Plus-Series EngineHot Tested by supplying fuel and coolant so technicians can perform a series of live-running tests for quality assurance. All engines are completely remanufactured and include exhaust manifolds, fuel, electrical and ignition systems so they are ready to rig into a boat.

Considerations:To avoid the expense of a fully-dressed complete engine, the following items (if in good condition) need to be transferred from the original engine overto the replacement engine: exhaust manifolds, risers, starter motor, alternator, pulleys hoses and beltsInstalling a partially dressed engine into a 1981 or earlier application would not be recommended. Due to the shift bracket that contains a reverse lockmechanism, it would be extremely difficult and expensive to accomplish this upgradeThis product category may require a Core/Container Deposit.
