Ignition System Troubleshooting | Outboard Has Spark But Won’t Start | Outboard Ignition System PT 3

[@eyeTHC]

As someone who knows nothing about my boat and engine this 3 part tutorial is crucial for me and others who are confused and stuck on what to do. I learned more from this mini series than I could ever ask someone to explain. What a great tool to know whether or not you can DIY or you’re totally fucked and need to take it in.

John, gotta say. We enjoy your videos greatly. Nobody does it like you

[@tracywatts1459]

4:09 thank you for this tutorial. I look forward to more

[@jamiehall9796]

Thank you for posting this. You saved me thousands of Dollars. My tilt wires were bare. So I rewrapped them. Changed the spark plugs. Checked all the fuses. Replaced the fuel pump from tank to engine. Works like a dream

[@biscuitbassbroom7306]

I know nothing about boats thank you for yr videos ....im learning slowly 👍👍

[@courageous-schools]

A very comprehensive explanation. I am confused about one thing. The heading says “has spark but won’t start.” If it has spark, I don’t need to check fuses or wires. So I have an outboard that has spark but won’t start.

[@davidhernandez8931]

thank you for the great overview . could you give me an idea why the electric fuel pump has power on both terminals? it's a 1998 Nitro with a 150 HP Merc 0D935515

[@michaelrensel9256]

I love how you work on bikes and boats

[@introvertsunited5526]

Love the vids. Could we get one listing symptoms and possible causes? For example I hear a click when I turn the ignition but the starter motor doesn't do anything. New correct fully charged battery. Guage reads about 13V. All electronics to that battery work perfectly. I was told the click I hear is the solenoid so I assume the starter is bad but I only have 35 hours on the motor with regular maintenance done by a licensed tech.

Hey John, I love your videos! They're always very informative!! I was wondering if you could provide me with some advice. I have just replaced the head gaskets on my 2007 F225 Yamaha. The engine is running, however only it's only running on the three cylinders on the port bank. The starboard bank does not appear to be firing. I have checked for spark and fuel, and the injectors all seem to be working ok. Compression on the port bank is 170-175 psi, on the starboard bank it is 150-155 psi. I have checked the spark plugs, and they come out black and slightly wet on the starboard side. The port side is firing ok. I'm at my wits end trying to figure out the problem. I have spoken to several Yamaha mechanics with no success. Nobody seems to be able to tell me what's wrong. Any advice would be greatly appreciated!!

[@trevorspencer6161]

[@grrryetchison9918]

My motor will sometimes fire and other times won’t. Normally will start after a couple of days. Stator test good and also the power pack. Have also replaced wiring harness. 2000 40 hp Mercury. 3cylinder. Any ideas?

[@briancummins6924]

awesome stuff. you should do a 9.9 lower end class.

[@prashantsalian5482]

yamaha f 70 we changed the spark plug oil filter after that we start but low acceleration

[@harryhall7801]

GREAT INFO.I AM WORKING ON MY 2001 YAMAHA 250 HP 2 STROKE

[@MMAGUY13]

Found out my Yamaha 200 the first and second cylinder is not working. Can you tell me the list of parts that control the first and second cylinder I will change them all.

[@johnnybenoit841]

I have a EFI four stroke 30 hp. Mercury. Before I launch my boat I check to make sure my outboard turns over and I'll run it for a few minutes. I have a brand new battery. After I launch my boat I turned the key to start it . But all it would do was make a clicking sound. It seemed like the sound was happening in the frontal part of the outboard. Can you please help me find and solve this problem.

[@johnstrassner8061]

Why would a 2013 mercury 30hp electric start tiller handle have to be cranked for 7-12 full seconds before firing. Not sure what to chase down.

[@legatusaugustipropraetore3484]

Shouldn‘t it be that if the shut off terminal wire and ground shows low ohms when ignition switch is on the switch has gone bad? Should of terminal wire to ground should kill the ignition. Or do I have a false thinking?

[@rogersingley3878]

Great info ! Thanks

[@calitosanto4343]

Awesome video 👏

[@mauriziobezzina3378]

how can i check please the diode cable going to the solenoid and ground , my 60 merc is not cranking ,starter works motor starts only on pull cord , but when turning key nothing happens ,

[@stevedarnell3951]

John I Have a problem, my Mercury nitro series x R 6 1 50. Will not start tries to turn over, but will not. And has a good battery not clicking? But actually trying to start but wont turn over.

[@rudyjohnson6180]

Hey John, My 2017 Yamaha 70 4 stroke will only run at 4000 max. It also runs rough at less than 1000. When I tried to pull one spark plug wire at a time, the engine dies with any wire off. What could cause this. I’ve changed the fuel, filters and injectors. Thank you in advance

[@johnstrassner8061]

Electric start having to be held down 7-12 seconds before it fires 🔥. Any ideas??? 2013 mercury EFI 30hp 4 stroke tiller handle.

[@glenburr2117]

Motor runs as long as you hold ignition switch closed. Starter disconnects after motor starts and runs and throttles up but turns off immediately after I release the switch. Will run as long as I hold the switch closed. Ignition switch???

[@chrisdrentlaw8037]

I have a Johnson 85 horse 1977 outboard engine. It's whistling in the Ignition and on the motor I won't turn over. Please help.

[@jimmybarnett5013]

I got a 50hp outboard and it's not getting fire to the plugs

[@suhardi8037]

Hay saya punya mesin evindrud..... Data Sensor pada mesin saya tidak keluar pada layar monitor , apa yg perlu di lakukan

[@paulgordon9158]

what is the problem when the motor turn over but backfire causing it not to start

[@renesanchez7813]

We’re you able to figure out the problem, because I’m having the same problem with my out bored motor.

[@johnnylawrence]

Got a 1992 9.9 evinrude and i triple checked/rebuilt the carb, replaced the power pack, charge coil, ignition coils, spark plugs, primer bulb, fuel pump, water pump, new fresh gas and STILL wont turn over. I have plenty spark from both plugs. And checked the killswitch and that works fine (obviously since i have spark). And whats weird is even when spraying ether in the carb, or spraying inside the spark plug holes, even putting a little gas in there, it STILL wont fire. Sometimes it sounds like it wants to for a second but then dies. Im at a loss here. Anyone who has any ideas much appreciated.

[@vitaly19]

Did you figure out what’s wrong with your boat engine. I’m having a similar problem. I have spark but it won’t do anything even if I spray gas by bypassing the carburetor

[@johnnylawrence]

@@vitaly19 i havent yet. I put it away for the winter and in the next few months im gonna go back to it. I bought a gasket kit and after i remove the block im gonna replace all the gaskets. I have a feeling when i remove some of the side plates to replace the gaskets im gonna find some badly clogged cavities.

[@brandon61718]

Any updates? I’m having this exact issue with mine and can’t find anything online.

[@allanthomson4639]
