Boat Engine Won't Start Troubleshooting Steps

- How to fix a boat engine that won't start. There are many reasons why a boat engine will not start and I try to provide as many potential problems as possible within this video. When I took my boat out for the first day of the boating season today (Bayliner 185 Bowrider boat with MerCruiser 3.0 TKS 4-cylinder engine), my engine would not crank! I turned the key and heard no noise! This was strange because my accessories (radio, depth finder, etc.) all had power. I explain the solution to my boat engine not starting within this video and identify many other potential causes as well. Please share this video with others and be sure to subscribe to the IrixGuy Adventure Channel ( / irixguy ) and enjoy all of my boating HOW-TO videos! Have a good day! Filmed with Canon XA10 camera.
Thanks for the video. Have a 4.3 Merc that would not start. It was the breaker behind the carb. Saved me a ton of time winterizing.
Did you replace the breaker or just pushed it?
Thanks. I watched your video and then checked the kill switch....major starting problem solved. This goes to show the old adage"always check the simple things first" still very much applies.
I owe you one....
Definitely! The most simple things are often the root cause!
My boat cranked on the initial start. But after a few tries nothing happened, I've checked as much as i could still nothing. Help. John.
@@johnbooker8434 check your battery pana...maybe theres not enough charge in it to crank it....
Uh
I have a Merc 5.0 260HP and it would crank but not start. After 3 weeks of my marina mechanics couldn't figure it out and tried to replace the ECM (brains) it turned out to be a 20A micro fuse on the motor.
Thanks man
I fixed my issue
My main fuse on the motor needed to be reset
I was working on this for hours thanks
Woohoo!!!!!!
Our mercruiser 3.0 failed to start after we installed a new battery. The trim would work but that is all. We accidentally hooked the battery up wrong and when you do that it causes the 90A fuse to blow. I learned this is a common problem when de-winterizing your boat.
Where is the 90 amp fuse located
Thanks for all of your videos, we are first time boat owners and have a 2002 Bayliner Capri-bought it used. I paid over a grand two wks ago to fix a leak and solenoid. yesterday, we were on the lake, fished a bit and it wouldn't start back up. Now I am going to try to look for the fuses, battery is fine and connected. It happened after we had already had it out on the lake for about an hour. Starting to not like being a boat owner...
+JW Pookie Best of luck bud and thank you!
well how about now?
JW Pookie i
Not that it mattters now but I found I had the same thing (but radio didn't work - I hooked that up though so maybe it was done differently than OEM). I checked the 90amp fuse, the relay on top of engine behind throttlebody and the issue ended up being the little red reset button behind the throttle body. On mine, it has a yellow plastic piece that came down (so the button wouldn't stay in). I saw the yellow piece below it just hanging there and it is now running. Wtf. I lost a day (another one after dealing with a boat that sat for 4 years without being run - but in a garage/climate controlled). Hottest day of the year and I was outside swearing as loudly as I could have. I've got a really nice boat for sale if anyone is looking, lol. 60 hours. 2012 crownline 4.3 tks. Great shape (almost new condition). I can't believe what basket case mode this thing went into after cleaning throttle body, replacing filters, oil, pumping grease to the zerg fittings, filling the tank with better gas (it was 1/3 full initially), removing the electric fuel pump (also bought a backup), new cap and rotor. I also got the speed sensor to work again as well as the oil pressure sending unit. Temp gauge went out 5 years ago and so I got that working again. Holy hell. Boats really do take the fun out of life sometimes. Good luck, everyone!
LOL thank you for sharing!
Hi! Any chance you can give me a hand? Our boat won't start....the engine is definitely turning over and sounding but won't turn on...is it the ignition? Maybe dirty gas pumps? Where should I start?
Also Chance to Glogged fuel filter and air coming in fuel line
but would this prevent it from clicking or crankin?
You just saved the day!
Thank you!
I have a 1995 115hp Mercury outboard. Battery is new I connected the positive and negative wires to the battery but boat power comes on but it won't start. Could it be need a new cable wires for the positive and negative?
