What is the compression range suppose to be.

As long as they aren't below 80-90psi or so and within 10% of each other.

V-6 i didn't know about the V-4

 

[bob johnson]

seems the v4s had compression in the 130s, while the v6s usually only had compression maybe up to 110.......the manual doesn't list compression as best I can tell.... I picked up a 1999 V6 150 hp... and the compressions were 93-95.... after I mounted to the boat I took it to a dealership who put it on the dyno and said it was running at 100% of new...as far as putting power to the prop.......
