80's). I did a test however i forgot to completly inspect the platic before i put it in so i could not come up with a conclusion. <br />Thanks,<br />Dassault

    79' Mercury 115

    I have a 1979 merc 115 outboard. I use the boat for skiing only. The boat does great most of the time during the wholeshot. But a good 50% of the time the engine will hesitate or miss. I have adjusted the idle mixture numerous times. I replaced the ball and pump diaphragm, but i did not...
