Note: If you are installing the Enhancer Ignition on a late model Yamaha Watercraft and find that the
connector on the Enhancers White wire does not match the connector on the factory White/
Red wire, then you need to install the supplied White jumper wire. This jumper will allow the
connectors on the White and White/Red wires to match (See the insert in Figure1).
ADJUSTING THE REV LIMITER
The adjustable Rev Limiting function of the Enhancer Ignition is pre-set at the factory at 8,000 rpm.
Its adjustable range is from 5,500-9,000 rpm. With this in mind, every 1/3 turn is approximately 1,100
rpm.
Note: While we feel 8,000 RPM is a safe setting it is the customer’s responsibility to know the
limits of their engine.
1. Using an 8mm wrench, loosen the lock-down nut on the potentiometer shaft by turning it
counterclockwise (Figure 2).
2. To increase the rpm limit, turn the potentiometer shaft clockwise. If you turn the shaft until it stops,
the rev limit will be set at 9,000 rpm. To decrease the rpm limit, turn the shaft counterclockwise.
If you turn the shaft until it stops, the rev limit will be set at 5,500 rpm.
Note: Do not force the adjusting shaft beyond its limit stops.

Note: Before starting the engine, make sure all wires and lines are mounted away from the engine
and exhaust.
