WaterJet design??

[milcio79]

Hi im making a design of a HSC an d I need 2 engines 320 each, with 2 waterjets, I selected the Ultradynamics UltraJet 305. Now, the question is that my boat has a 23° deadrise, so the waterjets has to be inclined this angle. ¿is there any problem by inclining them?

No problem with the jets as such. Just be careful so that you get the shaft lines correct, i.e. the engines will not stand parallell to the keel when the jet intakes are installed in straight FW-Aft position.

milcio, just in case you become confused, bear in mind that a standard off the shelf 305 has a parallel shaft, this problem will only occur with the 5 degree shaft option, Ultrajet would be unlikely to spec this for your application with a 23 degree deadrise.
