I have a 1973 Searay 19 ft. with a 302 Mercrusier V-8 main engine. I have mounted a 1999 Yamaha F 9.9 Kicker motor for trolling. The fuel tank is in the Bow and I would like to run both motors from the main tank, is this possible and what do I need to do? Also is this a good move or would I be better off with a separate fuel tank for the Kicker?
