That question can only be answered by Jacques, as I said in my first reply. With a 30HP with a 10" diameter prop it may be possible, but I am not sure.Fuzz wrote: ↑Tue Apr 13, 2021 1:24 am I understand how a tunnel works. What I was asking is will the tunnel on a LM let you raise the motor enough that you hit bottom with something other than the prop. Where I would use one is gravel bottom so hitting with the prop will tear it up. And being as the water is glacier fed it is very murky making depth hard to read.
Good luck with what you learn from Jacques and let us know.
