I was really likin the idea until the "have to move the engine forward 5 inches". I'll plead the 5th on this one, since I'm getting started on the Saguaro for real this time next week, maybe there. Moving the engine forward in the Moo is out of the question, and don't know if it'll work on the JE in it anyway. You've ridden in the Moo Omar, and while not hitting full throttle, you know damn well I'm not near triple digits! (80's, oh yeah!).
More likely I'll try one in the Hallett Brad sent down here. (We've kinda dubbed it the Bradinator unofficially). Don't see the need in the Moo, no loader or stuffer, and I'm not real sure even with impeller changes and cav plates she's capable of triple digits, but I'm hoping to get closer to 90. And no real need in the Saguaro, which I plan to be MUCH milder than the Moo. The engine/pump combination for the Hallett dealio I've narrowed down to two directions (Neither is traditional, but none of my boats are), and neither of which is remotely sane or economical.
After the reverse bucket incident at Big River, I can easily see how an engine failure can toss you outta the boat! Damn near happened to me on that deal, tho this device wouldn'ta done a thing about that.
