tunnel hull or ultra jack??
 

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.

Love my ultrajack turned my boat into a marsh machine. I still miss my old tunnel boat tho. Lol

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

Imo No tunnel performs better

My heavy *** 15/54 marshrunner w tunnel performs pretty good in the marsh... its impressed me in Lac... only complaint is how well it turns

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!!!

4-6" Hydraulic Jackplate
 

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?
