Doing a two piece transom plate, should the seam of the two plates run vertical or horizontal as in picture. Someone told me if i run horizontal it could break my seal in the plates due too pump flex. Also would like too know how far apart should i put bolt holes for transom plate too transom. Any one have any pictures of one done. Thanks Z racing
