Have a brand new 6hp Tohatsu. Only used 2-3 times. Ran fine today for a 20 min ride. About 1/2 hr later was going to go back out with my daughter to teach her how to run it. She opened the choke, pull the cord and it started right up. Engine seemed to be catching so I told her to push in the choke. Engine died. Pulled the choke out and tried to re-start. Wouldn't start. I pulled the cord about 15 times and still wouldn't start. Thought maybe I flooded it. Waited about 10 min and tried again. Nothing. About 15 min later tried again. Started up ran for about 20 sec then shut off. Couldn't get started again. It has a 1/2 gallon internal tank which is full of new gas. Any thoughts.
Did you check the oil level and were you getting water flow through the exhaust?
Mike
Check the plugs.
Clean the carb.
Check the kill switch if you have one.
Those are the problems I've had in the past 35 years.
Good luck.
Be sure the air vent is open.
My guess. Not getting gas.
Jim
Air vent was open.
Oil level should be good. Just picked it up from the dealer last month. Water seemed to be coming out a bit everytime I pulled the cord.
Checked the kill switch. Seems to be normal.
Not getting gas, my thought also but not sure why?
Does it have a fuel filter? If so, check it. Don't know outboards, that is classic sympton on a car.
Or bad gas. Water in gas will prevent anything from going through fuel filter
Going to swing by and give it another go tomorrow. If can't get it going will bring back to the dealer to check out. Can pulling the cord too many times flood it?
If as you say you "just picked it up from the dealer last month", I would take it back...
Does your gas cap have a little knob to open that lets air in?
If it's closed engine will run for a minute or two then die. Maybe you forgot to open it. (Been there done that :shock:)
Ethanol intolerance?
Sounds like a fuel supply issue. If it is brand new, still under warranty, take it back to the dealer. If out of warranty check the fuel filter if it has one, drain the carb fuel bowl to ensure no water is in it. You can also pull the supply line off the fuel pump/carb run it into a solo cup or empty water bottle to make sure you are getting adequate fuel flow. Hate to say rebuild the carb, but if you have some debris left over from building the engine blocking something that may be necessary.
Don't forget to let us all know the right answer when you find out. Kinda like a game show ;-)
My two cents: I have the same engine and had a similar issue. It would start with full choke and die when the choke was pushed in. The problem was an air leak past the whimsy wire hose clamps on the fuel lines. One was broken and after replacement the engine fired right up. Yesterday I replaced the original tubing with better and real clamps. Problem solved, I hope. Good luck.
Hi,
Like mentioned by others.
Check the little knob on top of gas cap. It should be crack open to let air in the tank.
Happened to me too to forget to open it. And did the same thing, run for a while and off.
And, when you start the first time of the day, open the choke all the way, and close slowly as it warm up.
If you re-start not to long after, do not open the choke, and try it first. Openning the choke at full might flood it.
If it doe not start on first pull ,open the choke.
Good luck. But if it does not work well, lucky you it is still on waranty. :clap
Talked to the dealer yesterday. Said I must have bad gas and probably clogged the carburator that's why he showed me how to run the engine dry when I'm done using it. Told him the 4 times I used it I ran the engine dry every time before leaving the boat. Didn't have a response other than to bring it in so he could look at it.
Ran down to the boat this morning. Opened the choke, engine started on the first pull. Let it run a minute then pushed in the choke. Ran it 5 minutes then cut the fuel and ran it dry. Waited 5 minutes, pulled the cord and started right up again.
I think I might have flooded it last time. Had used it about 30 min earlier then had my daughter open the choke and try to start it. She wasn't pulling hard enough and pulled it 5-6 times before it started for a bit. Might have flooded it.
Can you flood it if the choke is closed but you pull the cord multiple times?
If it is flooded, other than waiting a while, is there a way to drain it.
Going to play around with it more this weekend.
Hi,
What you could try next time it happen.
Feel it is flooded, close the gas valve and try to start it, it should help get the gas out. When it look like it want to start re-open the valve.
MIght do the job.
If the carb has an "idle jet", remove it and clean out the tiny passage with a strand of kinked wire, carb cleaner and compressed air to blow out any impediments you loosened with the wire. Hold the jet up to a light befor and after to see if the passage got any bigger after cleaning. Common problem with small motors with tiny idle jets passages.
I also got a new 6HP Tohatsu about a month ago. I've experienced the same problem and did find a solution that work very good (at least ) for me.
When u start the engine cold..pull the choque all the way and pull. It may take a minute or two to warm it up so this is the crucial time...play with the choke until it's warmed up.
If it dies on you...push the choque in an give it full trottle....and pull again...if it's flooded (or not) the fact that u have full trottle will dissipate the gas.
Here I'm assuming that you have an outside thank (if using the build in tank, that another story), vent open and fairly new gas. If old dump it in you car.
Also, even if the manufacturer does say that it's ok to use regular gas...but they also say that that a higher octane gas is also ok..use super.
If you have to clean the jet...I've found that they do sell for welders a tool for cleaning the jets of the torches....it has a variety of rigid wires that will fit your jet.
Finally, I run dry my card only when I know that I won't be using it for a few days or more.
Good luck
