Furuno NAVpilot-300 vs Garmin Reactor 40 Hydraulic

These two dominate the serious end of the Australian trailer-boat and sportsfisher market. Both are hydraulic autopilots built for outboard and sterndrive boats, both do without a rudder feedback sensor, and both are sold through the tackle-and-electronics shops that plate-alloy boat owners already frequent.

They solve the same problem differently. Garmin's Shadow Drive — definition senses you turning the wheel and hands control back automatically. Furuno's Safe Helm — definition does the same and then adds Power Assist — definition, which turns the pump into power steering at low speed. Garmin folds everything into the GPSMAP; Furuno gives you a dedicated colour head and a gesture remote you can wave.

Record the engine and steering models, cylinder details and whether the steering uses a conventional hydraulic circuit or an electronically integrated arrangement. Engine horsepower and boat length are insufficient to establish compatibility. Ask for the manufacturer-supported configuration for the exact vessel.

The Reactor 40 family includes different packages, so the quote should name its pump or interface rather than simply saying Garmin autopilot. Apply the same scrutiny to the NAVpilot-300 proposal, including control components and any equipment retained from the boat.

Think through who operates the helm while another crew member handles fishing equipment. Compare the location and supported use of fixed controls and remotes, including the fallback if a remote is unavailable. A convenient control feature does not remove the need for an active watch.

Agree which operating conditions can be demonstrated during commissioning and record any conditions not tested. Ask how the pilot responds to mode changes and how manual takeover works. Avoid choosing on an assumed low-speed or rough-water performance advantage without evidence for the installed configuration.
