I have a 1978 140HP engine and I just got a new tachometer for it. The back has a switch with 4 cyl, 6 cyl, 8 cyl, and 12 pole<br /><br />Would I set it to 12 pole for my boat.<br /><br />Thank you for your advice,<br />Jeremy
I just baught a set of gauges on ebay. The tack says on teh back<br />Engine<br />4 cyl<br />6 cyl<br />8 cyl<br />12 Pole<br />(OB ALT)<br /><br />What should I set it to for aan outboard tach?<br /><br />Thaks
