"Well- if you put a jet on any
"Well- if you put a jet on anything, it cuts the horse power to the boat by 1/3rd. So if your happy with 35 hp performance, it's a blast to go in the shallows and rapids, depending on the boat. And, you can always put the lower back on.
That package is usually sold because of poor performance. The biggest boat we ever put a 55 jet on was a thin hulled jet river boat about 14 foot. And that performen OK. Was a great "starter boat" and we soon sold them into a 17' with a 120 jet on it.
These all ran the "Rogue" river out of Grants Pass. Which isn't noted for its white water."
