Outboard motor won't crank

In this video we look at how to diagnose and outboard motor that won't crank or turn over. Common causes are being in gear, the battery being flat, fuses being blown or bad electrical connections.

I was as excited as Eddy when I got the notification that Stu had posted a video 🤣

Welcome Back

[@RoadhogRNA]

Glad to see you back Stu!!!

[@vindivergilio3482]

Great to see you back (hopefully) and doing well. We all missed you badly!

[@DangarMarine]

Thanks Vin, I've been crazy busy (almost 7 days a week) at work but I'm really trying to make more time for videos. Hopefully things will settle down soon.

[@vindivergilio3482]

@@DangarMarine been same here, with moving from a 11 room house to an apartment complex (a temporary move due to our roof partially collapsing due to weight of snow). At least I still have a garage and a 'new' project: my 2 sons and I are going to convert an aluminum 14.9ft 'V' hull tower into a serious bass fishing rig over the summer. We plan on videoing each step.

@@DangarMarine Hi mate. I have a 2018 Yamaha 50hp 2 stroke with less than 20 hours on it. The motor runs fine when ear muffs attached on land but when the motor is in the water, in FWD and i try to give it throttle it bogs down and won't go any faster than the "in gear" idle speed. New fuel was put in the fuel tank. Can you please give me some advice on what could cause this. Hasn't been used for 2 years, could it be carby issue?

[@mumblbeebee6546]

Good to see you and Eddie again!! (And yes, I am a bit late :)

[@graeme-sailingskeptic]

I feel like Eddie, it's been sooo long... it's good to see you again Stu...

[@Paul-jz1lv]

Welcome back, missed your videos.

[@daved6708]

Mate, we've missed you and Eddy - I'm glad to see again! Keep up the videos.

[@Jacksalar]

I have never been able to understand how electric works but after watching and listening to this video there is hope for me yet, very much appreciate your video's .Jack

[@divingfan9057]

Good to see you back Stu! More outboard diagnosis videos.

[@DangarMarine]

Thanks mate, I do want to do more outboard videos to populate the new diagnosing website.

[@ianc4901]

As an electrician and electronics engineer I found your explanation of a multimeter being the equivalent of squatting over a hand mirror very enlightening ! Next time somebody asks for a detailed explanation of the fault diagnosis process I'll tell them that ! 😆

[@facilis]

😅

[@DangarMarine]

Well, you know, it's a vague analogy. ;)

[@Puddin58]

Welcome back Stu, 3 months late so must have been one hell of a holiday. Hope these long breaks aren't going to become a regular thing though. 👍🙂

[@bymarcatholictinkering]

Wow that’s amazing how happy that Dog was to see you. Always good videos.

[@khallingstad]

Nice to watch another Dangar video. No rush with any next one, whenever you feel like it :D

[@briangriffin4378]

that lovely dog was so excited to see Stu

[@tank7187]

Yes, he’s back!

[@mgarner79]

It's your fault that I own 7 outboards. 4 years ago when I started watching your channel I owned zero outboards. I currently own 7 outboards, most of which didn't run when I bought them. The correlation is undeniable. Thanks for all the great videos!

[@stevedotrsa]

About time you graduate to a boat to put them on then....😂

[@mgarner79]

@@stevedotrsa forgot to mention I now have 3 of those too 🤪

[@swedishpsychopath8795]

THIS is the good old content everyone wants. Bringing older / not working outboards back to life. The steel boat ting is in the lower scale of okay-ness, but fixing and flipping outboard motors is golden. Please do 95% fixing outboards from now on? But what is up with his looks? No shaving and no haircut? What, is he becoming a Troll? Soon he will be living under the Dangar Island bridge.

[@tonysargent1699]

He's back and he's furry! Great to see you back for now Stu. Thanks for the explanation of the starting circuit.

[@MrWilliam.Stewart]

In this negative world, it's good to see a positive post. It's hard to resist a Dangar video. Always amped to watch a current video from Stu.

[@b1644]

Hey it's great to see you back Stu. I love learning about boats and motors here but also seeing bits about life "down under".

[@carltontweedle5724]

Thought you got washed away in the floods, great to see you back. take care see you soooon.

