Got an 1872 (18' long 72" bottom width) modified V SeaArk with a 70HP Johnson. It is basically a flat bottom in the back and a v in the front. Very stable boat for bowfishing.
Already got my hands on a Berkley 12JF pump and have a SB Chevy 400 that I am going to rebuild with alum heads. Not planning to get crazy with the hopups for the engine right now. I would be happy if it ran 40 mph but might have a heart attack if we get 50 out of it.
Got a whole ton of work to do but being able to run super shallow and avoid all those underwater stumps will be worth it. Plus go fast is always a good thing. My buddy has already converted his boat and learned what not to do when mounting the jet in the boat.
Think my my speed hopes are realistic? My biggest concern is cavitation while on plane.
