Id recomend you dont touch it and take it to a mechanic!! Unless you have an idea what your doing.
But, It sounds like your not letting it warm up enough or not using the right amount of choke.. It will take a minute for the fuel to get into the engine and begin the combustion process.. If its starting and running fine after the second go i dont think you have anything to worry about.. Possibly even left over residue from oil left in the carby and on plugs (the fuel evaporates and leave oil) and it need to burn this off to form a good ignition.
As for the water pump, there is a tell tale (the little water squirty thingy) when this starts to loose pressure your water pump is getting bad.. Fix it right away..

Change the spark plugs, check the fuel filter & clean it of any debris(should be a gauze filter on your engine where the fuel line feeds into the carby's) and see how it goes-first thing that can cure misfiring or stalling cause if the plugs aren't warm they wont spark like they do when hot unless they're real dirty then expect coughing and farting, just remove them and check the end that goes in the engine, if its not looking too clean prolly time for a change!....Carby's possibly needing a little fiddle but start with the basics....BTW manual will be a useful as a bloke in a lesbian colony!
just ask Daniel, some here will have more constructive ideas and suggestions than others!:headbang:

I hope you run your engine dry when fluching after every time out, Yamaha does recommend this to avoid the oil in carby's/on plugs prob!

thanks jason mate ... yes i run my engine dry after every trip and i alway put 5 litres of fresh fuel in before i go out on the next trip ... yea i think i will do i check up on what you said after next weekend if i go fishing because then after that where heading north for 2 weeks and will not be getting used .. then i might try and get some cash together and get it service !!!!!!!!!!!!!!!

I highly doubt an engine that new would need any carby adjustments.. But im sure your experianced to comment on this...
Daniel has since changed his initial question just to deal with the water pump query anyway, and I doubt anything is wrong with the engine stalling after the first start other than the he was putting it into forward before the engine had the required fuel and temperature to operate.
But, i guess you could play with the air/fuel mixtures on the carby, adjust the float and put new spark plugs in it for no reason!

yea thanks guys i sorta found out what was wrong i left the fuel vent shut.... does anyone know where i can get my motor services from cheap because i am saving for this car topper and like some places are like 300 bucks and i can not afford that quite yet .... ah might get me dad into getting it serviced and i paid him later !!!! or thats what say lol

Yeah I feel I am experienced enough to comment after working in and around Yamaha and other outboards for 3yrs at a Yamaha Boat yard-twas only small so often helped the mechanics when an extra pair of hands was needed....Primarily fitted out the boats sold and did have to explain quite often to customers what had been done to their engines in for repair or service. So yes reguardless of what some might think have enough experience to offer a bit of help and it has been help that has been useful to others in the past!:coool:

So you picked up ways to charge people for things they dont really need from them.. Good to see your carring on the tradition....
And Looks like it was all a simple fix anyway!! Much cheaper than some peoples advice!
Sometimes a small amount of knowledge is a dangerous thing hey!
Mr Potato Head
08-04-08, 06:17 AM
Sorry, Daniel, But im glad you sorted it out.. Have done that myself before!
As for servicing, Im not sure if your dad is mechanically minded at all but if he is its not that hard to do yourself, but id recomend not pulling it apart without someone experianced to show you the first time. Otherwise take it to a shop.
I will give a friend a call who live around the shire and see what he charges for you..
Needless to say that leaving your vent shut will not have any effect on your water pump but that's what happens when you edit posts.
If I remember your original post correctly you had startup problems and your fuel vent being closed won't effect this either.

what is a feul vent ?
Mr Potato Head
08-04-08, 07:26 AM
Well actually FED......
If your fuel isnt getting into your motor and its stalls, thus not turning the water pump... and you get the picture!
At least with it closed he reduced the chances of "That C Word"
It's a small vent to allow air into the top of your fuel tank Maurice, allowing air in to replace the volume of fuel used. If it's shut or blocked a motor will starve for fuel once a vacume starts forming in the tank.
The 'C' word? HaHaHaHa!
I wish Haji was here I'd like to ask him and Dogcatcher if they've collected any 'C' yet.

Its a breather.. On plastic tanks its usually a small screw in the fuel cap.

I doubt very much that you have the capacity to sit down & do a diagnostics in regards to why a motor is not performing correctly.
Working in a boat yard as a goffer for the mechanics does not make you a wizz on motors in order to do that you need to comprehend how a motor works & I've read alot of your reply's to peeps & all they are is a general yap yap with no direct information given.
Doubt very much you've ever changed a water pump nor done more than change spark plugs on an outboard so I wouldn't be sitting there Big Noting myself if I were you
As for the water pump, there is a tell tale (the little water squirty thingy) when this starts to loose pressure your water pump is getting bad.. Fix it right away..
Not the case @ all I'm afraid Spud
If there's a blockage & most likely place would be around the thermostat housing then only a trickle of water will come out of that hose.
That dosen't mean the water pump impellor is worn or faulty or the powerhead is not being cooled correctly all it means is that the water is being extruded via another water outlet down near your exhaust ports
Mr Potato Head
08-04-08, 08:41 AM
Your right Jumpus...
BUT Because in the answer to his question...... When there is little or nothing coming out of the tell tale, Its telling him that something is wrong, And its either a blockage or the waterpump.. Its the only indication your going to get other than pulling it down...
So To;

I still say, there is a tell tale (the little water squirty thingy) when this starts to loose pressure your water pump is getting bad.. But also check for blockages! Otherwise, Replace it as per the specs in your Manual.

