I have seen these on many boats originally equipped with jacuzzi pumps. However, I havent heard anything about how much they improve the "seat of the pants" feel of the boat and what kinds of mph increases will be logical over a wore out jacuzzi Y pump? We were going to simply convert the ole boat to a berkley, but the price I have been quoted by a couple guys around here is just about half of what the boat is worth. This thing is just something my dad uses to put around and hang with the local jet boaters, it isnt going to be a drag boat. Just wanting to have a little better hole shot, and the ability to add a place diverter later. Thanks in advance for the info.
