Jetboat Pros And Cons

Wrench can second this, Cavitation can be a bad thing

Ouch, are you talking about the occasional gulp of air that causes a momentary red line. Or did this happen from something more constant?

This was a 100 yard run at full speed to try and get thru a 4" deep riffle about 6 ft wide. cavitated about 4 separate times. Never do that again.

I think we should all take a second and remember that everyone has as much right to be on the rivers as we do. If it wasn't for the good ole days back in the 70s, many of us would not know what a great experience float trips are and would not even think of floating now as middle aged adults.

And occasionally, my group of compadres like to get quite intoxicated on the river because we are not going to be getting on any highways when we are done floating. We are not hooting and hollering and showing our genitals, but it is part of the reason we float, to get away, put a good buzz on, and we're not hurting anybody, or in danger of getting in trouble with the law. I know technically they could bust us in a canoe for being drunk, but we're not attracting a lot of attention by being obnoxious, just having some brewskis and having some laughs.

So let's lighten up on the guys that like to get drunk on float trips, IT'S OUR RIGHT TOO!

That's the prettiest thing I've seen so far today Need help with it or is it already back in service?

Even though I wouldn't immediately blame that on cavitation (over-rev) I would advise making sure a rev limiter is in the ignition circuitry of all jet pump outboards. Was there detonation afterwards that took out #1 ?

If the crank is gonna break that's the best place for it to snap.

It's fixed now but I like your idea of a rev limiter....have no idea about detonation

Since the bearings have been taken off the crank I assume the block/crankcase lived ?

Yes

thats how we are. We float NFoW in the summer and drink massive amounts of beer and whatnot. About the rowdiest we get is when I stand my drunk butt up in my kayak.

BTW, we need to go floating sometime.

Philosophically, does everybody REALLY have the same right to enjoy the river in their own way? In reality, that usually ends up being true, but...

There are conflicts that cannot really be resolved. When one person's way of using the river directly diminishes the experience for others, while those others have no effect on the one, how is that fair? If I go to a small river with no canoe rentals in order to experience solitude and quiet and commune with nature and the river, and some guy in a jetboat comes buzzing up the river, I'm not bothering him in the least but he sure as heck is bothering me.

If you accept that everybody has the same right to use the rivers, then some are more equal than others, because they can use the river with impunity, while their use of it directly affects the experience of others. But what's the answer?

Really, the only answer is to "ration" the rivers. Either reserve some sections for non-motorized traffic, or use some sort of permit system where the motorized traffic can only use a section of river on certain days. Does anybody think that will ever happen? Does anybody really WANT that to happen? I don't think so. But I like the idea of putting an upstream limit on motorized traffic. Like I said before, my biggest fear is that some technology will come along that will open up even the marginally floatable rivers to some kind of loud and obnoxious motorized traffic (in a way it already has...ATVs, but at least the people of Missouri decided that running them in the rivers wasn't a good idea).

I like the idea of non motorized portions of rivers, but who gets to decide?
