Gary, I'm going with the SCX. I'll keep you up to date.
They offer one piece 5" gears and claim gear strength is far better than the merc gear. the prop shaft is 1,7/8" or #6 your choice.Water passages through-out so no need for a shower.
The helmet and drive is (i think) 1" wider. The foot larger and yes some speed could be lost over the Bravo.I was told that in most cases prop and spacer tweeking got back most speed losses.

we'll see what happens....
. ordered the gimble assy yesterday

Tom, I'm very glad you pulled the triger on the SCX, I can't wait to see your results with the new drive. I pretty much have narrowed down to the SCX and the Konrad/ Ace ( thanks Dave at MDG performance, your a wealth of info. Dave is running a Konrad/Ace on his Y2K with great results.) I am leaning towards the Imco with the easy swap out with XR. Best of luck Tom. When do you thinks you will be up and running ????

Ok Gary say you get the SCX what prop shaft do you get ? If you like your props now keep that shaft. I finaly got my slip down to 6% with the number 6 propshaft. I dont know how those props will work with the drive case being so large. Also speedy props are not a dime a dozen.

very good points

Has MDG tried the SCX ? what was the results?

Mike I would think to keep the bravo type props, what are the pros and cons ????

Gary I dont know anybody running #6 type props on bravo type cases. Over the phone they will say anything to sell you sI would stomething. The larger diameter props are a definate plus for lowering the slip number. But low slip doesnt always equate to more speed. Older #6 type props have 14 degrees of rake ,not real good for bowlift. New high rake #6 prop are custom made by throttle up. 5K for a single. Thats one pretty expensive guinee pig. Will it work, who knows. I would stick with what works.

Mike, looks like bravo type props are the way to go.

Here is the first one...

Very nice Rik, can't wait to see some performance data. How much HP/Trq is the drive rated at ? Also no Skeg on the drive ??
