3137S2 Wiseco .020 Piston STBD for Mercury 140 150 175 200 HP

Simple as it is, a piston is one of the most important items inside an engine. To ensure the piston is in good usable condition, we take the extra steps with each piston we sell:

• Professionally cleaned and inspected
• All carbon complete removed.
• Make sure the is no raised dings.

Matched against the standards of our competitors who pull it out of the engine and throw it in a bucket, the piston you receive from us won’t even compare.  Purchase this piston and as many as you need with absolute confidence!  

This does come with two rings, and the wrist pin.