BBOYCHENGIE yes the battery cable's do go bad if there bad they will get hot
Thanks for the video!! Could the trim sensors cut the power so that the motor does not start?
Don't forget the starter. I had to tap mine with the handle of a screwdriver to get it to turn over. Luckily we were stuck on an nice sandy lake beach for the 2 hours it took to remember this solution.
At the dock today and turn key starter spinning but won’t ignite. It is on neutral kill switch is runnijg. Please help. Outboard mercury 60 horse 4 stroke
thanks man, it was the reset button, saved me some money, thanks again, frank
Where that
Any ine can help me please, im new on the boat world , i have a old 1995 seadoo Sportster 650 jet boat, the problem what I have is everyttime i start up take a little long ti turn on , i change the spark plugs i dont known what else can be , please help
Best of luck! Many mechanics won’t even touch jet boats :(
We have a glastron gts 2016 207 jet boat. We were on the water running a few minutes later it turned off and then does not want to turn back on, no crank or anything the check engine light goes flashing. if I disconnect the battery and leave it about 10 seconds and connect it back the boat turns back on with no problem but will only stay on for another few minutes ( boat has a brand new battery)
It's could be too much Benzin inside the motor, one issue could be solve by taking out the extra Benzin from Outboarder
The boat has been storaged and now the season start and I am ready to go to the water but,
I have problems with the boat it cranks but won't start the engine
I opened the distributor cap and was all rusted I replaced it and still have that problem,
What I did also I remove the spark and was all wet of fuel I believe was because I try to start a few times,
What I didn't check is the fuses maybe one is burned,
Any idea? Please your opinions will help me a lot
I’d take it to a mechanic if it was me.
2000 Glastron, Volvo Penta 5.0. Boat ran perfectly day 1. Day 2 engine started and then just shut off. Engine cranks but no fuel delivery to carburetor. Only 5 hours on new electric low pressure fuel pump. How do I electrically trouble shoot?
What if the the engine turns couple times but then everything shutsdown? like dials go to zero etc...
Low battery?
Yeh that was it

+David Bell Not sure temperature alarm possibly?
dude, I have been tearing what hair I have left trying to figure this out and right after watching this went out and cleaned the other battery ground cable and hooked it up. presto the motor cranked? I only have one battery in and never have had both in. what is odd was with the one ground cable the trim works and I could hear the solenoid click when I turned the key but wouldn't turn the starter. anyway it works now. Thanks
Very cool! #boating
I have a 91 sunbird with a 4 cylinder ford engine. the engine will crank and run as long as I keep the key turned. As soon as I let go of the key to stop the starter from spinning the engine shuts off. Any suggestons would be helpful
Rebuild the carbs
hey Dave trying to start my 17ft Baja 85 Yamaha engine battery is charged I put red to positive black to neg.there's 3 more wires orange with a fuse and 2 black wires . one black wire has a blue tag other has a clear just not sure what wire go were.can you help please..... when I try to start boat no start... thanks anthony
Woohoo! Good eyes :). Gotta love Bermuda!
My key intermittently does not trigger starter. Almost got stranded yesterday. Ignition switch,solenoid, or starter?
+Dave Moorehead If it wasn't intermittent, I'd suggest checking the battery's charge but that doesn't seem to be the case. Not sure :(
If you hear a click when you turn the key to start, more than likely it's the solenoid or the Hendrix gear not engaging the flywheel
I really need some help I have a 4.3 omc cobra i/o it's an 1988 so I have no fuses no safety switch like this gentleman described I can not get my to start with the key I have to jump the starter solenoid every time it has a brand new starter brand new starter solenoid wires are tight please help it also makes no noise it does absolutely nothing with the key
Same thing with my 98 mercrusier..power at the starter but key doesnt do anything..also no gauges or blower works...just the trim works
2012 Mercury Mercruiser 3.0 mpi cranks but wont start no spark at sparkplug ECM tested safety kill switch okay all fuses are okay !! 50 amps main fuse on engine block has been reset fuel pump tested
Battery tender keeps the battery at PAR 12v+ Trim works fine wht could be wrong?????!!!!
