A properly tuned loader will keep the impeller loaded more consistently. Loader style will depend on HP, hull size/style, intended use, among a host of other things.
Worth? That's your call. A 100 dollar boat and a 200 dollar loader? maybe not.


Jack @ MPD is the Jacuzzi WJ guru. He was racing and setting records in the early 70's.
He would know what works, and might even have one at the shop, IDK.

I have the SE style loader in my WJ.  Unfortunately it's all I've ever run, so I don't have anything to compare it to.
