How much HP are you looking to add ? I don't think you'll find an 02 sensor on a stock motor. I think you would be best off using a plate under each throttle body and a stand alone fuel system for the n02.

GPM, I ran 100hp nozzles on the old boat but would like to jump up to 150 for the new engines; plan to use a wet system with fogger nozzles...

You can get fuel from either end of the rail. The end by the dist has a threaded plug and the front end has a schrader valve to release pressure manually.

I think you forgot about the rev limiters. If the boat is propped correctly now it's not going to run any faster mph it will just hit the limiter faster. And if you put the big props on, it won't get out of it's own way unless you are on the juice. When I ran it on my drag car a 10 lb bottle would last 120 seconds , makes for a real short boat ride. Just my .02 Jeff
