Right part for my engine
Can’t go wrong with sierra parts. Great part for the price. Comes wrapped in plastic so it won’t get rusty. A+

Boats back to running good
This was all it took to get my 1997 Four Winns Horizon 200 back to starting and running like a champ. Before replacing this, the boat would struggle to start and stay running. Still cant believe that's all it was. Slower shipping than I would have liked but it is what it is.

1994 Cobalt 220 with 5.7 GI Volvo Penta
Perfect for the older Volvo Penta 5.7 GI. I do maintenance every year after taking the boat out of storage. This is a simple filter, located right in the front of the engine. Swapping it out takes 5min.
