Engine Stalling

[pipe-Island-Chopes]

Hi, I have a 40HP Tohatsu 2 stroke, Let me recount the last time i took the motor on water.<br />i start the motor on neutrol it works fine and i flick it to drive and it stalls,then took about 10 mins to start it pulling the starter chord and opening/closing the choke. i get about 1 k down the river on max speed and then the motor feels like its in neutral, then it shuts down when i lower the speed on the throttle.Then i spent 30 mins trying to start it again. The other thing is that when ever i run the motor on low speed it shuts down. <br /><br />Can any one please tell me what is wrong?

Re: Engine Stalling

Thy carburetor hath become possessed by the corrupting influence of contaminants. <br />IE..dirty carb. Give it a thorough cleaning and all will be well.

Re: Engine Stalling

thanks heaps man. i was scared id have to throw the awsome motor out where abouts is the carb? I understand how it works and that if clogged it can stuff up the motor, is t6his the falt of all my problems? i.e the slow startup, the stalling, and not being able to run it on low rpm? <br />cheers

Re: Engine Stalling

OK, i found where the carb is.. i didnt take any thing off, and i didnt unskrew any thing, i had a look in the venturi and it didnt look dirty, i felt around it and nothing really dirty was there.. just felt oily and mabe a slight bit greasy. are you supposed to look further and open it up or something?

Re: Engine Stalling

Usually its a clogged jet inside that causes the problem. You ned to take it apart and then soak it in carb cleaner for at least 5 hours. You might be better ofF to take the engine in to a local dealer for them to repair it.

You do not indicate where your are, but if you are located where you can get SeaFoam and SeaFoam Deep Creep,go buy a can or 2 and mix with about 3/4-1 gal on gas(premix) in the small tank and run that a few minutes Some times that will clean out minor obstructions. If that doesn't work, cleaniing is the next step. Deep Creep is a spray that you can spray into the venturi of the carb, but fuel mix would get to to inside parts better.

I had the same problem with my 40 hp Nissan (made by Tohatsu). My son cleaned the fuel filter and blew out the fuel pump and it works fine. Also, check your in-tank filter. Just unscrew the elbow to which the fuel line is attached. Good luck.

Re: Engine Stalling

DAMNIT<br />Results back from my motor!.. <br />A compression problem in the engine! <br />It needs new pistons, new rings and one of the cylinder tubes inside needs boaring<br />Not Good news at all as it wasnt the carby <br />To fix it cost roughly $1000.. damnit<br />any feed back? i just need some reply if its happened to any one this bad

Re: Engine Stalling

Happens all the time....but usually its not a Tohatsu. The repair should run you around $700.00, but the shop may be figuring on a waterpump kit and worse casing the powerhead. If the engine is over 5 years old it is probably not worth repairing.

Re: Engine Stalling

Damnit i just paid 2 grand on that boat includeing the motor.. the boat looks pretty bad, but i thought the motor would be fine.. i have used it once and thats when it had the problems.. so if i wreck it ill be pretty much lost 2 grand and not gotten or used any thing, besides valuble time effort and money.<br />it is much older than 5 years its 12.<br />But i am talking australian dollars here by the way.

Re: Engine Stalling

Hey, why isnt it worth fixing? will it just stuff up again or something?<br />or you recon getting a new one is a better option<br />Well concidering i Just bought the Rubber ducky with the motor for 2 grand AU, i was thinking if i got the motor fixed for 1 grand with a total of 3 grand i spent on it, i might be able to get 3 grand back for them all, then buy a new out board? mabe?

Re: Engine Stalling

A thousand AU$ is better than 4000 AU$ for a new one, but you have to keep in mind....what is going to breakdown next. If you look over all the different engine topic forums that are offered on iboats you will see a lot of people are in love with their ten year + old engines. Personally, I think there is something wrong with them. In a beloved car, a gun, etc., I can see why people might like having something from their past around. But, an outboard is a little bit different. When you are out on the water you can NOT afford to gamble that the engine will get you back in. Here, on the West coast of Florida, someone dies at least once per month as a result from having engine problems out on the water. If you are on a small lake, sure run the risk. But weather changes fast and believe me, no matter how many people have been boating around you all day, when your engine won't start....you are always alone...and its getting dark...and your drifting away from land... and a storm is coming...and sharks are circling...and your Mum and Dad are going to kill you for putting yourself at risk. Gee! Boating is all fun! Seriously, you are the only one who can determine if it's worthwhile to fix the old one, but I really would think about it pretty hard.
