Feels like I have a new motor again. No complaints!

Great replacement for my worn-out unit. Bolted right up and no issues with alignment. Running strong after 2 months on the water.

Excellent build, good packaging, and arrived on time. Would buy again.

I got the remanufactured version and honestly can’t tell the difference from new. Saved money and got great results.
Sarah Rodriguez –
Worked perfectly with my F90 outboard. Instructions would’ve helped, but still happy with it.

Been running this for over 40 hours with zero problems. Smooth and quiet.
Sarah Brown –
Had to swap shafts but support was helpful. Now runs great.

This lower unit brought my Yamaha back to life! Fit, finish, and function were all on point.
