Sure did. Tried with just the power and the black one going to the starter and reversed them. Starter motor ran both times as soon as I touched the cable to the terminal. It could also be the relay, not sure. Anyways, I'm looking at buying this:

It might not be the best out there but $51 compared to the Volvo Penta one, $399, it's worth a shot. Even if it only lasts a couple of seasons.
