It has one right down the middle with the plug in it at the stern. I don't have a motor just yet. I kinda gave up on the jet being that everyone here in FL thinks I am nutz for wanting one. I have been looking for a nice prop short shaft. But if I find a jet at a good price Im gonna get it. I don't care what they say!
I don't know a lot about them other than I really wanna be able to run shallow, and I just think they're cool.
If you are losing power because of lack of flow of water to the foot due to the keel (I think thats what your saying??) you could try to play with the height of the foot a few mm down or maybe adding a jack plate (if you don't already have one) That would not only give you the ability to adjust up or down but it would also move the foot to the rear a few inches, giving you just that little bit of opportunity for clean water to enter the foot.
Like I said, I am no expert, but just from observation, and a lot of time researching jets I know that getting a good positive flow to the foot is very important. Just like with regular water pump any air or cavitation is going to cause a loss of output or in our case thrust/hp/tourque. The same goes for air to a turbo. You want the cleanest smoothest flow to the intake. Thats why tunnell hulls are so effective with jets. The hull basically acts like a RamAir (or ram water)system for the foot/intake. I would think that adding floatation pods and moving the jet foot back and inch or 2 would have the same effect. Flow of water from under the hull would rise right into the foot between the pods as it travels rearward.
