A lot of the rivers up here have shifting gravel bars that will tear up a prop, and lot of the fishermen have gone to using outboard jet engines. Is there a particular brand or model that is best suited for the extreme temp up here?

Although jet boats do increase you manuverabilty on the river, they are also very damaging to the river ecosytem. The jetwash (the water coming out the engine) comes out at such force it washes away the salmon redds (egg beds) especially in the shallow water where jets are used the most. If you plan to fish on a hatchery stream no problem but if you like chasing wild fish I would recomend staying with a prop or get a pontoon boat that you could float the river with. If we all do our part, maybe our children and their children will also be able to still experience the thrill of a wild salmon or stealhead ont he end of an eught weight bamboo rod.

Speaking of damaging the salmon streams from jet boats (and this may not be the right place to put this) I've heard that a couple of steps in a salmon spawning stream can kill upwards of 20,000 salmon eggs because of the chain reaction from messing up the salmon redds. Maybe somebody knows about this and can explain better but that is somthing to be careful of if you are fly fishing while walking around in your waders. I'll also put this in the flyfishing section to see what response there might be by the informed fisherman.

To Northliner--June 1, 2006
(As posted in Flyfishing Category of Boaters Line Forum)

Regarding the item posted by "North Liner" on the subject of damage being done to nests of incubating salmon eggs; The correct term should be destruction of egg nests, not damage to egg nests.
A study done in Montana (published 1993 edition of Trout Unlimited)on the effects of wading around on trout spawning nests, indicated that just one step on a nest of eggs could immediately cause up to 47% mortality on the eggs. As the eggs that were smashed decay, the spores from the dacaying eggs colonize on the good eggs and kill them as well. This is like having a rotten apple in the barrel where eventually all of the apples in the barrel will also rot.
The item posted by "North Liner" also indicated someone had commented on potential damage that could be done to salmon streams by jet boats. This is an understatement. Both jet and propeller powered boats are capable of and do destroy incubating salmon redds. When a redd is destroyed in such a manner the evidence of a destroyed nest disappears as the trout eat the eggs that are blown from an egg nest by the force generated by jet and propeller driven boats. Additionally, fishermen who drag their anchor at times to slow a drifting boat will destroy any egg nest the anchor is dragged through
Engaging in such activities is like planting a vegetable garden and then walking on and driving tractors all over the planted area. Studies on some rivers in Western Washington have indicated a mortality rate of 97% on eggs and fry.
Until such in-stream activities are regulated during periods of egg incubation, the salmon resource will continue to decline. Hundreds of millions of dollars have been spent on attempts to restore salmon runs. Nothing has been done to regulate such fish destroying activities that continue unabated. It doesn't cost anything to not do things that destroy salmon redds.
