ext boxes on 42 straight bottom
 

Thinking of putting ext boxes with bravo or imco drives on my 1992 42 any one have any experience with this.

No but I have ext boxes and ssm 6s for one.

Lots of work for not much gained....
What are you looking to get out of a set?

looking to upgrade my drives and found a set of used imcos with a set os stelling boxes. trying to find out if it is worth the time to install them.

What kind of power are you running? And what kind of gains are you expecting? Back 4 More went through all that stuff over the last few years, he would know 1st hand what you're gonna achieve. I'd send him a PM.

your energy will be better used in savings, for better hardware and more power, to better use the effects these parts were designed after.
i did this with no gains to write home to mom about. i also did it with #4's and stellings with more power. between the power and the added weight to alter the c.g there was a drastic improvement compared to the bravo process.
