I have a 1985 19' Cougar tunnel with the 200 Black Max. It is factory stock, except for a 24 pitch 3 blade. Factory broucher said it came with a 26 pitch. The OB is mounted on a 4" rigid, angled setback bracket. What engine mods would unleash more power? Would a jack plate do anything for this setup? I was told this engine has a great power to weight ratio, is this corect? Any info would be great. Thanks for the help.
