Looking for advice on boat size and h.p. ( 21:57:34 SatMar 16 2013 )

We are looking for a used Jet Sled Boat to use on the Klamath and Rogue Rivers..Hoping to get some advice on what Size and H.P. Boat would be best..also wondering if there is a preference on the 2 stroke v.s. 4 stroke...
We don't want to get a Bigger boat or more H.P. then we need but we don't want to be under powered so we can get our mining equipment in and out of the river...We appreciate any advice given..Thanks..

I have had a lot of experience with jet boats. You need to know that a jet will reduce your available thrust and speed by one third compared to a prop.

Personally I prefer an inboard with jet. They are something you can work on and tune up yourself. An outboard, especially the newer ones, take an outboard mechanic to work on them. you don't need a muscle car engine in any inboard set up. One of my favorites is a four cyl. But a six, or small V-8 will do just fine.

If you go with an outboard jet, I would stick with the two stroke simply because of the higher rpm. The higher rpm works better with an outboard jet. It helps to make up for the jet vs prop. reduction in thrust and speed.

Any boat you look at for the stated purpose should be in the 18 to 20 foot range. High sides are a must for safety. The wider the bottom the more stable it will be.

It needs to be flat bottom for running in shallow water. I have also found that you can do well in shallow water with a semi-V that has no more than a 6 degree slope from center to outside chine. The deeper V's will bottom out fast in shallow water.

If you end up going for an outboard jet, I would not recommend anything less that a fifty horse to power the jet. Remembering the one third loss of horsepower over the prop, your fifty horse will only deliver 32 horse when coupled with a jet unit.

Most important with any jet boat is to learn to "read" the river, it will save you countless miseries. You have not lived until you are high and dry on a gravel bar with a full load.

Hope this is of some help.

I also have a lot of jet boat experience on both rivers. Everything Jim says is spot on.

A lighter boat will allow you access through sections of river where a heavy boat won't go. So there is this balance between big enough and not too big.

Just to give you an idea, my 18.5-foot aluminum boat is powered by a single 135 HP Mercury outboard. No problem to get up on a plane with 3 other guys in the boat, even up through the class 2 and 3 rapids. Light enough to traverse 8 inches of water going slow, or 5 inches of water on a plane.

A lot of people are selling their toys these days, so you can really get a good deal.

Unwise to get a pretty boat (that you don't want to scratch) to support mining on the river. Better to make it into a work boat.

Hints: Keep the boat pointed upstream against the current when making a landing. Back the boat (pointing upstream) down into a set of shallow rapids you are not familiar with to figure out the path you want to take. With the boat pointing upstream, you can always change your mind!

Make sure whatever you buy has a dependable motor and pump. Take it out for a test run. Undependable motors spell disaster on river expeditions.

Start in the easy water and practice. Operating a boat on moving (shallow with obstacles) water is not the same as in a lake or on the ocean. You learn the important lessons pretty fast. Better to not learn them in extreme conditions.

Life vests for everyone in the boat. Much better if people are wearing them!

My mining partner has a high sided, 2 stroke, 90 hp, 17 foot, center console that might be avail. I know he was talking of selling it. Currently in Medford. If this might be something you are interested in I can put you two together.
