My latest venture was putting a shaker ram air cleaner on my sweet 16. I've put a lot of ram air systems on cars and trucks but this was my first water craft attempt. I've cut holes in $1000 hoods but I was never as nervous as cutting the hole out my Donzi hatch. Unit top is 69/70 428CJ Mach1 Mustang with factory trim ring. Air cleaner is Marine K&N with hand crafted plenum that goes around 1/2 of the air cleaner with a water entrapment system. AT least now I get to hear where my $3.00+ gallon fuel is going!! Other mods include 428CJ factory 735cfm Holley and EMI polished exhaust and Edlebrock intake. the old 350 sounds goooood!!
p.s. found the Donzi Marine emblems on ebay that I have stuck to my exhaust flappers in the hatch pic. Hopefully they stay on!! they are the exact size of the flapper.
