Tried to find some posts dealing with my tach. I have a stratos mid 90's I think. We bought it from my wifes uncle and it was used about 30 hours when we bought it. The tach works only at idle. Is there a trouble shooting guide to check things, I saw diff posts about the rectifier ? maybe, not sure about boats. I'm still learning things. It has a 70 evinrude also - thanks Mike<br />Also, I'm trying to ID my trolling motor, It says on the pedal, BF2K 12v
