  • A quick video on Distributor issues. Special thanks to the Facebook Group Inline Enthusiasts!!!! Matt, Daryl, and Tristan!!! Outboard was running extremely bad.... Jeff from Tennessee hooked me up with a beautiful 1400/1500! Special Thanks to him for being true and absolute!!! Back to to the intermittent firing, backfires, and overall rough idle..... Will I figure it out????? Watch and see!!! As always, thank you for watching!!!!! Son

    Hey man, how do i go about decoding the serial number or dating one of these motors? I "revived" and sold an 800 and just picked up a 1000. Im loving these big old Mercurys, ill be following your channel. Thanks man

      Need a service manual. I believe the 1000s were circa 1968 if my memory serves correct. I could be wrong. Son

    Hey, I saw your eBay post for the Mercury 140hp. I can pick it up in person, I’m in MD. But are you willing to negotiate price? It doesn’t have that option.

    Hello son love your vids my brown and white wires burned in two ( completely destroyed) on my switch box any ideas on what can cause that before it ran great 👍 it’s a 1975 850

    Enjoying your videos. I have a mid 80s 115 ran great but wasn’t peeing;replaced impeller and right before I finished up I checked carbs and noticed it was leaking when priming. Last owner never replaced float bowl gaskets after taking it apart. Fixed that. Washed engine bay, Now it will not accelerate. Runs great at idle but will not get over 5-10 mph without flooding itself. Any help is appreciated.

      Thanks. Figured out it was the spring that popped off in the top throttle adjuster “thing” lol. The previous owner had the spring upside down (I believe) do you happen to have a video or picture of one of these getting put together. . It has the linkage going to the stator

      @MerCSonL6 the motor is a early 70's 80hp model 800. I've rebuilt the carbs and fuel pump, compression was mid in spec with 2-4 psi between cylinders. I have not touched Timing. And I feel like your going to say to check spark and timing bobbles down low and will idle at about 800rpms no less. Sometimes dies when put into gear. Sometimes it runs okay when put into, wot runs great.

    slt sound, I have a 79 l6 with remote trim pump and I would like to know if you have the adjustment of Valve Body & Gear Assembly 392-7734. because my trim no longer goes down. thank you so much for all the videos. A great help. Thanks.

    Hi I have a 1989 115 mercury 4 cylinder outboard.2x2 it starts and runs but misfires at idle on one cylinder, I have replaced the coils the cdi and the HT leads, Would a bad trigger cause this issue, Hope you can help

    • @MerCSonL6
      @MerCSonL6  Před 10 měsíci +1

      There's a multitude of reasons. But the trigger is a great place to start. I have a video on how to test without removing. Son

      @geraldoakley7688 Před 10 měsíci +1

      Hi thanks for the reply. I have done the test on the trigger and it's all in spec. So I am thinking it's the stator as I am getting no reading between the wires, I have ordered a new one from CDI. One quick question does it matter which terminals the yellow wires go to from the stator as they are both solid yellow @@MerCSonL6
