QUOTE=muc;n10263952]You won't be happy with it because running this engine like you are "lugging it" will cause the valves to tulip or burn out the head gasket.
I recommend more testing, a proper compression test both cranking and running, maybe a cylinder balance test.
You are low on power or there is something wrong with the hull.
This wasn't a good year for Chris Craft and this model in particular was kind of problematic.
Maybe hull is waterlogged?[/QUOTE]
Muc is right, I have the same engine and drive ratio and was running F4 set and ended up with some tulliped intake valves. It was running around 4300 rpm max. Switched to F3 set.
