DLM, with a jet, one still needs a way to keep the kicker pointed in the right direction. And a tiller is just out of the question.
I have a jet and have no problem steering with my kicker using the tiller. I rarely steer with the tiller as I use the remote for my bow mounted electric motor.
A big advantage to a jet is that you actually have brake of sorts. I can be going 30+MPH, slam the controller into reverse and be stopped in a boat length or so and at the same time crank the wheel and be heading in the other direction.
A down side to jets is that you need to be going at least 5 MPH or so or you will be turning the wheel a lot to stay on course.On the other hand on my jet, I only have 1/2 turn on the wheel to full lock.
A jet will also have a larger wake when off plane.
All jets, depending upon the type of pump can and will injest debris. Some pumps handle rocks and sticks better than others and some pumps are easier than others to clean out.
The Hamilton(and its clones) handle rocks and sticks better than most, but, the clean out for inside the pump is inside the boat and if you open the clean out on the water the boat will flood. You pretty much have to take the boat out of the water, or back the boat into shallow water. American Turbine (and their clones) have the clean out on the outside of the boat, it still not easy, but you can clean out the pump while on the water.
Hamilton pumps also come stock with very good reverse bucket. I have an American Turbine rock crusher, it actually spits rocks out, it came with a sad reverse bucket. I installed a high thrust reverse bucket that is larger than the Hamilton's and it works great.The high thrust part is a nozzle that is 2" smaller in diameter than the stock nozzle. I have lost 7-10 MPH in top speed, but I can get on plane in about a boat length and be at top speed in less than 2 boat lengths. This comes in real handy when going up rivers such as the Rogue.
Everyone who owns a jet should carry a grate rake, this allows you clean the intake grate while standing in the boat or on the swim platform.
My jet has a fairly flat bottom, so it rides rough in high waves, I chose this bottom because I go up rivers a lot. If you spend a lot time in high waves just a deep V hull, there are many jets with type of hull.
I find that a jet is more versatile than a prop. I can go pretty much where ever a prop boat can go, but a prop boat can's go nearly as many places as a jet.
Driving a jet takes some practice it takes power and speed to maneuver, requiring you to work the throttle. Docking takes more practice than with a prop. You need speed to maintain control, so your dock approach will be faster, but, since you have brakes, you can stop on a dime.You just have to get used to docking at a higher speed and work the throttle more than on a prop boat.
I should also add that a jet eats more fuel, especially when going up fast flowing rivers. On the Rogue I burn 8-12 gallons/hour, on a lake about 5 gallons/hour.
On the other hand, On East Lake (10MPH speed limit), I averaged 8 hours/day fishing and burned 12.5 gallons in 10 days. I only ran the jet 2.5 hours so I could put a little charge to my batteries.
