Get a 1/4 in. aluminum plate long enough to put 2 bolts behind the 2 you can get in ,let the plate extend out to bolt 2 more of the motor to. You will end up with 4 bolts in the boat and 4 in the motor the back 2 bolts will be just through the plate and boat the next 2 will go through the motor plate and boat, the very front 2 will be through the motor and plate.
