Just as fleetwin and lindy stated, clean wire ends, dielectric grease, and the proper coil boots always work for me. I generally replace the ignition wires, but many just trim them back to expose fresh copper with good results. Dielectric grease is good because it will help prevent corrosion, and also helps prevent electrical leakage.
In regards to the coil/wire connector pins, the OMC style coils have plain spikes, whereas the Prufrex style coils have auger type connectors that require the wire to be screwed in. It seems as though all of the aftermarket overseas coils have the auger type connection these days. I recently had a motor with a set of good “spring green” OMC coils. The last person to work on it chose to skip installing the coil boots, then run it in salt water. The coils were fine but there was lots of corrosion at the coil spikes, and lots of cleaning to get them firing again.
While I’m at it, if you are short on the proper coil boots, marine heat shrink tube works well to seal up that very important connection.
