Tachometer Guide (Gas Inboard, Stern Drive) Teleflex 6K, 7K or 8K RPM Tachometers and Tachometer/Hourmeters are suitable for use with gas engines with fac to ry-installed ignition systems, except: 1960’s vintage Mercruisers with Thunder bolt I ignition, and Indmar LT-1 engines. Pilot II (French) IS0161a — Pilot II Owner’s Manual in French. Connect Master Tach and start engine. At about 1,500-2,000 RPM, use a jeweller’s screwdriver to carefully adjust the potentiometer in the «CAL» hole (about 10 o’clock on the rear of the tach), bringing the tachometer into agreement with the Master Tach. Rust buildup between the teeth can cause signal loss from the sender.


Connect «IGN» to «IGN», «GND» to «GND», etc. NOTE: mixing brands/types (such as 2-wire/3-wire, see paragraph 2 above) may cause problems. Self-powered, keeps total run hours or RPM displayed at all times. Fulfilment by Amazon (FBA) is a service we offer sellers that lets them store their products in Amazon’s fulfilment centres, and we directly pack, ship, and provide customer service for these products. Dual stations: the sender will drive two tachometers.

Tachometer switch arrow should be pointed at 4C, 6C or 8C to correspond to the number of engine cylinders. When tachometer is first turned on, pointer must go to zero 50 RPM. If not, check connections (if OK, tachometer is probably faulty). Voltages with engine running should be: IGN to GND terminal: 12 VDC minimum; SEND to GND terminal: 5 VAC minimum. Alternator must have an AC tap, usually marked «AC», «R» or «W». If there’s no tap, a local alternator repair shop can usually add one at a small cost.
