The IMCO SC are still better they the stock bravo's. Just till funds are available for SCX's. The SC are -3 lowers

Where are the current propshafts relative to the bottom?

Not that much better....SC's use merc gears

5 1/2 from the bottom not the notch

You want to lay a long straight edge along the actual running surface of the bottom, directly in front of the drives. Then see how far below the prop shaft centerline is below that with the drive trimmed parralell to the straight edge.

On some boats, especially heavy older fee bottoms, you have to be careful not to go too high with the propshaft height. You may end up losing a substantial amount of cruise speed, and some cases top speed if the boat can't carry the bow.

This is where ext boxes come into play.

Boat looks great BTW. Esp the motors .

Cool! I boat out of Hammond and East Chicago all the time. Look forward to seeing the boat. What dock are you on?

Did that 5" 1/2 to running surface. And about 7" 1/2 to the notch or so

Totally different boat but Mine was 5 1/2 lower and I went from Bmax to full SCX that raised it 3 inches because Bmax had 1 inch spacer. 4 blade prop was terrible w tons of slip but 5 blade Maximus got me the same top speed as my old setup but WAAAAAY better cruise speed.

Am on V DOCK I have the 426 chris craft name (Double Trouble) and the lift V32-V34

Does anybody know where I can pick up a 2.5" or 3" bravo 1 drive spacer? My X dimention is just shy of 3" high (which is why I have so much prop ventalation) and I don't want to spend a fortune on a new spacer so If you have one sitting on your work bench and want to let it go for a fair price... let me know.
