Great video....I have a 1998 Sea Ark 16MVT with a 50hp Etec with tiller tilt/trim and a 4" Atlas Micro jack plate. When the jack plate is call the way up and the boat is trimmed 3.8 seconds the prop is in line with the tunnel. It is a river man's dream boat. I can get to places only people with similar boats su h as MVT, MvJT and surface outboard (mud motors) can get to. I do not have pods on the back not what you have on the back of yours. I bought mine this past May (2023).
Another way to vent or add air to the tunnel is to put a couple of 1/2 inch tubes in the tunnel that run from just proud of the transom to near the forward edge of the tunnel. If the forward edge detail creates a low pressure zone the air is drawn up the tubes from the transom end. The advantage of is system is that there are no hull penetrations
How did you know how big to make your tunnel? Thinking of adding a tunnel to my 17 River Ox and want to make sure it's big enough to feed a 60 hp motor.
I loved that setup. I it was well rounded, worked good in deep open water, and could run real shallow if there was a soft bottom. I recently switched to a jet because i started running a lot of shallow rivers with rock bottom. Jet definitely works better for that, but doesn’t work real good on rough water.
