I am a new boat owner and seem to have a problem starting my Yamaha 150 VMAX 2-stroke sometimes. I didn't have any problem the first couple of times but now I seem to flood it and then it will not start.
I thought all that I had to do was prime the bulb and then hold the key in as I turn the key. What am I doing wrong?

Push the release button in the center of the control handle and advance the throttle part way while cranking, will normally work. These motors want the bulb pump up pretty firm on first start.

After it has been started for the day I rarely push the key in to start, only if it won't start without it. Mine will easily flood if I use it after motor is warmed up.

Try just turning the key and no choking.

I don't set the choke once it has been warmed up in the morning. I was applying some throttle before I tried to start it. It doesn't seem to like any throttle when it first starts up cold. If I simply hold the key in for about 5 seconds and then start it, she fires right up. Hopefully she will not flood anymore if I just set the choke for 5 seconds and no throttle until she starts.

I choke it while I'm turning the key for about two or three seconds max. Usually starts first or second try every time first thing in the morning when doing that.

I've had the same motor since April, so I haven't encountered many really cold weather starts but what seems to work for me is just holding the key in for a few seconds while starting. Once the engine fires I release holding the key in and just let it idle to warm up. I do not advance the throttle or prime the bulb if I've used the boat within a week or so. If it has been over a week, I will use the primer bulb but only once or twice and no throttle - I do not squeeze the bulb until it is very firm. If I do, I usually flood the motor and it is difficult to start.

I did the typical internet research when I got the boat/motor and many do say it does like to be primed (firm bulb) but this did not work for me. Vary your approach until you establish a procedure that is working for you, but I recommend starting out with as little priming and choke as possible until you find the right balance. I did this in my drive way with the muffs on and quickly got it sorted out without being frustrated at the ramp. The motor runs great and I've been very happy with it.

Thanks to all for your input. The last two trips have been uneventful (thankfully) and the motor has started quickly. I have settled on 4-5 seconds depressing the key in the ON position and then then starting. So far this has work fine. I had considered the muffs option, but Yamaha frowns on doing this I was told so I have stayed away from this as an option. I will try to lessen the time on the choke to a 2-3 seconds this week to see if that works too. I typically have been using the boat every Saturday and Sunday. Once it has been started in the morning, it starts without any issues afterwards. It was just the initial cold start of each day that would have me a bit befuddled at times. Hopefully I am getting more in tune with what this motor likes to get her to running in the AM.
