I¡¯ve got an O¡¯Day 30¡¯ with a Thunderstruck 10K motor, 2:1 reduction and 4 AGM batteries. ?I¡¯ve got the original 16¡± pitch 9, 2 blade prop that was powered by a 16HP Universal when the boat was built. I¡¯m convinced there must be something more efficient. I can¡¯t even maintain a course into a 15mph wind. ? I¡¯m with Jeff looking for suggestions
