Some rumors and coments do not have this new catalyst engine performing as planned. Lets hope we get some more feedback from actual high performance boats like this one.
Think back on how the 1970-1975 cars where with the first new emissions systems, especially performance results.
As for modifying these engines for more power. I would forget about that for a while? These new catalyst controlled OBD IIIM engines have three year warranties on the emissions systems and engine and cannot be touched during that period - PERIOD! As for who as a manufacturer aftermarket or otherwise wants to take on the laws and EPA-State Emissions will be a big issue.
My call, if you buy a boat with these engines, just sort of give up for now on any modifications for more power and live with the original performance and hoped for Reliability??
Want real big performance then order the Mercury Racing, or Ilmor engines for superior performance.
Very Nice boat and I sincerly hope the new owner gets a nice reliable package with reasonable performance, especially when you consider the healthy price tag.
