transmission fluid maintenance

This is going to be long!!

I have owned my 89 nautique 1.23:1 transmission for about 2 months now,
it has been running very well...
2 weeks ago I took my boat on a week long vacation. So before my vacation i decided to change my fluids. Oil went okay no issues. Went and bought a moeller fluid extractor to suck out my transmission fluid.

mistake number one, after having sucked out my transmission fluid i did not check to see how much i sucked out.

replaced with new fluid dexron/mercon, put one quart in and checked the level on the dipstick. Rested the dipstick on the first o-ring and it was a little high, just above the second notch. I am like that is okay, when i get to the water i will measure it again. Still a little high, so i sucked some out. Now it is reading to the second notch on the dipstick while cold in the water, i believe it is okay.

Confusion....upon my initial fluid extraction i am pretty sure i took at more than a quart, but when i filled it back up with a quart it seemed high so i removed some fluid until it was on the second notch resting on the o-ring, in the water cold.

Ran the boat all week, sounded fine getting on plane and accelerating, but while hard turning it sounded rough.

At the end of the week, when i put it in gear, it definitely sounded rough.

totally confused i called two correct craft dealers and both said to measure the fluid with the dipstick all the way in to the full level. "okay" i asked, "to the second notch right?", i replied. They both said yes.

That would register even higher on my dipstick????

So last night i again sucked out my tranny fluid, and measured only about 3/4 of a quart????

Put another quart in and while on my trailer, resting on the first o-ring, the fluid level is not only above the second notch on the dipstick but above the machined part as well?

So the question is how much should i put in, where should the fluid be on the dipstick cold/hot, in the water on the trailer???

I am totally confused, when i have done a search here, i am hearing 1.5 quarts of fluid for replacement, and i am no where near putting that much fluid in. Especially if i measure it cold in the water resting on the first o-ring to the second mark??

HELP!!!

Steely capacity is 2 quarts according to manual.
I did a change on mine recently see link below

We also need pictures

Eric,
Thanks for the information.

When i suck the tranny fluid out, how much will be left inside?
Is everyone getting well over a quart out of it?

The transmission goes in and out of gear easily no issues just sounds rough out of the whole sometimes and when turning hard.

What else can i look at to tighten things up back there?

could it be an alignment problem, propeller problem other?

thanks,

Norm

Steely - If you haven't already, check your alignment & strut bushings (for wear). That will cause the vibration.

Sounds like you're OK on the tranny. I checked mine Sunday & it is overfull, hard to tell exactly as the fluid doesn't show up well on the dipstick. I'm going to leave it overfull, as it has been that way all summer.
