    1986 mercury 115 2 stroke inline 6 bogging at full throttle

    Well finally got the new fuel line on and got a chance to take the boat to the lake and it ran like new. Did great, the old fuel line after 11 years had deteriorated on the inside and was plugging up the fuel line. Thanks for all the feedback lotsa help. Everybody on this forum is always helpful...

    1986 mercury 115 2 stroke inline 6 bogging at full throttle

    took off the old fuel filter and it looked good a few small spec in the bottom but the screen was clear and was not restricting fuel flow. I'll put on the new fuel filter and new fuel hose tomorrow and prob pull the pickup tube and check the strainer.

    1986 mercury 115 2 stroke inline 6 bogging at full throttle

    Took off the fuel filter and cut it open. It looked pretty good a few little dark specs in the bottom but the screen inside was clear and looked good.

    I've ordered 5/16 and 3/8 fuel line should be here Thursday. If the 3/8 fits the fittings ok think I'll go with that.

    Should have thought about squeezing the bulb and seeing if that helped. I'll replace the fuel filter and take a look at it. Thanks.

    1986 mercury 115 2 stroke inline 6 bogging at full throttle

    I couldn't get a very good picture but the goop inside the line is the lining thats in side the fuel line . It looks like it has a inner plastic lining in the fuel line. When I cut the plugged up part off and pushed the fitting back in the line the inner liner just bunched up inside the line and...

    1986 mercury 115 2 stroke inline 6 bogging at full throttle

    Its permanent. Checking the strainer sounds like a good idea if I can get to it. I didn't think of it while I was at the lake but I probably should have hit the enricher while it was bogging and see if it picked up Then I would know its a fuel issue.

    1986 mercury 115 2 stroke inline 6 bogging at full throttle

    Motor was rebuilt in 2012 with all new pistons and has very few hours on it since. I just replaced the water pump impeller. I don't believe there is an overheat horn, the boat didn't come with a temp gauge. The marina that rebuilt it in 2012 replaced the fuel line with the sierra silverado fuel...

    1986 mercury 115 2 stroke inline 6 bogging at full throttle

    My 86 mercury 115 runs great for about 30seconds out of the hole then it boggs down and will only run about 3000 rpm and will surge some. Go back down on the throttle and wait a bit and it will do it again. It seems to me the fuel delivery is not keeping up with the demand and once it sucks the...

    Inline 6 Sound Blanket

    I'm going to repost this question as I should have titled my 2 threads differently as it is too confusing. Does anybody know did my 1986 115hp come with a sound blanket inside the cowling? Where I might find one? Or could I make one?

    1986 115hp inline 6

    Well its good to know its most likely not the reed valves. Yes he rebuilt the carbs and fuel pump replaced the stator and the fuel hose. Of course this was all done in 2012 so its been 11 years but it always been a problem. I've always had to goose the throttle a little every time I put it in...

    1986 115hp inline 6

    Well in 2012 I burnt the motor up the first time I took it to the lake. I found out why you don't trust the old auto blend systems. I knew nothing about boats it was the first one I had ever had. So a local marina rebuilt it for me all new pistons ect. But he didn't change the reed valves and...

    1986 115hp inline 6

    Yes I've had the motor since 2012 and have a new impeller ready to install soon. I didn't think it would make it run hot but just wanted to hear another opinion on it. I didn't want to burn it up (again). I might see if I can find one of those sound blankets as it is just too loud for me as is.

    Is there an easy way to replace the reeds on this motor? Or is there no other way short of taking the entire engine apart?

    1986 115hp inline 6

    After owning this motor for awhile now I have come to the conclusion that it is very loud. I have seen some cowls that have what appears to be an insulated hood I'm assuming for the purpose of cutting down on the noise. My 86' doe not have this insulation. Would it be ok to install one on my or...
