All parts are OEM exact fit. Orders arrive within 3 days in Hawaii. Couldn't be happier. Look forward to purchasing in the future.

Problem fixed: Timer Base

I'm not a boat mechanic with all the specialty tools. With that said, the repair took longer than it should have, only because I had to make a tool to hold the flywheel from turning while pulling it off and torquing to specs when putting it back together. Other than that the repair was straight forward. No problems.
