The listed compression is 180–190 PSI, giving buyers an important reference point when evaluating the engine’s mechanical condition.

Engine Hours

Engine Hours: 550 hours

The supplied listing information specifically reports 950.0 hours, and this figure is included in the product specifications.

Shaft & Lower Unit

This F350XCB uses a 25-inch XL / extra-long shaft and features a counter-rotating left-hand lower unit.

Counter rotation can be particularly useful in multi-engine applications where engines are configured to rotate in opposite directions to improve handling and overall boat balance.

Buyers should confirm their boat’s required shaft length and lower-unit configuration before ordering.

Electric Start, Trim & Steering

The engine is equipped with:

• Electric Start
• Power Trim & Tilt
• Remote Steering

These features provide convenient starting, adjustable engine positioning, and helm-based control.

Propeller & Controls

A stainless-steel propeller is included with the package.

The listing also includes a brand-new Yamaha DEC top-mount control box, providing a modern control solution for the engine’s electronic control system.

The original source information notes that a gauge, harness, and key switch were still required. Because Sowell supplies its motors as complete mount-and-run packages, the applicable gauge, wiring harness, key switch, and required installation components are included in the Sowell-supplied configuration so the customer can complete a fresh installation without having to source essential components separately.

Complete Mount-and-Run Package

Sowell supplies this Yamaha F350 as a complete mount-and-run package.

The supplied configuration is prepared with the applicable engine controls, rigging, propeller, electrical components, starting controls, mounting hardware, and other installation components required for the intended setup.

This gives the buyer a more complete installation solution and simplifies the process of getting the outboard properly mounted, connected, and ready for operation.

Before purchasing, verify that your boat is properly rated and configured for a 350 HP outboard.

Important compatibility considerations include:

• Maximum horsepower rating
• Transom weight capacity
• 25-inch shaft requirement
• Counter-rotation requirements

• DEC control compatibility
• Electrical system requirements
• Gauge and instrumentation requirements
• Mounting arrangement

Professional installation is recommended to ensure the engine, controls, steering, electrical system, and rigging are properly configured.
