Just wondering how are you going to control the N2 speed when the boat leaves the water? I am not sure if the standard setup on the T53 works quick enough.
I decided to use the mechanical governor and a frequency counter on the N2 shaft to operate the brake if the N2 went over a set speed, and an over-temp system to aid startup.
A Kevlar blanket is good insurance as a backup!! incase of any failure.

to the freq counter?
Sounds like a good idea.
Thank You!

The engine I used had a pick up on the free power turbine shaft before any reduction took place in the gearbox. You should be able to use the n2 tacho output.

My Turbine builder seemed interested in your idea.
Another thought would be to ride the govenor.
For explanation sake you would lets say have two throttles one would add the fuel and the other would set the govenor
limit.
So you throttle the fuel then you just take the govenor and limit the Rpm via the govenor.
Boat leaves the water it is already on the govenor.
Here is a schmematic of the fuel system taking from the
T53 Work book.
All of the above could be applied mechanical
Via shift cables/Perhaps fabricate a multi stage shift lever
so when applied the throttle would come in and then later
in the mechanical throw the second (Govenor) would
come in and limit the amount of Rpm.
Now that I spewed all that BS Im gonna go watch Mcgiver

Ok this just in.
I made the mistake of telling the turbine builder that
the PSI,s had more bling.
Well enough said.
Whos your daddy now Beotch????
