Can anyone tell me what these poles are coming out the the top of the Mercury K-Planes?
What are they used for/purpose?
How much are they?

Cavitation tubes coming out of the plates on the speedmasters, not the k-planes. They are used to ventilate the props and help get the boat up on plane.

Do they also create a larger rooster tail?

Nope.
Once the boat is up and running, the 'tubes' are clear of the water. The rooster tail is from the semi surfacing props fitted to high performance drives like these.

RR

For a pair of Confederate Flags. Rated for (with the correct poles) 100mph.

Was that joke politically incorrect ?

And yes, the answer was already given, so that means it is derail time right ?

Fixed it for you.

You beat me to it!
