Good question.

That would explain the 1/8 twist I have to the vertical shafts
I had on my #6 drives.

Maybe Scott or Marc. from Geico can shed some light!

I have lots of experience with the PT6, and always thought it would lend itself well to boating. However, no experience (yet!) with high performance boating. The PT6 is available in 500 hp up to a little over 1200 hp. IIRC, they weigh about 300 lbs. The exhaust is indeed part of the power section, the duct starts about (guessing) a foot away from the output shaft.

Canthe output shaft of the PT6 be stoped with the engine still running like the T53? If not, then your into a shifting issue.

Yes, it is a free turbine. At idle, it is putting out about 30 hp or so. But, it can be stopped.

Dont know if ya can see this but this is how we stop the t53.

I am familiar with the brake set-up .

Whose caliper mount is that?

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.:D

Your threads I would say rank as some of my favorite.

Do you think arnesons will be needed/required with turbines?

NOPE THAT BOAT HAD 6S BEFORE WITH THEM. Gerry I will call you in the morning so we can hook up this week for the faring, I am trying to get to mikes too to help him not that he needs it, just to help lower the motor in orhook up something:D. I didn't make it to day wife had me doing a lot of stuff hear. so it looks like a go congrats. art:boat::boat::boat::boat:
