A jetboat is a boat propelled by a jet of water ejected from the back of the craft. unlike a powerboat or motorboat that uses an external propeller in the water below or behind the boat, a jetboat draws the water from under the boat through an intake and into a pump-jet inside the boat, before expelling it through a nozzle at the stern .. About berkeley jet drive: berkeley has been manufacturing pumps of many kinds since 1937. the berkeley jet drive was introduced in 1960, and many thousands have been supplied to the boating public since then.. Jet pump angle question. and does it affect the hull's behaviour - i would imagine it might, unless the pump's particular design requires a down angle to achieve the same thrust vector, produced in another pump design with a zero angle. ,the configuration of your boat will make the decision for you.the 251 is a small jet ,so i will.
This jet pump was designed as a modification to a old r/c boat i have. with an impeller diameter of 26mm it is quite large for the scale of the boat. the intake features intake strakes to minimize ingestion of pond weeds and was designed around the input shaft in a brass sleeve with a o/d of 5mm..
