Spark plugs and cap replacement interval

[Lou C]

It's easy to just ohm out your plug wires, not more that 1k ohms per foot of length is a good guide, and check the cap & rotor carefully with a bright flashlight for carbon tracking. Another trick I saw on Uncle Tony's Garage you tube is look in the cap terminals when checking wires, if a wire was not pushed all the way in when the cap was replaced, then the arcing could ruin the terminal on the wire and the one in the cap.

Gee, I thought my sterndrive ran well, also. I went fishing in the ocean and it blew so hard that saltwater from the bilge splashed up under the plastic cover, past the spark arrestor and stalled the engine. It started up and ran fine, but it spooked me, so I babied it all the way back into the bay. Once in the bay, I ran home at normal speed.

Subsequent to that, I replaced the rotor, cap and wires, for good measure. Unexpectedly, the motor ran a whole lot better.

Here is the bottom line......are you willing to carry spare parts, can you change these parts out on the water ? Do you have a kicker motor to get you back ? How far can you paddle your boat ? Consider the afore mentioned situations, if you have no good answers, I would change everything right now !! Lol...

If your life depends on it, weekly changes of everything might not be enough.
Somewhere along the way, one has to strike a balance. Nobody can tell me where my comfort balance zone is, and I can't tell anyone else either.
