Yea, anything can be fixed, but is it worth it ?
That "Energizer" kit probobly cost as much (or more) than the selling price of the boat. And your still stuck with an insert style pump. Anybody ever seen a loader for an insert style Jacuzzi YJ, with an Energizer kit ??
IMO, if your looking for a boat to just cruise around and not go fast it might be worth looking at. But if you have any thoughts of performance or going fast in the future. Forget about that boat. You will spend lots of money on it just getting it close (and only close) to performing like a boat with a standard Berkeley, Dominator, etc, etc pump.
