SeaStar Terminator 400R V10 | Racing Outboard Engine

Once again, Today at SeaStar Marine, We introduce to you, the 400R V10 Outboard.

The 400R, a racing engine, is derived from our popular and well received Terminator 400 HP V10 engine. This engine uses a race tuned variant of the 5.8L XCQV 400 HP V10, to produce more torque for high end and racing applications.

Like the other existing SeaStar racing series outboards, the 400R utilizes SeaStar’s striking and effective racing core + our Hyperion XT lower gearcase, gripping the water and keeping your boat planted at high speeds.
