    No the 462 is just a verification # kinda thing. If ur doin a full link and sync u will need tdc guage. If not u want the timin light to hit on 22ish off #1 while cranking with throttle wide open If u r tryin make sure the adjustable pointer is correct then u need tdc guage

    I pulled the plugs and rotated the flywheel until it came up to its highest point, marked that, and then when it sat at the tdc area for that short time, I marked the end of that. I favored the coming up point vs the starting down point and checked my pointer and it was dead on 0 degrees. Should I set it at 22 degrees wot from this point, or should I go more in depth in finding my tdc?

    That's fine for what ur doin. Yes 22 once u got 0 and it's on (like u got it) lock pointer and use very top screw on throtlle/timin arm to get 22 while cranking with plugs out and wot. Also pull saftey kill switch so it will kill all fire while cranking with plugs out. Hope this makes sense

    The .462 is used to accurately set the timing pointer, by folowing the procedure in the link and sync. You can also use .150 and make sure pointer is at 25° btdc. Using tdc to adjust pointer is not a good system, if it was Mercury would not bother with the .462 method.

    I'm not, however I'm willing to invest in a dial indicator if that's the proper way to do it. Just trying to understand how it's done fully before I make any adjustments or testing anything

    If you dont have the tools, manual or understanding. Dont touch it, one or 2 degrees is the difference between life and death.

    I bought the motor blown up, and want to prevent it from melting down again. I would like to have it set the proper way, to eliminate timing as a reason it blew. I suspect it was set at tdc and then 25 degrees. Either way, I plan to lower it a degree or two off the spec. I'll sacrifice power for more reliability.

    This is the first I've heard of the .462 method - all of my previous outboards have been omc. I'm eager and wanting to learn how to do it right.

    In my head, the reason for the .462 is because that's a set static point in the piston travel, and the piston hovers at tdc long enough that there is actually a few degrees difference from beginning of tdc to when it begins its descent. Is this correct?

    Replaced water pump, thermostats. Gave the block a real good flush with about 70 psi of water. Left head ran approx 135, 150, 152 top to bottom and right head was 140, 160, 158. I'm assuming these temps are ok? Is it normal for the pee indicator to get stronger as the thermostats open? Eating lunch and will then be checking timing with my new dial indicator

    Normal to see a trickle of water out the tell tale at idle untill stats open, may see it change back and forth at idle as stats open and close. If reved up at idle will see flow when poppet opens.

    another thing i ran into - hooked the tach up and it only works at idle - its very jumpy at any rpm above - im assuming the voltage regulator needs replaced?

    I set the idle on the hose at approx 1100 - is this close?
