Do you know if the current Skater 21 has a center pad or not? What do you think an honest top end is for that boat (lightly loaded with top-end prop) with a Merc 300X ProMax (supposedly about 325-330 HP)? What modifications were necessary to make the turbo work properly? I know that Bob Bergeron developed it at Land and Sea. Has anyone ever developed a belt-driven supercharger for an outboard? Might be next since we now have belt-driven Optimax injection systems. Would not need as much "plumbing" as a turbo. My first post. Looks like a good site. Thanks!
