The main problem with the 42 tiger and big blower motors is the fact that the motors are moved forward because of the transmissions in the 6s. Thereís too much weight moved over the steps. They had a 42 w/ 6s and it purposed so bad it was dangerous. They put 1000lbs of weight in the boat forward to get rid of the problem, it worked for the most part but it wasnít impractical to carry 1k of lead weight. The 42 is a BRAVO only boat, not to say it couldnít theoretically work with 3-As w/ the tranny in the boxes. Who knows. But essentially itís built for bravos.
