Re: foam and what its for
good deal. im not saying your wrong in any means lol ok but i think i will put foam in them just incase i dont make it water tight and also if i back into something and crack it they well still work. i was reading another post about theis pods and they were saying not to taper the side where the motor can turn from side to side something about cavitation. what is cavitation and how does it affect the prop
1957evinrude: - Yes, your idea will work. It will work better if you do not taper the back ends down like that. You see, as soon as that thin tapered back edge goes underwater you will not be adding any more buoyancy the deeper they go. If you make the top surface pretty parallel to the bottom (full thickness all the way back) then the deeper they are submerged, the more water is displaced = adding buoyancy, which keeps the stern from dropping. Also, these do not need to be full of foam. If you make them out of fairly thin plywood (empty & watertight) they will work better than if you do the same thing and fill them with foam (because they weigh less empty).
