I'm wondering if the rotor wasn't screwed down all the way or sitting level. Or if the constant bouncing on the water was making the cap bounce around. I put the old rotor back on and no signs of that so far, but I've only run the boat on the river which is nice and smooth. I plan on getting a cap that screws down to the distirbutor instead of using the stock style spring loaded setup. A car doesn't bounce around like a boat does so I could see that being an issue on a longer run like I did.
