I've never heard of a C-Dory with a jack plate. I'd be interested to hear if anyone uses one. Are there advantages?

There will be some trim changes, as the engine is further aft with the jack plate. Also the dynamics around the transom may slightly change.

I have never thought about one for my C Dory's, but have about the Caracal Cat--so I can vary the engine height and tunnel dynamics to avoid cavitation at various speeds. To go thru shoal water, which do only at slow displacement speeds, we just tilt the motor up--and be sure that the water intake is still submerged.

Thinking the boat will run straighter and more efficiently when
idling through the shallows with the motor at 180 degrees
vs tilted up at less of a degree

Don't know that I'll do it immediately

Have to see just how it does the way it is

So I'll know if I like the jack plate on it or not when I do try it

...but I can see as well, all the surprised faces

when they see a cabin cruiser crossing the flats at low tide

Even if it is at idle speed

Shallow water boats are the norm around here, where they run in 8 to 10" of water (yeah, inches). Some of the boats have jackplates, but it seems they often have a slight tunnel at the back of the hull. These are scooter-type hulls that also have no coaming (think: raft-like); keep 'em light.

Other than commercial boats or sport fishers (that have to stay in the channels to get out to the Gulf), any kind of cabin boat is a rarity here.

Two foot tidal swings are typical, and there are flats that show at low tide that these flat bottom boats blast over mid-tide or higher. Not for me, but I understand why jackplates are desirable... on some designs.

With the motor jacked-up vs tilted when traveling in the shallows
you can run at higher rpms without prop-blasting

...and if you still need to tilt the motor
it doesn't have to be at such a great angle to the water

Motor I originally bought this jack for was a 1984 Johnson 140

I had Bob of Bob's Machine Shop, the mfg of the jack also
install a low water pick-up and nose cone on my lower unit

On a 15 foot Action hull that combo would literally fly across the water

Second sea trial seemed to be good

They replaced two of the three carbs on the Honda 75

So I wrote the check

Picking it up Monday

These boats are the easiest to load of any this size I've ever had

...and that's a big plus for me these days too

Anybody know the make and model of this actuator? Folks out in BC want a pic, they apparently have no idea what goes on these boats.
