I have a prop with 3 fins, probably original type. Is there a certain replacement that is better for pulling the kids around on the tube etc. type/place to get???<br /><br />Also the trim is a manually set and is set to the very last holes on the bracket underneath. Is there an optimmum place to set it. Boat does not flatten right out when towing a tube. Just need some info or direction as to setting it correctly<br /><br />Thankx in advance
