Recieved my foil today for my Mercury 250xs with a sportmaster that CHRIS made for me . Looks fantastic the man did a great job. It is like a mirrow on top can't wait to put it on. Question if anyone can help. Any tips on installing it would be helpful the plastic one that's on their now is on the top of the cavitation plate this one goes on the bottom i'am pretty sure just need to make sure before i mount it And does it need any spacers between the foil & plate. Again big thanks to CHRIS for a fantastic product.