I wouldn't be HaHaHaHa'ing to loudly Fed if I were you DC has the capacity to work out & understand how C gets caused & how to combat it.
And DC dosen't fill his tanks up with double doses of 2 stroke oil only to call in his mechanic to work out why he needed to call in Sea Tow to get him back to the ramp does he ??????????????????????????
To all you guys who tighten up your breathers so as they are shut !
That is the stupidest thing you can do , they are there for a reason & that's to let your tanks breathe.
So what if you lose a bit of fuel , that's better than risking the chance of splitting your tanks & if your not going to use your boat for a while ? then dont leave the tank/'s full

Yep Yep Daniel has this bad habit of editing his posts & I do sort of recall his initial Q's & I think he asked why his motor wasn't idling correctly when he 1st starts it up.
With the later model yams they did away with the electronic choke system & don't have a manual one either unless you remove your cowl.
I have the same prob on my wittle 50 hp 2 stroke Yammy & sometimes have to restart it a couple of times B4 it starts idling smoothly only when the motor is dead cold.
Water pump pressure works off your driveshaft so if only a trickle of water is coming out there's no need for alarm bells, once the motor warms up then that trickle increases to a more pressurised jet, this can also be achieved by increasing the revs a touch BUT DONT rev out the motor.
Only way you can really check on your water pump impellor is to pull it out & have a good look @ it.
Just had a looky & dug up a reply Idid some time back on how to do this

Fed you really need to wake up to yourself & think B4 you open your mouth.
The only tanks that have closable breathers are the portable carry plastic 20 litre ones.
Now if you used even a wee bit of common sense you wouldn't be making idiotic coments like the one you just did.
With those tanks people can put them in the boot of their car go fill them up without having to tow their boats to the servo.
Closing the breather for a short time when the tank is in the boot stops the fuel from spilling into the boot.
You better write that one down in your diary for future use use to avoid making ridiculous comments again
So it's OJK to close the tank for a short time in the boot but not OK to close it for a long time in the boat?
What if someone forgets and leaves a closed tank in their boot for a long time? HaHaHaHa!

Fed !
For as long as I've known you on the net you've tried proving me wrong & you've yet to succeed in doing that.
DC dosen't enter serious topics unless he can back himself or has knowledge of the topic in Q.
You on the other hand Well it's now time for DCto have some fun as per your request :rolling laughter:
* If someone posts asking why their steering wheel isn't turning your advice would be It'a a Fuel prob
* If someone posts asking why they cant get spark your advice would be It's a fuel prob
* If someone asks why their rollers aren't turning on the trailer your advice would be It's a fuel prob
Do you get my drift yet Fed ??????????????
I also fished aboard your boat many moons ago for a couple of years & that taught me alot, cause one in every 4 or so trips saw us never leaving port due to motor failure.
From that I've allways made sure my boats are in tip top condition well maintained & I never have to abandon a days fishing due to mechanical breakdown & one of the reasons for that is because if a prob ever does arise I can solve it on the spot.
So let me ask you now
Are we having fun yet?:rolling laughter:

Actually I do not even close the fuel vent in the boot of my car anymore because even going down to the shops afterwards for some shopping can make a full tank balloon up with the vent closed.
I just don't fill up my tanks to much leave the vent open and go home straight. I'll live with a bit of fuel smell on my way home.
I do not remember when the last time was I closed these vents.
What is this running dry thing people were talking about, I have yet to do this. Why should I do it?

That balloning effect is what can cause a tank to split
You'll never see a shut off on a tanks breather on a serious tank only on those plastic ones

guys i asked 2 questions ... and 2 had notting to do with each other ... i did not say like the water pump might not be working because of the cutting out when first starting it .... i asked 2 questions
1. how offen should i change my water pump
2. why was it cutting out then first idling
then i found out why becuase it was prolly too cold , not fired up enough or fuel had not got throught + the vent was shut ... so then i edited my post so i could just found abit out my my waterpump ....

hey jack.
when you flush your outboars, unplug the fuel line, let the engine flush till the fuel in the engine runs out. so no fuel left inside of the engine.and that means no oil left in the carbies when the fuel evaporites.
thats for 2 stroke motors though...

You really should wake up to yourself Fed honestly you are soley responsible for turning that into an issue with your jibberish nonsense.
DC is in full control of that condensation prob & if I recall DC also solved your motor prob even B4 he jumped aboard your Seafairy to have a looky.

hey guys i was just wondering how often should i change the waterpump on my 30hp yammy ... a
Danny boy, thats a funny question to ask. How often should you change your undies? When they stop doing their job - same as the impeller.
You use the boat regularly. You flush the motor regularly. You check to see if it is pumping water. What more can one say? Every 10 yrs - same as your undies.
