Questions & Answers

Is this a genuine original part?

This is a premium quality aftermarket replacement part from Multiflex (Multisteer), manufactured to meet or exceed ISO 10592 international standards for boat steering systems.

How do I know if it is compatible?

This kit is designed for universal fitment on most major outboard brands. Ensure your engine is rated for a single cylinder system and that your splashwell has at least 560mm of width for the cylinder's "bullhorn" travel.

Can this kit be used for twin engine setups?

The OH-350 kit is designed for single-engine applications. For twin engines, you would require a secondary cylinder and a tie-bar kit, or a dedicated twin-engine hydraulic system (OH-700-T7).

Note: Please verify your engine horsepower and splashwell clearance before purchasing. For expert assistance, contact the 4boats.co.uk support team.
