how bad is it?

went fishing with a buddy over the weekend, we pulled into the gas station and he offers to fill up the boat while I go inside, what I didnt know was he mixed oil with my gas,(motor auto mixes) we get half way accross the lake and the motor starts to run like [censored], what do I need todo? besides not let him fill it up again

what motor do you have? it shouldnt hurt it. usually people double oil their motors after a rebuild. as long as it was the right oil for the motor and not valvoline 5 30 you should be arite. it may have got your carbs dirty tho if its a carbed motor

its a 1985 yamaha 40 hp

I wouldnt think it would have hurt anything, probably just smoke more. It will be alot better than if you ran premix in it and he didnt put oil in it.

For next time NEVER LET ANYONE FILL UP YOUR BOAT.

it should be fine if its concerning you drain it clean the carbs and fill it back up

Invest in some fresh gas, added to the tank and a set of spark plugs. You'll be OK.

Lesson learned, I presume?

yes I did learn my lesson old frog, next time I will just make him pay for the gas
