2018 Yamaha Offshore 4.2L V6 F250NCA Outboard Motor

Yamaha's 2018 Offshore 4.2L V6, listed as F250NCA with model code F250XCA, puts 250 hp through a 4169 cc V6 on a 25-inch shaft, aimed at dual and center-console boats stepping up horsepower and displacement without re-rigging for a bigger block.

Rigging checks

Steering here is digital rather than mechanical cable, so make sure the control setup matches before ordering. Dry weight is 562 lbs, and this V6 is built to run in either fresh or salt water.

Charging and cooling

The alternator produces 50 to 70 amps depending on load, enough for a boat full of electronics and a multi-engine Command Link Plus display with 6-inch or 7-inch screen options. An optional Y-COP theft-deterrent system can disable ignition and fuel while docked. Dual pairs of water inlets on the front and sides of the lower unit keep cooling steady across a range of conditions and loads.

Rigging numbers

Trim runs from -3 to +16 degrees, and tilt reaches 67 degrees. The gear ratio is 1.75:1, shifting forward, neutral and reverse, and the rpm band at full throttle tops out near 6000.

What oil does it use? Yamalube 4M, with the wet sump holding 6.3 liters with a filter or 6 liters without. Is there a theft-deterrent option? Yes, the optional Y-COP system disables ignition and fuel while the boat is docked.
