2004 Pilot House with Yam 150hp 2 stroke now will not start

[ThePeterParker]

It spins but will not crank over. Today I got it started and in one minute died and could not get it to re start for the life of me. I am really starting to think I got a lemon from the dealer and nothing I can do. Any suggestions why it would do this? Amps on batteries 12.4 gas has stabil in it I prime the ball pulled the choke and nothing.......It ran ok the last trip and did have 2 times where we had to keep playing with the choke.....just getting frustrated and appreciate any help you can offer.....

It could be a myriad of things. I would start with checking to see if it is getting gas and fire to the plugs. Pull a spark plug and see if it is wet. If it is, hold the plug against the side of the engine block with a pair of insulated handle pliers with the plug wire connected (to ground the plug). Have someone turn the engine over to see if it fires. If you don't see a spark then start simple by checking to make sure the safety stop cord didn't get accidently pulled. I've had this done a few times. Check all wiring connections on the engine if there is no fire.

If the plug is dry and is firing then try changing the inline filters to make sure it hasn't been plugged. Since this is a new to you boat and may have sat around for a while it might have some junk in the tank that has plugged the filters.

These are the first steps I would take before I would head to a mechanic. If you did have some bad gas in the tank it might have worked it's way in to the system and hopefully got caught by the filters.

Good luck and keep us posted on progress. Any boat that sits for a while (how long has it been since this boat was run) has the potential for fuel separation and water buildup in the system. I have a F150 four stroke but there is a fuel water filter with a visible indicator under the cowl. This is an easy visual check to see if the orange ring is floating.

Thanks Steve it was ran in the beginning if the summer so probably sat about 3 months. The dealer also claims they remove the gas and put fresh fuel in. We keep posted as to what I find.

Try this on any 2-stroke that won't start. And definitely on one that has SAT for any length of time. As I bet she isn't primed or choked enough.

1) Put key to ON but not to crank

2) Prime bulb hard, makes sure OB end is higher than the rest of the hose, as that is how the check valve inside was designed to work

3) Yam uses a choke toggle switch, or push IN on the key ... either way, push IN or press toggle switch, HOLD, and slowly count to 6 or 8

4) Release choke/primer system ... check bulb again, ensure it is firm, then turn key to crank

I bet she fires up!

Oh, on most 2-strokes that have sat for a while, on the fuel pump is a manual choke valve, try flipping it to full choke and crank. Make sue your ignition kill hasn't pulled out , as she'll never start otherwise.

The way to clear a flooded motor is to put motor to FULL speed in neutral and crank - she'll clear herself and light up, where you can back off the throttle before high RPMs are hit. But I still bet you're too lean and no fuel to fire within the system.

Hi Dale,

I tried but still nothing....anyway I have the mechanic coming tomorrow to winterize so I am sure he will find out the problem. Thanks for the help

Hi Guys,

I thought I would update on what the actual problem was. Low and behold the primer bulb was no good and was not letting fuel out. My mechanic changed it and Yeah I am so relieved and cant wait for next season and start early this time because of pilot house.

Good news, cheap and easy. Glad to hear that is all it was.
