Re: outboard jet intake fins
I won't own a jet-drive outboard without intake fins installed.
They are worth their weight in gold as far as I am concerned.
Not only do the fins force feed more water into your intake, it helps to eliminate any cavitation issues caused by hull strakes, lack of cavitation plates, or running in rough water. It does not effect the shallow water performance at all.
You gain power, better hole-shot performance, and high speed rough water control with no cavitation at all; by simply adding the fins.
You can either order them direct from Specialty Mfg, or your local dealer can get them from any motor manufacturer that offers a factory jet drive lower unit. They are all the same; just different sizes. If you had some sheet metal experience you could make a set pretty easy.
The kit comes with stainless replacement pins that are threaded on each end, and use nylock nuts on the ends outside the fin. You need to be sure to use a high grade, marine silicone when you install the fins and want a smooth seam on the bottom with no air pockets. The larger side of the fin goes to the front. Attached is a picture of one I did on a Honda for a guy that sent a boat to Russia.
