SEI MARINE PRODUCTS - SE418 V6 4 Stroke 90 Degree Gearcase Counter Rotation 2.0 Gear Ratio 25 Driveshaft

Engine

Our SE418 replaces most Yamaha V6 90 Degree Counter Rotation 2 and 4 stroke lower units.
Our SE416 and SE418 will not work on any 250 HP 4 stroke engines.
To determine if you have a counter rotation unit on your twin engine boat, it is easiest to look at the props. If the props are identical orientation, then they are both standards. If the prop blades are opposite, then the port should be a counter rotation.
This lower unit typically ships within 24-48 hours.
Replaces OE #: 64P-45300-10-8D

All of our lower units come with a three year fault-free warranty. They are manufactured in Oldsmar, FL, built up to OEM specifications and they are an affordable, high quality alternative.
