My outboard mercury motor was running rough, between 1000 rpm to 4500 rpm and sometimes over that. I looked into cleaning carburators, changing spark plugs etc. I changed inline fuel filter and fuel/water seperator, added stabilizer, still no luck. A certified marine mechanic, changed stator that cost me $830. Still issue was there. Then I found an online video that had issue like me, his issue was the trigger. I purchaed the trigger on amazon, it took me 30 min to do the job and now my boat runs great. I have listed links below that may be useful to you. Please like and subscribe, it encourages me to post more videos. Thanks!!

Nice job, I would recommend that everyone with similar problems to order a Mercury service manual from a Mercury dealer, it inlcudes all the test and steps to diagnose issues with your motor. Its very detailed and easy to follow. Mine has a similar issue and the resistance test on my trigger tells me it bad where the test on the stator says its good. Saves you a lot of money. Also, when replacing the stator or trigger you should verify that the timing is still correct, and adjust if necessary.

Great video, content and explanation. I have the same engine and had the same issue. Following the link, you posted, I purchased a trigger and problem solved!! Thanks for taking the time to assist your fellow boaters.

I've got a very similar issue. Thanks for taking the time to share and post this video and your experience. I've got a two cylinder engine that's not firing on one cylinder. Mechanic says it'll be $800 in parts alone bc need to replace whole ignition system. I'll probably do some training on ignition systems then order CDI box, stator and trigger and replace it myself. Thanks again!

Similar here on a 1994 mercury 135. I diagnosed with DV adapter and multimeter that there was no spark firing on a specific cylinder on each bank. Due to service manual measurement sequence it suggested bad switch boxes. Replaced both boxes and the old girl fired up and ram amazing at idle, but still super rough and no power above 3000 rpm. I did gain about 1000 rpm and 10 mph though from changing the boxes, so I think I’m at least running a v6 now instead of a v4-and-some. I just ordered the trigger and a timing light though to see if the trigger is part of the problem. My engine sounds exactly like your recording running rough, missing a spark occasionally. So I’m hopeful the trigger is the solution!

@FKCamVlogs Год назад

Good news that she fired right up. Share how it went with trigger

@williamrgrant Год назад

@@FKCamVlogs Unfortunately, no change with trigger. So I replaced stator. Runs amazingly strong at idle. Even idles about 500 rpm higher than before. But still no power above 3000 rpm. Now I'm going to rebuild carbs to see if there is a high speed jet blockage.

So I watched your video I have a 2004 pro line walk around with a 200 saltwater mercury and my boat started having problems like the video you have I couldn’t clean out and it was running rough super rough after I rebuilt carburetors I went through the fuel system, put all new hoses and fuel filters fuel pump new spark plugs still nothing so I decided to buy a new stater and trigger CDI ignition call packs everything on the electronics. I’m waiting for the parts. I’m hoping that solved my problem.

@FKCamVlogs 6 месяцев назад

John if upon running you are getting proper voltage, then before anything, I would suggest replacing trigger. Good luck and share your results.

@Coltontraxxas129 4 года назад

Have the same issue. Motor twitches just like your when idling but doesn’t always do it. Also when I put the boat in the water the motor seems to. It have the power to push the boat but when it’s out of the water is will rev all the way up. Also around that 2500 rpm range it would want to stall and have zero power.

@FKCamVlogs 4 года назад

Is it the same kind of motor? My issue was the trigger. I have separate video on trigger replacement. Its a cheaper replacement than the stator.

@Coltontraxxas129 4 года назад

It’s a 1987 Mercury 60 hp. It will twitch sometimes and stalls and revs up perfect when it’s in neutral and in gear out of the water but when put in gear in the water it want push the boat past about 2500 rpm it wants to stall out. And if it makes it past the stall point full speed is only 17mph. Sounds like the trigger isn’t working properly.

I've had a 98 and a 2003. They both leak when trimmed up. My fix was to cover it with a rubber gasket with a metal clamp on it. Can't replace oil as easy (need to remove cowling) but at least it stops. Bad design. You can also keep it half full... but that's a bad trade off.

Hello Sir, I saw your video about your engine running rough, caused from faulty trigger. Thank you for sharing it. I picked up a Bayliner trophy 2002 mercury 90 hp 3 cyls 2 stroke 5 months ago. About 2 weeks ago I took the boat out and started to running rough. I did compression test. Cyl 1 =155 psi, Cyl 2 =160 psi and Cyl 3 = 160 psi. Checked found spark on all 3 cylinders. I changed plugs, new fuel, rebuild fuel pump, rebuilded carbs to spec, replaced fuel line and secured line connection make sure no fuel leak. The Engine still running rough. Seem to miss fire at idle like your. Engine running rough but still available to get the RPM up to 4000 and I can still feel like miss fire. Checked firing order and timing with timing light. Everything seem to be fine. Just don't know why keep running rough. 😕. I went head and ordered a trigger. Let see after install.

@FKCamVlogs 3 года назад

@danlong9757 3 года назад

@@FKCamVlogs Hello Sir, After installed the trigger the boat idle great. But when on load, still felt like miss fire/ back fire. I did notice lot of smoke came out the exhaust. I am Thinking could the oil injection pump failure and allow lot of oil to mixed with fuel.

@FKCamVlogs 3 года назад

I would open one or two spark plugs and check the condition on oil. Also make sure you have plastic carb cover installed correctly. Some people install it upside down and that causes issues too

@danlong9757 3 года назад

@@FKCamVlogs right now I have the carbs cover removed. While checking wiring. I found 2 out of 4 stator wires burn and voltage regulator wires burn and melted together. This may cause shorted to ground or power. Will check some more.

So I was fishing a tournament and we got the motor started finr and everything it was running amazing like it always does then we stop stsrt it up again and the noise changes something made a loud noise and now it won't go over 5mph without shutting off so we had to slowly go back at 5mph It sucked. We had to leave. Our mechanic said our lower unit was going out soon and that their were metal shavings in the oil. So it might of been that. We have to take it to him now to see what it is. (Later we took it to our local lake to test it again and it sounds worse. It's shaking bad and making a loud noise not sure where it is coming from tho)
