i've been having trouble getting my boat to start. it's a 40 hp force (made by merc). the problem i'm having is that when i go to start it, it seems like it's not getting enough juice. i put a brand new batterie in it and still didn't help. when you turn the ignition if you hold it sometimes it will fire up after about 5 sec. i just can't figure it out. also my fish finder, it's a hummignbird not sure what type but it reads depht and bottom contour just fine but it will not pick up fish. i thought it was something in the menu or settings but couldn't get it any advice would be great. i'm really hopeing to get it fixed so i can get out a few more times before i have to put it up for the winter.
