Yamaha 150 HPDI and 2 stroke oil mix

[craigie1]

Hi, new to the forum. I have a couple of yamahas one of which is a 2005 150 HPDI I accidentally put some fuel into the tank which contained 2 stroke oil premix for an old yamaha 75hp i also have. Only ran about 200 yards in it, left it sitting a week, went to start it again and it was very smokey and hard to start, realized what I had done put clean fuel in and took it for a run. Ran fine at high speed, came back to berth but now hard to start and cuts out at idle constantly and sounds rough at idle. Any Ideas please?

Thanks

you may have fouled the oxygen sensor make sure to read owners manule no petrolem on motor like wd40 etc. you may want to contact you dealer have cked fo codes. sounds like o2sensor. was this rigged by your dealer? if so you should have been told to pump out pre mix from fuel tank. look into yamahas ring free

Check the filters. Especially the one after the VST.
