Wildman,
You mentioned in a previous post your red line is 6400....Mercury is saying 6100...My friend, Bullhead Bully has 300xs twins and he gets 6100. Did you mod something to go 6400? My 300xs goes 6100 as well....
Ok I looked at the motor mount and it gives you a max RPM of 6400. The Manual on page 33 has the sportmaster 20 " at 6350 max . And mine is shuting down right at 6100 to 6200 I will call Merc and find out where it should be . Both of my motors are the same ,it is not a big deal but I do want to know what is right number. Scott did you already call Merc?
