Default 1995 baja 32 wants to porpoise at WOT

I have a 1995 Baja 32 with twin 502 EFI mercs (415 hp), bravo drives, and 26 pitch Bravo1 4 blade props. When I go for some speed and trim the outdrives up a little bit, the boat wants to porpoise heavily. Is there a fix for this issue, or is it a problem with the hull design. I can fix it with some k-plane, but that cuts speed. I can't get this boat over 71 mph, and it's bouncing at that speed. Help!

Hey there Roadrep I worked at a marina in Harrison Twp. MI. that sold BAJA and worked on many.The 32 had a hook in the bottom to help it get on plane easier.The 24 OUTLAW did as well.Be CAREFULL the 32s also had a tendacey to turn left violently at wot.Have you ever run the boat with 3 blade MIRAGE props? Thats all we used back then on those. Ya know 71MPH is not that bad for that boat,they were made to be a go fast pleasure boat for yuppies.

drive height being raised by a set of 2'' shorties will help the b1 is a better prop if you raise the drives 1 to 2'' and that should stop it. it made a big change in my 24ol ran out of prop at 6000rpm 83.2gps and no bouncing with the shortie. art

Anything I've read about shorties on a Baja is they don't like em unless your running BIG power.

My 32 did great with hydro Q4's at 71 mph also
my friend had 2" shorties on an 01 33 with 500 efi's and picked up about 4-5 mph

Possibly or maybe just not enough HP to push them with the shorties....I'm not really sure, but alot of coin to spend on a experiment. Reason I haven't tried it.

baja raised the drive height on a few of there models including the 36/33/29 back around 02 or 03. art ps thats what hp boatsare about spending money every couple of yrs to go faster I started with a stock 24 ol with 330hp and have spent twice what I paid for it with add ons and motors but over 17yrs its not bad really I could never be happy with a 65mph boat I hope to break a 100 one of these days
