Timing Issues -- 470

[Jon_912]

So I have a Mercruiser 470 and I've go it where it will run, but only when I have some throttle on it. I have looked at it with a timing light and the timing is out. It is supposed to be 8 Deg. BTDC and when I tested it, the lines on the block and fly wheel were way off. So anyways I start to slightly turn the distributor to line them up, and the closer it gets to being lined up, the more the motor bogs down, eventually shutting off before I can get them lined up. Any suggestions?

Did you check your dwell and the points? Also, how's the idle mixture screws? I am sure that some of the real experts will chime in something more to check.

Just so you know, the new recommended timing for the 470 is 4BTDC.

hmm, I will check the points, what is the "dwell?"

I checked the firing order thats stamped on the block and its "1,3,4,2"

the outer part of the balancer could have slipped from the inner hub.
