ID:	284716Been reading and seeing some very good custom intake work for the 300x...all to give more air to the engine bay for better accel and maybe a little more top speed...I've worked on one I like to share that didn't involve too much drilling, low cost and very little chance of any water intrusion and above all brings in alots of air under front hood....

    Here was a list of tools and materials:
    1)2 thru hull fittings 3/4" I.D.
    2)4 ft ribbed hose 3/4" I.D.
    3) 15/16" spade bit
    4)dremel tool with plastic cutting wheel
    5)silicone clear
    6)polyurethane tube
    7)zip ties (4)
    zip tie bases (4)
    9)box cutter
    and a few more minor idems

    isnt it small for an air intake though?

    the larger the tubing and mouth the less chance of reverse or sucking pressure bringing water right back in
    see how you go but im with nicjak

    Sorry but cant see how that can happen ....first that nose of the Ultra is rarely submerged especially with the pump wedge now on...two the hoses run up so any water would drain back...three any water is pressurized thru is gonna end up in the storage bucket or just roll down the sides...

    After riding close to 60 miles in 1-2 foot chop but certainly not rough surf the hull and the storage bucket was bone dry....best I could achieve was 75.4mph on a full tank like before....but the accelerate felt little more crisped I think

    You need volume more then you need velocity. It will help and will help circulate air in the hull witch is always good.

    I will say that is certainly "unique".

    Hope it proves to be an improvement for you.

    Maybe you should consider painting those "Thru-Hull" Fittings red
