Dont know.
The original owner of my boat had these made.
I have all the rigging exhaust reverse current relays,
SCS crashboxes. Fresh water rinse built into the turbine intakes. Air system to operate the air over hydraulics
which operates the caliper.
I even have the micro switches built into the shifts
which engages the calipers which stops n2 so you can shift the
SCS.
This was one of the deciding factors on going back to
turbines.
What is the biggest expense in rigging a boat with turbines?
The amount of Corona required to figure how all the SH@T
goes together.![Big Grin](/forums/images/smilies/biggrin.gif)

Have you thought about a steering system- 12v electric pump? And how does the air over hydraulic system work?
Brad.
That Corona adds up...

That boat has a direct drive from the turbine; start it and the shaft is turning. Geared down but no transmission, crashbox, etc. Couple boats do this, especially if the output is turning high RPMs, and the shaft can't be braked reasonably.

it has the herring swept backs and all the gears have been replaced. To the tune of $15,000 Gotta love mercury

Will leave the sixes for now. Arnesons will be in my sights.

Now that I have commited to turbines.
I have taken a closer look at the original rigging.
I called the original owner to pick his brain on what some of the stuff was for.
Look at this picture one turbine bell housing has the bracket
the other does not.
He told me it was for a PTO "like alternator".
However the Pto pulley on the inner shaft is missing
That is why it was not obvious.
So I looked through my ever growing pile of Boat Junk
and came up with a pulley after centering and bolting should work fine.

Power steering...........Got ya covered.
This is what they used.
A massive 12 volt dc motor directly mounted to your standard KRC power steering pump.
Dont know if I will go back to this. It weighs more then my
x-wife and draws a massive amount of current.
I,m thinking using the PTO above to drive a alternator
for the 12 volt charge and double up The power steering off that.

Now if I can go off to GEEK ville here for a minute.
This is what I,m thinking.
The tubine requires 24 volt to start the spool
then when it flames You flip a sitch to activate the reverse
current relay which charges the 24 volt batteries.
Instead of running 24 volt and 12 volt batterys whay not arrange contactors to series the 12 volt batterys to go to 24
volt when ignition key goes to start.
Then I am faced with how to charge them with the turbine generator becausease they charge 24.
This is whay I beleave they run two different volt batterys.
The consumption of beer or drugs may shed some light on the above dilema.

Throttling a turbine boat is "similar" to throttling a piston boat "correctly". You use very little throw. Just enough to take the load off.. The key to running a turbine boat is keeping your compressor above 80%. Just like racing a car,cart or bike stay in the powerband. Remember there is no driveline lag to slow your boat down quickly so be prepared to "coast" a little in a turbine cat. Requires some practice and you will spike a bit more than a piston boat. You'll get the hang of it.
Steering. Right now both our turbine boats use a conventional Capalano hydraulic helm.
