what would be the best dia pipe for a 115hp mercury with the fuel tank in the bow ? and the length would be around the 5 m . and would the fuel pump cope with this set up ? any comments or thoughs on this will be greatfully recieved ....thanks
I would suggest that you confirm that your motor is not experiencing any fuel starvation issues with that new setup. Fuel starvation can result in a lean fuel/air mixture causing serious engine failure. Mercury published an Advisory that describes how to test for fuel starvation. You only need a vacuum gauge, several inches of extra fuel hose, and a t-connector to do the recommended tests. See link below.
