I own an 18 foot Alumaweld Intruder with a Sport Jet and there seems to be excessive pump cavitation whenever in less than smooth water. Has anyone else experienced this? Is it normal?  GWB |

The only thing I can help on this is to check your bottom  . No, No, the bottom of the boat in front of the grate and make sure there are no scratches, scraps or dents that would give less than smooth water flow over the grate. Other than that Sport jet? Whats that? ;D |

The SJ does cav in heavy water. But unless you are running the Deschutes or bigger water ( the Snake comes to mind), unless the water flow to the pump is interrupted, the do that. But just because they do not offer Hamilton performance does not mean they are poorly suited for the job. they work fine.

Fisherman 357,
that's exactly my point. The SJ is a fine powerplant/pump combo. In real heavy water the hamilton pumps are tough to beat. But to appreciate one you need a lot of experience in heavy water to understand the difference.
Kinda like buying a Loomis. A lot of folks do, but how many can actually apply the technology? Maybe 5%. Same with the SJ vs. Hamilton.
Remember ALL pump/hull combos will cavitate under the right circumstances. Some are more prone to it than others.
The only reason I even have an opinion is I have a bud who runs whitewater as a hobby. He goes places most folks would never think of. He understands that torn up boats are an expense of his hobby. After 30 years of playing around, I listen pretty close to what he says. While I may not be capable of doing the things he does with a jet, I am still capable of learning from him. Which is why I posted her pretty much word for word what he says about SJ. Monkey see, monkey do.

How does your bow feel in the water. Heavy, light, or level with the stern. Jet drives are tough to keep full in rough seas. Thats one of the reasons why not many people use them off shore. Does your boat come out of the water often from being light? What horse power does it have versus loaded total weight. A heavy boat with a jet drive will have a lot more bite in the rough. In the flat, she will be a pig.
