Opinions on Jet Drives

Right then Ribmen and Ribettes,

Investigating propulsion systems and would like to know what you all believe is the best
Value For Money Jet Drives that can be powered in a dual operation set up by independent 250bhp inboards.

Want to know about ALL drives, not just the well known.

Ta.

Why a jet drive?

Well,

I am on a fact finding mission really.
Will be using diesel inboards, so a stern drive or jet system are the only two main items to be used (am happy to be corrected on that).
Jet drives are by far the more expensive method of propulsion but have the benefits of being able to work shallow, give greater manoeuvrability and have no prop directly in the water.

Actually, would like to have it expanded to include the same question for Stern Drives.

What about surface drives, I was going to use a jet drive on my other boat but am looking at surface drives now.
What is the boat going to be used for? Rescue work?

Aye,

The drive system also has implications regarding coding, as you can imagine so, need to think of factoring that in too.

Have spent a number of evenings going over the spec'n and we are looking at category B.

How does it affect coding?

The coding has certain items that refer to some drive systems.

Nothing major, more aimed at prop guards so would be stern and surface(?) drives.

Have you got a link to that?

Inshore Lifeboats don't run prop guards.

Do you want a copy of the code?

At some points its rather vague.

Prop guards are required when working in very shallow water, but I think that is more aimed at Category C & D.

The entire code refers to every single aspect of a rescue boat organisation.

So what do ILB's fall under?
