Hello Michael,

Would you happen to already have a set up? If so can i have the number for your helm so i can find that schematic for you? If you are looking for a schematic to purchase a hydraulic system please let me know the serial or model number and year of your engines.

Kind regards,
Mario

Need a hydraulic schematic of a helm driven system for twin 150 yamaha outboard engines

I’m trying to set up hydraulic steering for twin yamaha 115 outboards mounted on a barge, outboards are ten ft apart and each outboard is approximately 13 ft from the helm what parts do I need to accomplish this.

Looking for steering system for new twin 175 hp Suzuki outboards. Do you replace parts or whole system?
