Well that was quick. Can you put 100hrs on it quick and let us know how the lower is holding up? Great, thanks.

If the lower does begin to fail again is there any worry about large metal pieces getting into the upper? Did you have the gears of the upper investigated for damage? That'd be one of my biggest worries if I were to go to an SC lower, failure in the lower causing damage or complete failure to the SCX upper.

Ok so now that he is all good and it's cold as hell here in ohio I have a question. I went from standard bravo 1 lower to standard imco sc lowers sense the drives where off and one thing lead to another. Didn' want to change the hight of the drives because finding out thro other people trying it before me and saying my boat didn't like it. So I think it was set up pretty good form the factory. Is the sc lowers way more efficient then the bravo and are they faster in most cases? Or did I just spend 5k to look cool. Lol

Mach1 I purchased this boat with the SC lower already installed. I read on this site a few times that if your boat is traveling at speeds of 75mph and above the SC lowers will be faster (around 5%). So if your boat use to do 80MPH now it should do 84mph. Sounds like money well spent to me. Let us know how she does.

Why change your current setup? Sounds to me that you have a 100 MPH performance boat that is already more versatile than most. Want more low cost versatility?....buy some fishing gear.

Ben,
We stayed with the SC lower and installed a DriveGuardian. I couldn’t be more pleased with the performance of this boat just seems to beat up the SC lower. We’ll see if the DriveGuardian helps. I was responding to Mach 1 installing SCs’ on his Donzi. Fishing isn’t fast enough for me, a lot of waiting around.

I will go ahead and call BS on this, I would argue they are the same if anything. In fact in the basement 80 range, I bet a merc lower would be faster.
