I need to replace the fuses in the boat I just bought, and some are missing. What fuses should I use for the following:<br />Bilge pump<br />Blower<br />Horn<br />Nav lights<br />Ignition.<br /><br />I don't see the info in my book.<br />Boat is 1984 120 Mercruiser, 4 cyl, but I doubt that matters.
