Most outboard and sterndrive boats steer hydraulically, and these packs add a small pump to the steering lines. The pump has to match your steering cylinder, so check the cylinder range before the boat length. Raymarine lists it in cubic centimeters, and Garmin and Simrad packs publish a range too. Prices here run from about $1,275 to $4,400.
