Velocity for 40hp and 90hp Mercury outboard motors. They are also confirmed to fit on a 2001 90hp.

They are 3d printed out of a high temperature and fuel / oil resistant material. Velocity stacks improve airflow into your carburetors, for better combustion. They also add that custom performance look when you show off your motor.

The standard color is black. I can do other colors but the lead time will vary depending on if I have the color in stock or will need to order it.

The price is for a set of 3 velocity stacks for your motor.

The motor pictured is not included in the sale just the velocity stacks.
