Get Wet-
Great looking combo! What size props are you running? LOL, I don't think you can go any bigger!

Thanks. 17.25” with 1/2” spacer installed. 17” is max on scx-4 with no spacer, 16.75” for scx

That upgrade package is about half of what I paid for my boat 🤦🏼‍♂️. Looks great though, and I’m sure it’s very reliable.

Check with Mike at CK or Mitch at Custom Marine Service right here in west Michigan , these guys do this stuff all the time.

If the end game is to run SSM props, I’d find out what the prop shaft height is on a 39 700 NXT boat and use that as a starting point, I think the NXTs sit a bit further back, so you might have to go a tick lower than that

That's a good call.

looking at your boat on the trailer in the trailer thread the prop shaft looks to be 4-5 inches below the bottom, unless its just the angle of the pic

after seeing this and going to see the pics, the fact that you have ITS, you will have plenty of water to the props no matter what you do. just have to check with a few people that have them as to how it will get on plane, i know the step hulls tend to run flatter at speed, and kind of have a suction getting going. in theory a -4 should work.

Now that F2 mentioned that I looked at that as well, hard to tell depth but looks like a pretty good size notch in that boat! I haven’t looked at a ton of 39s but I don’t recall seeing that big of a notch in others. That would obviously play a big part in drive height.

I just measured its 4.375 to 4.5 from the bottom of the hull to the center line of the bullet....
