Hello, I have a 50 HP Yamaha 2-stroke that is hard to start after it has been sitting for just a couple of days. Once it has been started, it will start fine all day and runs fine. I squeeze the primer ball until it is hard and it has plenty of gas. The engine is only a year old.
sounds like your starting procedure is wrong ...... after the bulb is hard you must pull the choke untill it fires up, then you push the choke back and fire it up again ... then you are good to go ...

Hello, I have a 50 HP Yamaha 2-stroke that is hard to start after it has been sitting for just a couple of days. Once it has been started, it will start fine all day and runs fine. I squeeze the primer ball until it is hard and it has plenty of gas. The engine is only a year old.
I also have a 50 hp yamaha that is very hard to start after it has been sitting for a day or two. I was told that my 2003 had a choke that you are suppose to turn the key one click prior to trying to start and that this key position was the choke. I have not had any luck on fiquiring a easy way to start it. I was wondering if you ever fiquired out a way to start it easy.....sure is embarring sitting at the doc and cranking and cranking and finally it spits and sputter and cuts off but when I crank it over a gain it starts up and runs fine for the rest of the day....My problem is I don't have a local yamaha mechanic to take it to have fixed. Looks like I'm probably going to take a 2 hour trip to get mine to the shop. Hope you had better luck in fiquiring out a easy way to get yours started.
You may have the Prime Start feature on your motor.
Try this, works great on my Yamaha 90 that I used to have trouble with:
Prime the bulb very well.
Leave the throttle all the way closed.
Crank the motor for 4-5 seconds - it may start
If not, wait about 5 seconds and crank again, should fire right up.
The key is to leave the throttle closed. Don't bother trying to choke because there isn't one.
Good Luck!

what billi says.
make sure the manual overide is not in the closed position.
if it still wont start correctly the lync and sync may be incorrect or there may be a fault in the prime start system.
but any throttle opening will render the automatic enrichment circuits inoperable.
I have a 2-stroke 25hp Yamaha, same hard starting [15-20 pulls when cold, then started easily for the rest of the day]. Problem was that in the start position, the throttle arm did not engage the linkage on the carbs. Adjusted it so the carb linkage is slightly engaged in start, and the problem was corrected.
