Trying to get info on coolant drain plugs for 496 ho,read a lot of forums &say that on side of block down by oil pan ,only found 1 on port side( think it's the oil galley plug,,,,,,just trying to change antifreeze out ,older motor, any help would be helpful!!!!!!

Also have checked both sides of block ,found no plugs,is it possible this motor doesn't have them? 2001.? What other way is good?,just remove H.E.,hoses?

Use the search, I recal Raylar stating the size and location.

Yes!!!,raylar was correct,very,very hard to "see" them ,got them out!,any suggestions on type of thread sealant to reinstall with?,looked like white pipe dope from, possible factory sealant originals:

We find that when we remove these plugs there always seems to be enough white teflon pipe dope on them for a reseal. If there is still white thread seallant on the plugs, tighten them back in nice and tight and they won't leak.

Best Regards,
Ray @ Raylar

Thanks raylar , also had small amount of sea water come out of lower unit pickup,(bravo-1),during coolant change out. Coolant pressure in motor while sitting cold ? Heat exchanger issue possible?,,,,,,or maybe nothing at all ,,,,,,?any idea?

Another topic,,,,,changing out sea water pump pulley ,(long story) trying to get idea on how far to drive pulley on pump shaft ,as for very hard spot in boat if pulley is not aligned correct with other pulleys after install,
( new pump -comes with no pulley)lol,so have no ref to go by.
Any help on this issue would be great!

just press it on the shaft till the pulley is flush with end of the shaft, loosely attach and check alignment with a straight edge along the front of the other pulleys, pressing the pulley this far worked perfect when i changed to the stainless pump

Thanks for reply on pulley,for straight edge ,I have about 1" to the bulkhead off face of pulley's, any suggestion's on what to use for straight edge?

anything that is known to be straight will work, i used a 2 foot level on its side, though it is about an inch thick, you could also use a yard stick as long as its straight
