The whole drive is an interesting concept... almost the same concept as a bmax.

My boat is a 38' Fountain so extended WOT is not uncommon.

As you may have seen in the other thread I started, I am running an SCX upper and SC lower. Ran it for 2 seasons by filling the drive fluid to half way up the bottle. Never had a problem. Are you guys saying that with a complete SCX ( which I will be running next season ) you should only fill the drive to the upper sight plug, leaving the bottle empty? I dont like the sounds of that.

So how do you know if it goes down.. Do you put some lube in the reservoir so you can see it go down if you are losing some? Or do you pull the top vent to check it all the time?
I filled mine up to the vent hole and installed it and then continued till I got a little in the reservoir and then topped off the reserviour to the max line. It has stayed there since then. I only have a few hours on it, and not any WOT.. Just blasts up and down the rpm scale while breaking everything in. Wont know more till the water gets soft again in the spring, more than likely, then I can get out and run it harder, if I can hang on to it.. The boat and I like the new motor!!!

Not sure if the SCX needs this done but when running a BMax you remove the check valve from the helmet... It allows the oil to leave and return to the drive easier.
If the SCX is an expansion tank just like the BMax you can find out easily by opening the hatch and stickin your head inside as soon as you come off plane. The fluid level will be higher than when you started.
The BMax will rise a good 2-3" in the expansion tank and then settle back down after idling for a few minutes. The reason the oil rises is because the gearset is much bigger than a Bravo (5 inches) and needs to expand when it gets airated.

I also have new scx with sc lowers with aprox., 8 hrs on them,behind aprox., 750 hp. My oil level went down a bit and called imco, talked to Dave and he told me just have air in them and will work it's way out.
I added a little oil to both and they are down again.
Changing oil now and wait till spring to try again
All my run's have been high speed trying to dial it in.
I am talking not much oil, but still.
I would like to hook my alarms back up, has anyone done this, haven't looked that far ahead yet, dialing in and boat new to me.
Thanks Joe
