Ranger Bob, (sorry, it was RIGHT there), call Thomas (Bunny boy to us that know him, he likes that, trust me) at JBP. (Jet Boat Performance)). He's prolly done more conversions than anyone on the planet.
While I like the old Panther commercials, and the Panther drive on 21' and over boats for cruising, the sad fact is if you want a runner, Berk and /or AT is the way to go, or some combination of the two on a jet drive.
Converting from one to the other is a major issue. Fiberglass work, etc, let alone the hull integrity issues. Call Tom on this.
Tom's gonna KILL me, my Diverters gonna cost me like 3k now! Lol.
