I'm looking to by my first jet boat specifically a 23' day cruiser with the below deck seating. My preferred choice would be a Sleekcraft. There are a few boats available in my area right now but they all have Jacuzzi Jet Pumps. Should I wait for one to come up with the more desirable Berkeley pump or would a Jacuzzi get the job done? I'm not too concerned with speed i'm just looking for a reliable cruiser. Also what is the cost for a shop to rebuild a Jacuzzi pump if needed?
Most of those were built with Jacuzzi YJ pumps. I have only seen a hand full with Berkleys or Panthers. The YJ is a good pump for that big boat. If you want to upgrade the YJ you can install the Enerjizer kit in it. Most had 455 Olds engines in them, try to steer clear of them find one with a Ford or Chevy in it.
I believe Glastron, Nordic, Carribean, Eliminator, Lavey Craft and Cambell also made 23' footers in that era. All good quality builders in the day. May be more options out there for ya then just Sleekcraft. In my opinion the Glastrons were a cool, unique looking hull that performed very well, very efficient design. (good speed/h.p.) The Jacuzzi pumps are built stout with stainless impellers in stock form. Any of these boats will benefit significantly with a diverter installed. Good luck with the search.
sleeks were always a classic good looking hull aptly named. The Nordic, IIn my opinion, was also a very good looking sleek design. Nordics seem significantly more rare. Good luck to the OP. Patience is a virtue, especially when buying a good used boat.
