i have a smokercraft 14ft big fisherman probably 25yrs old, the outboard is a 25hp manual start Yamaha, i had the boat out a few times and i noticed when i am running the outboard at slower speed maybe 1/3rd throttle everything seems to be ok, when i get up around 3/4 to full throttle i see water gushing up along both sides of the motor on the rear of the transom and seems to come over the transom into the boat, does this have anything to do with motor set up which i never done, to remedy this seems like i have to make some kind of plastic or aluminum deflectors on the transom, would one of those fins attached to the motor help, is this a common issue, i have had 3 or 4 boats over the years and never saw it happen.