[@TimsWorkshopTJY]

Good to see you again Stu, I just bough a desktop white board and drew up how to wire up a 12v winch with a solenoid and remote receiver. Folks love the simple but detailed view. My ignition switch on my boat sometimes needs the contacts cleaned for the motor to start. Mine is like a car on the dash not on the control. After cleaning contacts I put a little dielectric grease on them.

[@alxelectronics9615]

My reaction to seeing a new video from Stu is the same feeling Eddie felt! Missed that intro music, welcome back!

[@Pappajack44]

Great to see you back Stu! Made my Sunday. Now I have to go out and work on my pontoon which, is why I started watching you in the first place. I think of you every time I watch Doug on the Seeker.

[@DangarMarine]

Good luck with the pontoon!

[@lukestrugnell]

So good to see you and Eddie again!

[@mikemedic450]

Eddie and me had the same reaction. Good to see you back.

[@andrewsmith6406]

Good to see your face again Stu! The one I always ask people as soon I get the call (and you were right there with the neutral start) is the deadmans. Awesome way of simply testing across a switch as well just measuring voltage.

[@jackson12106]

I'm always perplexed why most (all?) motors will still crank with the tether out. It could save so many people so much time troubleshooting if it fully killed the electronics!

[@DangarMarine]

Yes, deadman's switch is a common no start problem, but as Jackons says below, it will still crank which can be misleading.

[@gillesgomez3091]

Good to see you back Stu. That reminds me some day, the kill switch was partly disengaged. It was not visually obvious and it took me some time before I realized why the engine was not starting!

[@GeneralSpades]

good to see your still kicking around stu

[@mickburns5546]

Really well explained. So many people panic about wiring when in reality, if you understand the principle, it’s pretty straightforward 😊

[@DangarMarine]

Thank Mick!

[@danleicester6875]

Eddy genuinely missed you nice to see him

[@thomasnichols7788]

IT'S BACK!!!! Thank goodness! I actually understood and learned something about electrical working. Thank you, I guess. But now I have a headache and need a Scotch. THANK YOU FOR THAT TOO!

[@paulviles5996]

Mate where have you been, always looked forward to your vids.

[@jmeady]

Good to see ya Stuey.....but I missed Eddie and Daisy more. Cheers !

[@roberthargrave573]

Great to see you back, stu regards from Paris France

[@wildwestcoast8095]

It’s been awhile since I learned something thank you stu for sharing.

[@anttiroppola4414]

Good to see you Stu. And the D squad. One thing i do when working on unfused high amp battery lines is disconnect the negative terminal first and reconnect last. Otherwise that rachet the was used to connect the leads might end up channeling 12V into the hull if one is not careful. Not sure how many amps it takes to blow a ratchet.

[@auger7074]

Sadly being landlocked I do not have an outboard, or even a boat, but the learning is good and it’s great to see you again Stu!

[@DangarMarine]

Thanks mate!

Good info. No one ever thinks to check that their battery disconnect/master switch is actually good, acting much like a loose battery terminal would. Good too see ya stu!

[@kristoffscuba5466]

Just had this on my 4.3 mercuiser inboard. Wouldn’t crank at all. Battery was good and I was getting 12.8 volts everywhere. I used one of those lithium jump starter packs, put the negative on the battery negative, and then put the positive on the positive battery terminal… still nothing, then I put the battery pack positive on the input side of the isolator switch, and the boat fired right up. I took the booster pack off and I checked the voltage drop across the short cable from the battery positive to the isolator switch whilst trying to crank the engine and it was massive. New length of cable fixed my issue. Testing for voltage under load was the key to finding the problem. No load, everything looked fine.

[@corynewton1760]

I hope to see more videos. I am working on my boat and have found your videos very helpful. Thank you for the time and effort!

Missed your videos, good to see you back. Had an interesting lesson last week, motor would not pull over, I succeed hydrolock, it is a newer mercury, and neither owner father or I realised that the gear shift and throttle were 1 control on the tiller arm, it had been put in gear and that locked out the pull start, so the pull start was locked until , the motor was shifted into nuteral
