The newer inboards and v-drives use standard rotation engines with a reversing transmission on one side. Other than Marine Power in Louisiana, I don't know of anybody building a new opposite rotation engine these days.

Then your fireing order will be different on the left hand. On the Thunderbolt dist. cap is set up for both firing orders if you have the older style mercurisers.

So remember; Just when you think you have everything figured out, somebody does something like that to you. Merry Christmas! --- Jer
