Ok, so I have a 21' 1978 Omega Open Bow Jet Boat with a Jacuzzi WJ (doesn't look like it has had any work done to it, but I'm gonna open it up to verify) and I just got a Twin Turbo BBC that I was thinking of putting in there in until I have a faster hull that I want to drop the motor into. I am planning to strengthen the stringers with fiberglass cloth, a rail kit, and a pump brace. The question is if I have all my bases covered to put this engine in this boat. If necessary (Primarily to avoid any failure, secondarily to gain efficiency/MPH) I would like to either have the Jet worked or install an energizer kit in the future. Does anyone have personal experience with both? Will it handle that HP as it is if I don't plan on beating on it until the Jet has undergone some work? It ran pretty good (no GPS MPH taken) with a 400-450HP BBC previously.
I would like to hear some advice on what my best option is, and what is absolitely necessary to avoid any catastrophic failure. The goal is to have a pretty quick cruiser, as I am obviously not going to be racing with this boat. I just want to have a good cruiser and I'm sure I'll take the TT BBC engine out in favor of a small quick boat in the future. I don't want to dump a bunch of money into the Jet if it will hold up as is. I appreciate any input or advice. I will post pics soon of the boat and jet.
