I was looking at the rules and Division 3 says "Stock Gearcase" for outboards. I have a 225 ProMax with a CLE. That is the stock gearcase for that motor. Would that run in Div. 3?

Also, what are rules regarding bolt-on mods? i.e. SVS, Light flywheel, 16 amp charging system, heads, reeds, exhaust tuner, exhaust adapter, etc.?
