Not a rumor- supposedly it will be debuted at the Miami show. Original specs were 250hp, but I had heard the dyno pull was 300hp.Originally posted by dreamboater
I have heard rumor on another sight of a 4 stroke turbo charged OB motor by merc. Havent heard much since, so that might have been just a rumor.
It is supercharged at a very low boost level; possible growth to 400hp. Not sure of octane requirement.
This is Mercs baby- no Yamaha influences as in previous 4-strokes. The torque on this engine is reported to be enormous.
