- Cobra Jet Steering for Mercury Optimax Engines
Attachments
Details
Many boat manufacturers have used Mercury jet drives. Some of them are Sea-Doo, Polaris, Sugar Sand, and of course Mercury. Cobra Jet Steering offers steering for two different Mercury jet drives.
The first, designed for Mercury Optimax drives will fit any boat using the Optimax jet drive and also the other Mercury 6-cylinder jet drive applications and the Mercury jet drive equipped with a Cummins diesel.
The second is a special custom made set for the 90hp 3-cylinder and 120hp 4-cylinder Mercury Force Sport Jet. If you need steering for these units, click HERE.
