Will not bolt to the scx-4, this is a scx lower, different bolt pattern than the scx-4.

I’d like to hear speed numbers or prop slip numbers vs the 1400 scx lower as well. You’d think if there was a big increase in speed or decrease in prop slip Jeff would’ve noted it in his post on bookface. Looks to me like bullet nose is more gradual but the rear is the same diameter as a sc or bravo.

We had several things going on at one time with the ole Cig, so hard to make a fair comparison. But I will say that we added another 120 horse to the boat, had it in havasu and beat on it pretty good without a single issue all season. Personally I am sure its faster than the scx lowers with a bravo based prop. The slip numers are in the 13 to 14% But the reasons for my post was more about strength and durability more so than the performance. The Cig is knocking on 110 and still playing with props, so they are running pretty well.

I'd love to hear real world feedback on this drive with a single engine V or small cat setup!

I would like to trade the bulbus SCX lower sitting on the self for one of these, but I would want to test it for a month so I know it's not going to end up on the same shelf.

I need -3 or my gearcase will be in the water causing drag and transom lift.
