yes you are right an oil pump may deliver a very light amount at an idle.
but i know you wouldn't hit the mangroves wide open at anything less than 50:1. premix. thats what i was trying to say.
Is 32:1 too much mix for a Lady Ridden Ported 760?

Hell no.
My motor loves 32:1 and that's what it gets.
I have run 100:1 on a VXR that I had. We wanted to see how quickly it would puke but it kept running just fine.

32:1 will make more power than the 44:1 so i would run that

wheres momar when u need him. he will tell you about rich oil mixtures leaning out your motor.

carbs just need to be re-tuned to correct this problem. Ive also read studies that more oil means more power from reduced friction and other things. You just have to tune properly since you will get less gas and more oil.

That was in an air cooled motor which uses oil to cool it more than we do.
"Only the fixed parts of the engine, such as the block and head, are cooled directly by the main coolant system. Moving parts such as the pistons, and to a lesser extent the crank and rods, must rely on the lubrication oil as a coolant, or to a very limited amount of conduction into the block and thence the main coolant. High performance engines frequently have additional oil, beyond the amount needed for lubrication, sprayed upwards onto the bottom of the piston just for extra cooling. Air-cooled motorcycles often rely heavily on oil-cooling in addition to air-cooling of the cylinder barrels."
More oil means less fuel through the jet per volume of premix. It does lean out your a/f ratio.
To the OP, it's only 4 more ounces of oil per 5 gallons. She will be fine if the motor is jetted correctly.

That's what I want to know. The ski is jetted correctly and quite safely too so a smigion less fuel will be just fine. I was more worried about loading it up and fouling plugs from not running hot enough to burn it off so if the quicksilver burns cleaner that shouldn't be an issue either.
I'll try it for a few tanks and adjust accordingly, thanks guys.

are you implying that the higher power they saw was likely due to added cooling of the engine? i cant see where that causes increased power(not saying your wrong i just need more proof). I was not suggesting we run 15:1 just that a slight increase in oil content when tuned correctly should be fine.
I wonder what data engine builders use to decide what type of ratio to run in their engines?

I don't really know much about it, just stoking the fire to be honest. I just don't believe everything i read that's all.
I think some of there power may have come due to added cooling of an air cooled engine though. Just my opinion there though. may not be fact.
Im going to stop gumming up this thread with off topic crap though lol.

It's all good, I learn as much from off topic chatter as I do from the original topic. :bigok:

I run 32:1, it makes the boat pull harder then 40:1 or above
Also it doesn't make it lean as you just re-jet for it

this ones easy, just get another 32:1 XScream for the lad and toss the 760, she will want the power in a few years from now anywho,, and you know your riding buddy's will as well.

When she blows up the 760 it goes to X-scream for some lovin anyways. :biggrin:

More oil also will decrease the octane rating of the fuel. So as has been said before by others you'll need to fatten up on the jetting.

but gasoline has a better cooling effect than oil. pour some on your hands and you will feel the cooler gasoline.
so by replacing gas with oil you reduce the cooling?
i run 4% in my snowmobile. hauls butt. but it´s intended for 4% i can´t se a reason for 3% taking any harm to your motor. if you start fouling plugs and stuff you can always go back to 2,5%

Now see, I would be insulted if my hubby asked a question like this.
I'm just sayin'. :biggrin:
I would suppose it would somewhat depends on how she rides. My hubby and I do have different compression and run different mixes - his motor needs more octane than mine, but mine is a 760, so . . . . you'll still have to decide. He writes on the tanks w/a Sharpie which mix goes in which ski.
I would try it and see what happens. You can always jump on it and clear it out if you hear it loading up and teach her how to tell when it needs a good WOT run. How do you think I learned about this stuff? I kept asking questions and my hubby has always been able to answer any questions I've asked (he's a pretty smart guy and a great tuner/mechanic).

Too Funny, Lucky for me she doesn't get offended that easily. She's a good rider just not an aggressive yet, which perhaps explains why she doesn't get offended. :biggrin: She's a lover not a fighter. LOL
Your husband mixes different octanes which is understandable, but do you run different oil ratios too?
I'm pretty sure X-scream tells everybody to run 32:1 in any of their motors so what's the difference between their engines versus one built by anyone else? I'm guessing nothing, they just reccomend a cheaper oil and to use a little more of it.
I believe he runs the same oil ratio in all, now. When he does a rebuild, he increases the oil ratio, but not on seasoned motors. I was just telling you about the writing on the cans as our way of keeping it sorted (for the octane issue, now, but it has been for oil ratio issues in the past, depending on who's motor needed the extra oil).

Gotcha. I have tags prelabelled that I tie to my jugs to indicate mixed or unmixed as well.
Clear jugs are nice too for a visual reminder but some oils like the Seadoo mineral oil is honey colored and doesn't change the color enough.
