Minx 20 with New Imco 2" Shortie
Hi. Saw some of these past posts and wanted to ask if anyone had issues when they put the 2" shortie on your Donzi classic. I am getting major slippage/cavitation since I put the shortie on. I have a small supercharger on a 350 SBC. Should be making around 400hp but still questioning that. I tried a Mirage 21p and a Rev 4 blade 19p and both where very bad. Boat handled real sloppy too. I do have a Rev 23p that I could try but wondering if something else is wrong. Appreciate any info you have on this..
check drive alignment and 1" spacer

A Bravo drive is a little longer than an Alpha and I'm guessing that a Bravo with 2" shorty is similar to an Alpha SS in length.
I would not think 6" below is too high but you could try a 1" spacer.
I would check drive alignment and make sure your steering is tight/not sloppy.
