tunnel hull or ultra jack??

[T-TOP]

Anyone have any experience with ultra jack plates? I hear they are as good as tunnels is the mud and you don't lose the performance. Any help appreciated.

Would you say the ultra jack does as well as the tunnel in the marsh?

I have a flat bottom Eric Boat. 10in offset jackplate. I can run in some shallow shallow stuff. I can get up in shallow water. I run good through the grass.
What I'm saying is I have neither an ultra jack nor tunnel. I can go anywhere I need to go. Boat gets it.

Ive heard those Eric boats are nice!

T-Top, it is IMPOSSIBLE to drag ANYTHING underwater attached to a boat without slowing the boat, completely IMPOSSIBLE!
It is IMPOSSIBLE to disturb the water in front of an outboard propeller, be it a tunnel, or dragging a skeg, without slowing boat speed. I don't care what anyone claims.

You are right. But the losses would be hard to measure if not barely noticeable.

A tunnel will cost you 4 mph on any boat, ultra jack is about the same. That is unavoidable. If they ran the same EVERY boat made would have a tunnel, why not if there is no loss????
I'm not saying they don't perform as advertised. A tunnel will go places no boat but a mud motor will go, so will the ultra jack. There is a trade-off, speed. BUT, who cares how fast you go if you can't get on plane in shallow water? I have had a tunnel boat, they are wonderful, they get up in places I would never try without a mud motor or a tunnel.

Nailed it!!!

Remember your tiller will be 12" further back if you go with ultra-jack. IMO get a tunnel hull with Hydraulic jackplate and have best of both worlds. Jack the motor to the sky when u need it, but lower it for speed and cornering.

Thinking of adding a JP to my 1548 flat to run skinny water on Vermilion Corp, but saw this thread mentioning an "ultra jack". Anyone have a website or contact number for the manufacturer?
