It's not popular in boats cuase you would have to run alot more prop to see the benefits of it, but you would never get out of the whole with it.

Nitrous works great, if you don't go crazy. However, it's expensive and doesn't last long. I just like the novelty of it. I gain a solid 5 MPH (79-84 MPH) with an NOS Sniper kit set at 125 HP on a SBC with 500 HP.

I had a Talon 22' tunnel hull with twin Mercury High Performance outboards. They were carburated and rated at 245HP a piece. Went with a nitrous kit from Hydrodynamics. I sent them the manifolds and they plumbed them with the spray bars and I used a remote fuel cell for alcohol as the enrichment fuel with dedicated electric fuel pumps. Added 110HP per engine (710HP total).

Had the boat 8 years (the last four years with nitrous) and never had a nitrous related engine failure. Invest in pyrometers (exhaust gas temperature gauges) and keep an eye on fuel pressure. This boat was a BLAST. 40 to 80mph in less than 3 seconds on the bottle. Topped out at 110mph turning 28" clevers. I ran the smaller props for acceleration and handling.

Pre-daughter - the wife loved speed. Post-daughter - the mom said bye-bye Talon....

Had NOS on a 20' Checkmate with a SBC, loved it at the time, hit the button and away you went.....for about a minute and $60. The next boat I supercharged, best investment I ever made, that supercharger never ran out!
