It's been a while since I changed the plugs, wires, cap and rotor, but plan to do so in the Spring. Is there also a 'Condensor', in the distributor housing?
That being said, can I purchase these parts from my local Auto Parts store, or do I have to go a marine dealer and pay twice as much ! Is there any difference between my 4.2L Merc, versus the same engine in an automobile?

You mentioned 'rubber in the propellar', I'm not sure what you mean ?
I don't have any rubber on my prop ?
I have 2 props, and hey are both aluminum.
Thanks for the feedback, much appreciated !

Plugs are marine rated and made of stainless steel. I would think the cap and rotor would have to be marine rated as well, considering the sparks they deal with. Plug wires should be the same as a car. I doubt you have a points style ignition, therefore, there's probably no rotor. NAPA sells marine parts, BTW. That said, you can never go wrong with Mercruiser OEM stuff, it is well made.
Most Alpha props have a rubber coupling in the hub that helps prevent damage to the propshaft from rock strikes. It fits tightly between the splined inner section and the aluminum outer section. They can and do fail. I strongly suspect that's the culprit here. A prop shop can "re-hub" the prop for little money.
