Turbine rigging

[tango]

RIK, how are you ? Just tying to get feedback from the viewers. Must have had a few cocktails before the last post. The old War-Cry hull has turbines coupled to v-drives, thus: rear facing exhaust, built by the same folks that K.R. used. Nice shot of Howards boat in your avatar.

Don't know what you are asking as you as it is difficult to follow your writing, but why would anyone need a V drive?

The engine can plug into the drive. Your asking why are the engines mounted rearward and the exhaust forward. Answer: drive line length. The engine is basically 48" long, the drive line would have to go this length plus. Also the engine would have to be mounted higher upward (when dealing with a Merc #6 that is). Then there is the cooling and such of the V drive which technically is a Parallel offset box. An actual V drive would put the engine at the typical 10 degree angle that is in the V drives.

Did I mention cost?

Whaz up Man?

I like the idea of a straight Arneson....Drop the Turbine as low as possible
and use a Blower Belt to couple it.

Just to many right angles in the #6 drive.

Another idea would be to angle the turbine and run a u jointed drive shaft to
the input of the Arneson.

Rik if ya designed a direct replacement for the six like ya did the
Bravo we would be all set.

The limit in my case is the #6.

RIK, ck.it out, maybe you already have.

just for kicks & giggles -

G, get Rik to send ya a pair off them ol'-drop-box-chain transom mount Arnesons so I can get a hold of the 6's LOL ps: oh ya need reverse rotation in the set up 4-u too.

[Rik]

Gerry, all you'd have to do is plate the transom and install the Arneson

The blower belt is what we did with Gordon Mineo. He actually got several hundred hours on the belt with no problems. Was doing the same thing on a single 32' with Mossmiller before his accident. It is a simple design and fairly cheap.

Oh, you are way behind in the times. The drive is counter rotating, no need for anything crazy.

If I can keep up with ya @ all that would be just fine and thank you ! Was just lookin @ your web site. J - nice pic.& set up in post #66

Another view of a 40' Skater

This is not exactly what I was refering to when I said a slight angle.
No offence to my boy who did this.
The lower the engine the better center of gravity.

One can only imagine how much stress will be on that setup in real water.

Rik where should my prop shaft centerline be in reference to my bottom?

[KnotRight]

On Fuscos 40 the Arnesons look pretty deep.
I think he is sporting t58,s

Probably...not sure if you can stop them to shift, hence the outboard for low speeds? RPM too high, Rik?

[THEJOKER]

You guy's are very sick in the head. That's some crazy hardware!

No, it makes the neighbors happy more than anything. People get tired of hearing the noise from the turbines and there is always someone to complain.

Also, a separate power supply enables one to get back home if there is a problem.

I could put a brake and such on the motor, it's actually better than the T-53 as the brake dust won't go into the intake as its a hot shaft engine, but it isn't really worth it with the marinas and such.

[tango]

So on the Fuscos boat how are the engines and the Arnesons coupled up ? Rik on K.R.'s boat the brake system is inline, but outside and aft. of the air intake. The intake air is not taken from the engine room, but ducted directly to the engines from the atmosphere. Can ya mail order that 40 to me LOL ? www.youtube.com/watch?v=2HpbYDFGrkA

After a closer inspection. Does Fusco have cable indicators on his steering
cylinders. Seems to be a good idea around the docks. But I would think thats
why he has the kicker motor.

[KnotRight]

Notice the rocker plates.

I would imagine if they drop down far enough it would slow
the boat down bigtime.
By the looks of the outside rigging I would love the oportunity to view the rigging
inside. Well thought out to say the least.

steering angle info is probably even more important at 190

Good Point!


The twin rudder deal must corner like ya read about!

[BradH]

Something to think about...because of the geometry of his drives, every time he steers side to side the height of the propeller in the water changes.

Are the little rudders on each drive really necessary?

Are the plates on each sponson movable?
