Extention Boxes on a Baja 36 Outlaw
Cheers XT, thanks for your help so far, if you could pm the price of the front vee cushions and cockpit cover.
Also a bit of advice... i have a pair of 502 mpi gen 6s to go in the baja, they have had a ground up rebuld inc, fully balance, bored out '40 with had everything done the machine shop internally, also new wisco pistons, a wilder cam edlebrook marine heads, fuel regulators and new roller rock gear too. with these engines i was wondering if it maybe worth running with imco extention boxes and bravo with imco 2" shorties which i have from my old boat, any thoughts!? the boat coming over has the standard drives with it too

do one thing at a time,,,get some base numbers after you change something,,,if you put boxes on,,,run it with the drives you have,,,so you can see what is working for you

From my experience and that of Crayola Crazy you will NOT have enough horsepower to make a 2 inch shorter drive work.
I reworked my 500 EFI's to 575 HP and tried 2 inch IMCO shorties and it was a bear to get on plane even with 5 blade 28 pitch P5X Hydromotives and I lost top end. You will need to be in the 750HP and up (more up is better) range before they will help you any.
I have spoke to a lot of guys at Baja about extension boxes on the 36 and for the most part they did not improve performance. However with that said they used them a lot with stock drives back in the late 90's with the lower "X" dimension.
Your best return on your performance dollar is spent on the engines in HP and torque. Then expect to follow up real soon with more $$$ for improved outdrives because the big heavy 36 with sweet HP will EAT your stock XR drives for desert.
Just speaking from experience. Your results may differ. Do not try this at home "I am a professional".
Good Luck
