Water Jet Drives

[Tinman1711]

Hi,

Does anyone have any experience of installing water jet drives into a hull? I'm looking at putting 2 into a fast electric hull but trying to measure

anything on a boat hull is tricky to say the least. I'm doing what seems logical (that's the scary bit!!).

Thanks in advance.

Best Regards.

If it was me i would try to fit them closer to the middle  i know it will be a pain for the inlet.    Have you tried seeing how low the hull is with everything sitting in the boat.

Thank you for your response.

The boat was originally powered by twin electric motors, driving a 'Z' drive through a gearbox. The gearbox disintegrated so I

thought I'd try this conversion as a dummy run, before I do something similar to a larger boat. I've attached a picture of the boat as it was. It gives an idea of where the waterline might be.

I take your point about mounting the jet drives towards the middle but the stepped hull makes it tricky at best and because the steps

are not horizontal, the jet nozzles would probably not stay below the surface when steering, unless the boat banked enough during the turn. With that in mind, I've decided to 'fix' the nozzles and use a rudder.

I'm a very experienced boat builder, so I'm making this up as I go along.

Thanks again for your response.
