Well I have a 16' 1976 Charger Deckboat with a 1981, 115 hp Evinrude. Mounted on the Evinrude is a Minnkota trolling motor, EM 48. The trolling motor is 24 V and is blowing the fuse after about 1 minute of use. <br /><br />First trip out we used the trolling motor with no problems. Second and Third trip out the fuse blew. The fuse is rated at 20 amps. This is what was installed prior to me buying the boat.<br /><br />The fuse that blows is one of two located on the bow-mounted control panel. This panel controls the tilt/trim for the Evirude, the charging of the batteries, selection of 12V or 24V, and power to the trolling motor.<br /><br />Any thoughts as to why this is happening?
