Help! Diesel in boat engine

[gil1]

I have a 15-HP Mercury on the back of a Riverhawk boat. A guy borrowed it and said he wanted to replenish the fuel after. I told him about non-ethanol gas. I later added 2-stroke oil at 45 to 1 ratio.
I went out today. The engine turned over and thick, white smoke came out before shutting down. It didn't start again. I took another look at the fuel, and it looked yellowish/green, even after the oil was added. I can't get in touch with this guy.
If it is frrrreaking diesel, what do I do? I mean after getting new fuel. I'm so pissed! Thanks in advance!

Replace the fuel filter, put some gas in it with fuel injector cleaner and start it up.

Sure he didn't add two stroke oil also???

 

[gil1]

I told him not to, and he wouldn't know how anyway. Thanks.

Might want to drain fuel bowl on carbs also.

2 stroke carb motor?

If so you'll be alright, just drain and flush and roll.

If fuel injected, more of a headache but shouldn't be catastrophic

Well there is no ethanol in it!

Sorry about your luck. I learned long ago not to let anyone borrow my boat and in return, I'll never borrow anyone else's boat.

The one time I did, I let a buddy run a charter in a Ranger flats boat that I had. He came off plane while turning in high winds. A wave caught the bow and he center punched a tripod(channel marker). It separated the cap from the hull and cost me 6 weeks of tarpon season. He paid the $7,500 in repairs and had to sell his truck to have the money.

You can barrow my wife, my house, or my driveway. Don't ever ask to barrow my boat, my truck or my dog.

Wife put diesel in one our first exmark lazer z commercial
Mower. It was smoking and had no power. Called the delaer. He told me just drain it and put high octane gas in it. We did so, it souttered for 3 minutes and was dine after that.

I'd buy some of the high octane ethanol-free pre-mix to put in it after draining and give it a go.

How did this turn out?

Don't know where you are located. But I saw 2 instances of fuel mix ups the past couple days. Could be that it wasn't your friends fault.

Fuel mix-up at Tennessee gas station may have damaged cars

It’s believed regular gas and diesel may have been switched, leading to damage, authorities said.

If you start it with diesel in it it probably wont shut off until all the fuel is gone.

Last week one of our contractors put 30 gal gas in their 26' diesel box truck and drove almost 28 miles before it shut off.
