Now I got a lot of flak a couple months ago about using O2 sensors in marine
applications ( a statement was made that O2 sensors are only valuable for
emissions and catalyst health - which I personally do not agree with but am
not in a position to argue)

Comments on closed loop aftermarket MPFI marine applications???

You can do aftermarket SEFI, closed loop with O2 and other cool things
too. Costs money and effort, but it does work, and work well.

Vortec heads produce good low speed torque, but aren't suitable for
high-perf applications where more than 300 - 320 HP is needed.

The trouble is you're talking about a ski boat hull, so adding power
doesn't make much sense. If you like watersking AND going fast there
are alot of boats that would make you happier than a center-engine ski
boat. A Ski Boat does not have to be a flat-bottomed 45 mph inboard.
