will let you guys know how it turns out

I have been experiencing over splash at take off and some prop cavitation. I am in the process of installing an 8 inch plate straight across top of tunnel in hopes of achieving better water pressure to the prop. when my tunnel was designed and welded it was left flush with rear of boat. Ill post...

MOST TUNNELS I HAVE LOOKED AT ONLY EXTEND A FEW INCHES OUT THE BACK. IM THINKING ABOUT COMING OUT ABOUT 5 O 6 INCHES DUE TO THE SIZE OF THE BOAT. THANKS FOR THE INFO

HELLO TO ALL RECENTLY HAD A CUSTOM TUNNEL WELDED ON A 2072 JON BOAT. HOWEVER TUNNEL HAS LEFT FLUSH WITH REAR OF BOAT SEE PICTURES. I HAVE BEEN HAVING SOME OVERSPLASH AT TAKE OFF AND MY PROP CAVITATES FROM TIME TO TIME. IM THINKING OF A FEW MODS TO MY VESSEL AND IM SEEKIG ANY IDEAS FROM...

Update, awesome improvement with 4 blade prop. Running 4 blade rubex solas 15 P, thing jumps right out the water..

update, raised 1 more inch, no more splash, I do think I need a 4 blade prop for better hole shot

i read tha tis should be even with the top of the tunnel. Mine is 1.5 inches above and it is still creating a splash. im gonna try to move in up another inch or so and give it another run see how she does.

Hello, have a aluminum jon boat ( 2072 ) recently installed tunnel. I installed an cmc jackplate and cavitation plate. Aligned cavitation plate to about 1.5 inches above tunnel. Tested it and I get a lot of water overboard while boat gets on plane. Once on plane problems goes away and...

good moring all, well these are a couple of pics of the set up. Took it out this weekend and was able to get into a lot more shallower water while on plane. I had to throttle out though.. was not able to punch out ( might need a 4 blade prop). Throttle felt a little off, might need and...

installation of jack plate was a breeze. Once I adjusted to what I think will work, I drilled a couple holes thru sides of plates to lock in place. will test it out and she how she does.

picked up a broken CMC jackplate (hydraulics were bad) $40 Bucks and used it to raise motor. Now motos sits bout 1 1/2 inches above tunnel. also installed cavitation plate. Will take her out for a spin see how she handles. Am I just about right on height of motor or am I a little over?

measured top of tunnel to cavitation plate and I was way off ( below). Even after raising motor I am still about 1" under tunnel. Definitely gnna need a jackplate. I belive a manual will do for now.

couple more pics

Motor is a 99 115, decals read 130(changed decals when I painted outboard) but it pushes the boat quite nicely.. bout 30 mph last time I clocked her using phone app. Really don't care for speed as long as its reliable. Don't know how she will perform now that It has a tunnel. Perhaps it will...

some work on the rear deck!!
