Can I trust the TDC marking on my flywheel?

[astampfel]

I'm going through my tech manual and it tells me how to determine TDC from my number one cylinder. I have a 1990 90 Hp Johnson VJ90LESB. But, I have had my flywheel off to replace my rectifier/voltage regulator and there is a key that locks in the clocking of my flywheel. So, I'm thinking that TDC is set at the factory. Am I safe to assume that TDC is correct, or should I get a dial indicator and measure it myself?

if you are adjusting timing, never assume the pointer is correct until you check it. Who knows who has messed with it in the past.....

If the center hub magnet has not ever moved then the marks on the flywheel are in the right place. As stated, never assume the pointer is correct. It's way to easy to check & adjust if needed.