I have no idea. Sorry :(
Its Inboard Alpha drive
Great tip and nice place to be stuck :)
I have a 1986 Evinrude 70 hp that just cranks slow, batteries are brand new and full charged. I put the boat in the water and flooded the motor and the motor cranked fast for a few minutes, spitted and sputtered a few times then the next crank was to slow to start the motor, any ideas? Thanks in advance!
Stephen Weber Sorry, no clue. I'm not a mechanic but have had problems starting my boat before that I mentioned here =( Wish that I had a better answer.
+IrixGuy's Adventure Channel steve take the plugs out turn it over with the plugs out mabie it will blow the fuel out of the spark plug cylinders your loaded up with fuel then heat the plugs up then put back in should start
Thanks for the video. I have a Chris craft I/O. Worked fine until yesterday when I starting it. Won’t turn over. Just clicks. Blower doesn’t work either.
Everything else works. Connected the battery to another battery in case it was still somehow a battery issue. No change.
I checked fuses under the helm.
The blower and ignition are next to each other on the dash.
Any ideas? Thanks in advance
Well i have question. Took a boat on the run for the 4th of july, yesterday run boat dry. This morning 5 am went for fishing, all gear on. Got to the ramp. Straps off, am am thinking let me start a boat for sec. Well u guess nothing happen. Parked on side, disconnect boat from truck, jumpers on still nothing ( Find out starter dead) went in west marine got new starter now boat starts but will not keep running. Any idea why is that . Thanks in Advance D
Did you changing Fuel filter/water separator. They last a year or more but when it's done it's done.
Hi
Can you explain where the temperature alarm actually is
Regards
+David Bell Now that is beyond my skill level unfortunately =(
which way should the starter turn
Didn't know about this Red/Yellow Reset button on the 4.3 Merc? Does anyone know anything more about this?
yea if it was pushed in to far it will not crank at all... you have to pull it out
Erik Chilcott
No, thats not about it. One of the most common reasons why boaters cant start their engine is a FLOODED ENGINE. When you prime the engine and or pump the fuel ball too many times this can cause an engine to become flooded and thus not start. One should wait at least 20 min before trying to crank the engine again. And dont prime the engine.
I have a Mercruiser 3.0 and this is my problem:
engine starts norma for the first time (cold starting) but after working for some minutes, i shut it off and when i tried to start it for the second time it will not start.
Fuel system is ok, Igition is ok. when i checked all spark plugs number 2 and 3 are found a littele bit wet.
I was stuck on the water for 4 hours today. Many people drove by. Nobody cared
Unfortunately, they’re usually too drunk to care. I rescued a boater in a lighting storm once that was paddling and their boat with the top of a cooler. I got them back to shore and not even a “thank you!”
I let my brother-in-law use my boat and he ran it fine then cut it off and he tried to cut it back on and the motor will turn but won't fire up? Its getting plenty of power I can't figure out what's going on maybe it's the fuel pump?
Fuel filter/ water separator
Why the engine turn off after a while? It turn on but doesn't keep on
Not sure....water in fuel maybe?
what about gas in your oil , what may cause this?
idle screw
Wait is this in Bermuda? Looks like it from our white roofs
That is indeed Bermuda :). 🇧🇲
Not start boat no spark
Bummer :(
We accidentally left the batteries on for a few weeks and when we went to go on it last week, we realized what we did. The batteries were dead. We charged all of the batteries and it is still not starting. Any ideas?
Take battery to local Oreily, Auto Zone, etc. they should be able to test battery and tell you if you need to buy a new one or not. I did that for a 3 year old battery and turned out I needed a new one. I'd suggest using a solar battery maintainer when not in use to prevent battery from dying. You can find one of those on Yarkodius.com
how do I get my flooded outboard motor unflooded. I'm trying to go to lake today
Turn off the fuel and crank the puppy til your arm aches. Then fuel back on,pull/push and Ur good to go y'all.
my engine is not priming
OH NO =(
