Product Details

The WSM 100-15K is a standard bore replacement piston designed for Mercury marine outboard engines with a 2.875-inch bore diameter. This precision-engineered piston is manufactured to OEM specifications to ensure reliable performance and proper fitment in compatible Mercury powerheads.

Key Features:

  • Standard bore size: 2.875 inches (73.025mm)
  • Manufactured to meet or exceed OEM specifications
  • Precision-machined for optimal compression and ring seal
  • Direct replacement for Mercury original equipment pistons
  • Designed for durability in marine environments

WSM pistons are constructed from high-quality aluminum alloy with proper ring groove dimensions and skirt clearances for reliable operation. This standard bore piston is ideal for engine rebuilds where cylinder walls are within factory specifications and do not require boring.

all good so far

Easy to find what we were looking for. Great comparison pricing.

Easy checkout

great part price but there has to be a way to do cheaper shipping...

Easy to use website and low prices.

A++++++++++

Certainly the lowest price for the exact same product that other websites offer. I ordered on Monday and got half of my order delivered just two days later. You can't beat that service. It's also great to call and get a real live person on the phone in a matter of seconds. Will definitely order from them again.

Authentic, hard to find item listed for the least expensive price online! Good customer service and fast shipping time!!
