Good To Know

Q: Will this valve fit all Johnson and Evinrude outboards? A: It replaces genuine OMC part numbers 0435340, 5030877, and 5008034 used on many older models; verify your existing valve part number to confirm.

Q: Can I install it myself? A: Yes, the valve threads into the trim cylinder and requires only a wrench; be sure to bleed the system afterward to remove air.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
