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.

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.
