We have a 225 vindicator on a 1996 Stratos 201 pro XL with a 24 trophy Plus and no matter what we do to the PVS plugs or the engine height it will not wind up at hole shot it just barely climbs out of the hole my guess is that there is Exhaust escaping from around the barrel of the prop because of It’s smaller diameter than the lower units diameter . You would think that it would blow out but I think instead of the gases being shot up onto the blades by the pvs plugs it is just running along the root of the blades and still causing it to hook up well.The over hub ventilation causes low back pressure inside the barrel that would prevent the Pvs plugs from blowing gasses up onto the blades. This is just my theory we have ordered a cavitation ring for the trophy plus. Any ideas of why the prop is hooking up so well? Thanks
