You could install one but if it would increase the speed, I don't really think so. Usually the steering is terrible at low speeds. The only jet drive that I know of for a boat this size is one made by Graupner that Hobby Lobby (Hobby People) sells.

In the real world using a jet pump setup you lose 30% of your speed. In the R/C world I have no clue, just make sure you have a lot of torque. Remember you have to suck and pump the water in and out at the same time.

I have heard before that jet drives aren't as efficient as props. I didn't realized that you'd lose that much speed. I don't doubt that it's true, I'm just trying to figure out why anyone would ever want one. Are there any advantages to using a jet drive instead of a prop other than a shallower draft?

I personally own a 18 and 1/2 foot jet boat. It was made by Challenger in the 70's. I hate it so much. My dad owns a V-drive flat bottom prop drive of corse that is capable of 130mph. My boat is lucky to hit 75. The motor is put through hell, I've been through 13. It's not really worth it to run a jet imo. You don't have to worry about hitting things really or kids kicking the prop or somthing, shallow water is risky no matter what you are in but having a jet drive helps. I just hate it period.

Hi

1/4 scale Stainless steel Hydrojet and the 1/4 scale Jetsprint. Developed and manufactured by Swashdrive Developments. This looks it would do the trick for you.

i have built a 2 foot long thunder tiger powered jet boat using the graupner jet drive the 1st problem is matching the impeller to the power of the engine you cant change impellers like you can props for a start. the jet is tricky to drive as the boat moves on momentum. at slow speeds it is VERY maneuverable especially if you use the reversing bucket. a jet drive with the same engine as a prop is slower but has much more acceleration. the jets also suck in air when wave jumping which means no power till the water sucks in again. but then you only need 1/2!QUOT! of water to run on. the neighbours think your mad when the road floods and you are outside playing with your toys.i have now took out the nitro motor as the impeller is not big enough and it over revs i replaced it with a very hot 540 buggy motor and 6 cells and its much better. more for scale than fast racer if you want speed stick to prop drive.
