That is really looking good man. Thats a big deep tunnel. Cant wait to hear how she does on the water.
Console looks great too.

I thought it looked deep. I had a blueprint from outboard jets but now that I'm ready for it I can't find it anywhere. let me know when you make your final decision. My supervisor is suppose to get me a price on a sheet of aluminum to do the tunnel and build a center console

Thats a nice lookin boat. Your'e going to need to change the design of that tunnel though. I'm sure that will be plenty of power with that motor though. It's gonna be fun. Tunnels have to be made very near perfect, other wise there is simply too much cavitation. Wait for some other guys to post their design methods. maybe even run to the local boat dealer to examine tunnels on Woolridges and G3s. Make sure youre looking at a boat with a jet tunnel and not a prop tunnel though. I've seen people put jets on prop tunnel boats and there is way too much cavitation.
