With 4 valves per cylinder the valvetrain won't have to be as aggressive as our regular 2 valve setups which probably equals the 250 hr rebuild interval!
I'm not a diehard Merc fan but kudo's to merc for stepping up to the plate into the 4 valve arena! Question I have is if this is based of a GM engine or something new?
Also, I notice it's a short stroke engine...must turn some R's!!
(ps, I didn't read the article so maybe it's alread stated...too busy at work)
Not much different stroke than your everyday 556CI. Tall deck engine with that stroke will always turn some good rpms. :sifone:
