    SEI Marine replacement parts?

    Does anyone know if SEI Marine makes quality internal parts? Looking to replace a water pump kit and their model is $50 cheaper than the OEM.

    I can’t speak to their quality per say but, is 50 bucks worth that chance?

    Not worth it. I always use OEM and SEI stuff is junk.

    Chris- you didn't say what engine you're working on, but some of the more common pumps aren't much over $50 for a new OEM.

    I do see that they are constantly making more and more different things... but so far have yet to find any that I would want to have to stand behind.
