Yamaha 60 hp cold start issues

[dark_star]

I have the same motor Fozzy,
been trying to deal with hard starts for over a year.
sometimes have to crank it 10 times before it fires.
After that it will run like a charm.
I have changed plugs, cleaned filters and used seafoam.
I believe the fuel is not getting to the motor.
Try pumping the bulb with the arrow indicator pointing north until you
actually hear gas moving.
also turn on the key switch 30 seconds prior to cranking the motor.
this worked for me last time.
Good luck

Brilliant, many thanks for that, I have removed the prime start and the plunger and needle are both fully out, I have tested through 12v battery and it does not move even after 5 mins.
I think they are about £170 but will order a new one today��

do they warm up?
Have you checked Ohms of the units to see if they have conductivity?
Service manual should have the specs for extension and maybe ohms

Boscoe99 apologies, you will have guessed I am new to forums and hate all things computer so am stumbling through this as best I can.

The outboard is a 2002 Yamaha F60 AET
The serial no is L 402509

I appreciate all the help

Cheers

You are welcome.

Not trying to be an azz when it comes to asking for the specific model of the motor. Sometimes it does not matter. Some times it does.

If you have not read yet that those electrical units are heaters, that when the motor runs it uses the electrical current produced by the charging system to heat up a wax pellet inside that unit that expands with heat pushing the needle out to close off the extra fuel for cold operation.
they do not move very far, so you need to measure when cold and then again after heating for 3-5 minutes.

but then I am guessing they operate the same as the units on 2 stroke.
maybe Rodbolt or boscoe can confirm this.

Some of the 4 stroke motor enrichment systems are very complex, nothing like the 2 stroke

Pheww, dodged a bullet there, phoned a uk dealer, £230 each and there is 2 of them but I went back to workshop n played about with the primestart from no1 carb
Ohms... The multimeter I have showed 0.3 ohms but after connecting up to power and actually being patient, the rod in the primestart comes out so can I assume that it is working?
The other primestart is in behind 3rd carb but it looks like I would have to remove the carbs to get at it, so for now I am going to assume if 1 is working then the other is.
I am going to spray carb cleaner down the recess for the primestart in case it's gunned up.
Could it be the octane levels in the petrol, we get really crap fuel here and I have a Yamaha in line water separator, but was thinking about an octane booster and adding this to the fuel.

So far so good, but a good take apart and cleaning is probably needed to make sure you get all of the passages cleaned out.

being you have 2 of those units, you would think if one plugged up the other would still function allowing the motor to start or at least fire on some cylinders.

Did this motor sit up for some time allowing the fuel in carbs to evaporate and leave residue maybe

I had all the carbs cleaned and re balanced last year.

The 2nd primestart is right in behind the carbs and would be awkward to get so leaving well alone the now but I will play about with it some more tomorrow.

The closest thing to your engine is this in the states:

Octane booster won't help any varnish, clogging issues. Yamaha's RingFree would: https://www.shopyamaha.com/product/d...?b=Search&d=34

For it to really work, it should be used regularly and if the orifice is clogged bad where the RF can't get thru, hand cleaning / sonic cleaning would be needed.

I also would NOT assume the other is working. If your squirting of carb cleaner doesn't help, IMO, bite the bullet, pull the carb, check the prime start and clean the orifice properly...

I've had good luck with this product re a stabilizer and water separation as well: 3rd video, Demonstration | Fuel Additive | K-100

Typical.....can't get ring free over here, but I can get Seafoam so will give that a try.
I know I will have to probably get into other primestart, but going to try the less awkward route first.

Cheers for the links as well

Right today is a very good day, up off night shift, got an email from the company I bought the sea foam off, they wanted £28.99 to post to me.
Told them to ram it, went out to boat, sprayed a dose off carb cleaner down through the primestart recess, pumped fresh fuel through, turned the key n it fired up first time.....first time
I need to adjust idling.....about 600rpm the now, should I be about 700 - 800 ?
I cannot thank you guys enough, your patience with my crap posts and pointing me to the fix.
I was genuinely going to trade it in this year and was offered £1000, it's only done 220 hours from new so to say I'm happy is an understatement.
So cheers guys from a very happy Scotsman.

As a Scotsmans, are you in or out?

Oh we are doomed, I would have an independant Scotland in the eu.

The Conservatives will treat us like a naughty little schoolboy now because we dare upset there rule....

I really hope I'm wrong for my kids sake but I can't see brexit benefiting anyone but the wealthy.

[99yam40]

we will need to see what happens the next few time it starts cold.

could the carb cleaner in there gave it something to start up on?
maybe

but I do hope you are good to go

and the nice thing about 2 strokes running partialy clogged carbs?????

coins in my pocket .
