This is my first boat so I am not an expert, but in the same day this happened.<br /><br />My speedometer is sitting at zero and the trim won't go up. I can press the Trailer button and the engine comes all the way up though, so It sounds like an electrical issue?<br /><br />1991 Larson 170 All-American<br />Merccruiser Sterndrive.<br /><br />Can you guys give me some pointers on where to start looking?<br /><br />Thanks,<br />ScAndal
