I am in the process of upgrading my boat to a two battery system and am also upgrading my alternator to a 140 amp marine alternator from DB Electrical. I was ready to order when I noticed it is a clockwise rotation. Is that the correct rotation for a 1984 PCM 351w engine? I have been running the stock motorola 37 amp. I am now second guessing myself. Can anyone set me straight so I can order it?

thanks
Dan
