Question for the group….so a Mechanic is on the boat, mains rumbling in idle, one of the tacks is reading 600-700, right where I want it. The other tach is reading 1000-1100, but the engine does not sound any different(faster idle) and the synchronizer is reading 12 o’clock…dead even. So the mechanic whips out a small gadget, walkie-talkie sized, with an pull-out antennae, and says….”yep dead on, 650 rpms”.
So two things…..obviously I have a bad tach, and what was the thing he had (I didn’t even think to ask him, duuuuh), I want one!
