I hope I'm not opening a can of worms here but it seems a 2007 Yamaha F150 can take regular automotive-grade gas. My 1986 Tournament 19 was looked over two years ago with no problems. It seems I should be able to use regular gas.

So, it's difficult to answer the question with or without ethanol I guess. It depends on your setup and I guess where you live.

I'm not sure what you're asking... are you curious about whether or not you can use on-land pump-gas with ethanol? While e-free is great if you can find it, there's nothing wrong with using e-gas. I would always use something like Startron, though - regardless of e-gas (but especially with e-gas).

There's no difference between marine and auto gas - other than if the company (like Valvetech) adds in some additives.

Thanks, you answered it perfectly well. I will fill up at the local station and get going.

I use chevron from a local gas station and have been since 1988. Omc, Yamaha, Suzuki, Honda. No problems.

Fantastic, thanks.

Now I have to get rid of a snake lodged right above the battery...

I had a 2004 F150 when my Marina switched over from 89 octane E10 to non-ethanol Rec 90. The engine immediately picked up 200 rpm at WOT and I saw a small improvement in fuel economy at mid-range cruise speeds.

I doubt the difference was due to the small difference in octane. Since Yamaha does not use an O2 sensor, the engine depends on a pre-programmed fueling profile that was no doubt designed for non-ethanol fuel. So at any given throttle position, the engine was running leaner with E10 and likely needed a little more throttle to provide equivalent torque at each rpm increment.

Newer engines may be set up for E10. In any case, the only real downside of using road gas E10 is that the fuel is not as stable as straight gasoline. So it's best practice to use a fuel stabilizer all the time.

I also like Chevron/Texaco gasoline. I used it exclusively in a Honda 90 with no other additive than StaBil. That engine is now 23 years old and has never needed a carburetor cleaning.

Doc, I completely concur with your thoughts on the octane - octane does nothing for power with normal-compression engines. However, regular gas DOES have more BTU's (energy) than e10 gas. I'm surprised you saw the gains you did as I didn't think the energy difference is enough to make that noticeable of a gain - but, yes, there should be a gain.

Most marinas have the midgrade 89 octane fuels. I'd prob go with that versus 87 at the auto gas station.

I'm fine with it. It looks like a big garden snake. It doesn't look like a viper, so yes, it can stay. Not sure it'll enjoy the waves and engine vibrations.

Damn engine won't start. It cranks, enough gasoline, oil pressure OK. I bought an extra set of spark plugs to see if it does anything.

Dang, it's frustrating seeing that boat not moving!

Is the kill switch in?

You know, that's a great question I haven't found an answer to. It sounds like there is. I remember looking for it for a very long time and never found anything but a snake wondering what I was doing :)

Is there a spot where you would generally find a kill switch on that configuration?

Thanks Keita for that. I was about to start looking into the fuel pump. I smell gasoline though.

I know I'm really pointing out the obvious, but I've cranked away at my motor before realizing I didn't have the kill switch plugged in.

Thanks. It's slightly different but it's part of the Throttle combo. It has a key and that's how I start the engine normally. I checked everywhere and didn't find it.

I'm going to look again. There might be another killswitch elsewhere.

I will take pictures tomorrow to post here.

There is definitely a kill switch - and it will definitely be near the key, whether it's a stand-alone panel or part of the throttle/shift assembly.

I looked everywhere under and traced the electric harness to the battery but saw nothing... Except that the snake is still there.

Here are some pictures:

I'm stumped. There are no notes as to where it is. I will keep good notes on any modifications I do. Lesson learned.

Maybe I'm missing something, but the kill switch is attached to the red lanyard. It clips into the button on the lower rear portion of the throttle quadrant. It appears to be properly clipped in. When it is pulled the button retracts and grounds the ignition. BTW it is now required to be worn when running on a plane.

Thanks for that, I thought I was going crazy and there might be another less obvious switch installed. The one thing I didn't do is to see if the clip is still conducting ground properly.
