Proptop,
I mounted the engines as high as I could to combat spray, works well but the mufflers kick up some water while taxiing at low speeds and that's not a problem. If you do a twin, be sure to choose your fuel tanks BEFORE you design your nacelle's and in the case of the SeaMaster, you do not need to remove the bottom wing sheeting or the leading edge from between the ribs .
Just remove the sheeting between the ribs at the end of the wing center section sheeting and start cutting paper templates till you find the shape you want.
LOL.
