An HEI distributor will not need a ballast resistor. It is designed to run on full voltage. The ignition module should also get full voltage. The ignition module should have some thermal paste on the bottom where it mounts to a metal plate to conduct heat away from it. If there isn't paste, it...
I don't know what your plans are for the boat, what condition it's in, or how much you plan to use it, but it's pretty hard to beat bang for the buck when you can get a good, relatively low mile engine from a truck for under $1000, put brass freeze plug in it, replace head bolts and gaskets if...
In the driveway, put the plug in and fill the bilge with water and see where it leaks out the back. Just be careful not to submerge anything you don't want wet.

Personally, I would have checked the classifieds or junkyard for a...
I have had a broken oil pump intermediate shaft that resulted in no oil pressure. Oil pickup tube can fall off. Pull the dizzy and check intermediate shaft. And make sure dizzy shaft is intact
Take a straight edge like a 2 foot bubble level or a carpenter's square across the pulleys edge. Make sure they are lined up with each other and not sitting crooked
Make sure your pulleys are properly aligned. Put a straight edge across them and they should all line up. If not, they are improperly mounted or wrong pulleys or accessories are not correct or improperly mounted.
Could be head gasket, intake manifold gasket, cracked block etc. First time out this year? Overheated? Improper winterization? If you think the motor can be saved you need to drain/flush all the milkshake out ASAP! I would drain what I can and fill the block all the way up with diesel fuel and...
The one above the oil filter is a oil pressure port generally used for an oil pressure safety switch if a marine application, often not used in automotive application. Other holes, if going to coolant passages can be coolant temp or drain plugs. If blind holes, may be for knock sensor. Just make...
