This might be difficult to get a clear answer to, but I thought I would post and see your thoughts. Last weekend when using my boat, its a Calabria Cal-Air Direct Drive, with Merc 350 Tow Sports. When hitting the throttle to start skiing the boat would accelerate as normal but then seemed like it slipped or missed for a moment and then accelerate as normal again. If I hit the throttle a little lighter it would not do this. Any thoughts?
