Re: Will it work without a tunnel?
I was thinking a 50hp jet would be iffy on a 18'. It may work, how much power on tap do you have with the prop drive? If you are on the low end of getting on plane fully loaded, it may not be a good idea.
Thought about just getting a 90hp jet? That seems like it would be about right, its what a guide in AK was running, and that was 4 of us plus him in a big aluminum flatbottom. That was a blast!
