I have a 2006 220 select with 350mag and bravo three drive. It is very slow getting up on plane. The engine doesn't seem to "wind up". The tach climbs very slowly several seconds (maybe 8-10 or more) until the boat climbs out of the hole and allows the engine to turn it's max rpm. The dealers says it should do better but offers no solution. Just wondering if I'm imagining things or if I really do have a problem and just what the fix is.
