Mercury SeaPro 300 Pair: Details

The 300XXL SeaPro pair is a Mercury SeaPro 300 pair: two matched used SeaPro 300 HP outboards with 30 inch extra extra long shafts and Digital Throttle and Shift. They're sold together as a twin rig for $17,500.

What SeaPro Is

SeaPro is Mercury's commercial outboard line, built for boats that work long hours: charter, fishing, patrol, survey and ferry boats. SeaPro engines are calibrated and built with durability in mind, so they're a strong choice if your boat earns its keep. A 30 inch shaft suits larger offshore and commercial hulls with tall transoms.

Why Buy a Matched Pair

A matched pair is the same model, setup and generation, so the two engines run in sync, wear evenly and use the same parts and service schedule. For a twin repower, that's simpler and usually cheaper than sourcing two separate engines. Make sure your boat is set up for twins with the right rotation, rigging and DTS controls.
