So recently I got egg on my face on another post about something or other to do with another owners Merc 350 mpi. He said his manual stated the top of the Rev range was 5200. I argued that it should be 5000. Turns out that the exception to the rule is with one type of this model of 350 mpi. The fresh water cooled version. It does indeed run to 5200.

Why is there a difference? Both quote the same power too. What’s going on. What’s the logic here. Maybe a simple answer ? Just been bugging me.

Cheers

A Mod can move the thread to the Merc section

The first Gen MPI were at 4800 and only the inboard Ski versions 350 at 5000 and 6.2 Black Scorpion (377/6.2) was at 5200

The next Gen MPI gave the 350 I/O at 5000 and 6.2 at 5200 for both Inboard and I/O

Most changes come from changing components and better balancing
