Engine runs like new again!

Swapped in these pistons on my Yamaha outboard and wow—the difference is night and day. Engine feels super smooth, revs clean, and runs like it did when it was new. Installation took some careful work, but nothing too crazy if you’ve done a bit of engine maintenance before. Definitely feels like I got my power back. Super happy with this purchase—my boat is ready for the water again!
