the tack will be off by 2x since the 2stroke fires 2x as often... and the tachs
pick up on when the coil sends voltate..

at least; that's my take on it.... as compared to trying to rig a car tach to a
2cycle race bike.

Any reason I can't use a 4 cyl automotive tach for my 4 cyl o/b motor? The
auto engine is 4 cycle, and the boat engine is 2 cycle.

I'm just wondering what it take to make it useable on the o/b.
