Mixing 50:1 for a 200 EFI

[Fidgetcranker]

Would mixing gas/oil cause hole shot to suffer a little in my 1999 200 EFI?
I know the hot weather is part of it, but this happened before it got hot as well.

When I bought the boat, the alarm would not stop going off, even tho oil pump was mixing / working properly.
After shop did too much investigation...$$$, he found out it MIGHT be something that costs like $300 more + labor.
Can't remember what the part was called.

In the meantime, I was on here asking whether I should unhook oil... some said yes because of plastic gear, others said no.
So, after I owed shop more $ than I wanted to pay, I didn't want to add the $300 + labor for a "maybe" and unhooked the oil.
Part of that $ was also cleaning rails and change LU oil, impeller, plugs and more I can't recall.

I only ran motor a couple times before this, so I can't recall to compare performance.
Wondering if hole shot will be better if I hook oil back up and find out why alarm keeps going off.

I think in the EFI, that at idle / slow speeds, the oil pump mixes less than 50:1 until it speeds up.
So when I go to take off, it's doggish for a few secs, THEN decides to kick in and go.
Is that because it's burning oil off the plugs at 50:1, then takes off good after that?
It hauls the mail once on plane.

Sorry if this was too long. Just trying to explain it right. Thanks ahead!

Not sure about the sluggish thing.. maybe you need to de-carb? hot weather certainly plays with all of this..

The oil issue.. the cap to the oil reservoir under the cowling will go bad at some point.. it's a pressure system, so any loss, the alarm will go off. It's a $50 part and 3 wires to unhook. Don't be fooled by looks either with this part, smallest of hole will cause an issue.

I doubt it's related to the oil. Like you said it did not do it before with just you in the boat but when you added a partner & more weight....

[Fidgetcranker]

Thanks guys...It did do it very minimally by myself, but it is way worse with more weight. To me it just doesn't seem quite normal. My buddy who is a Merc tech ran it and thought it was fine. He said that's just how it is with that motor. But I only had 1/3 tank and empty live wells then.
I did get another prop I haven't tried yet. I down pitched from 25p Tempest+, to a 24 Fury. Hopefully will run that Monday.

Just thought it may have something to do with the oil being mixed in tank.

If you want improved hole shot and a little better idle you can put some carbon fiber reeds in.

Is it smoking more than before???... Is it worse if you idle around for long periods of time???... Dan

I premix mine and i don't notice any difference... a little more smoke but still runs good....i would rather have a little more smoke than no smoke.....once that plastic drive gear breaks and the oil alarm goes off it's too late.

My 96 200 EFI is 21 years old, I cant even imagine the hours, never had a issue with it other than the ecm and ethanol full related problems. I've ran it like I bought it.
I run a 24 p trophy and found it to be the best all around prop for the 202.

No, smoke is the same as always
Maybe a little worse when I idle out of a big cove or creek, then take off... Also worse when I have fished a while and motor cools?
Seems like when I start it, it almost wants to stall on idle, then that gets better quickly...
then still bad on take off, like it doesn't have enough power to spin the prop enough to plane out, THEN...
all of a sudden it gets full power, and we are gone!

I've heard a lot about those plastic gears breaking, and then you're in big trouble real quick.
That's why I just had it removed when the repair bill was adding up.

What kind of wot rpm's & speed do you get with that prop, say in water that's 80*?
Tho my hole shot isn't great, at wot I end up at 5750 rpm's & 68 mph with a 1/2 tank and alone.
Once on plain with partner, full gas, 3/4 live well...5350 rpm's & 63 mph at wot.

Thanks to all you guys for your replies. VERY much appreciated.

Check your TPI setting, that'll whack your holeshot in a second.

[Fidgetcranker]

Thank you Pat. I was just trying to look up TPI for outboard motors, and all I could find was stuff on the TPS.
I doubt it, but any chance it's the same thing?

TPS = Throttle Pressure Sensor??
What is TPI please?
Thanks.
