No. The transom is the strongest structure of the boat; This is where not only the motor but also the TurboSwing will be mounted. The TurboSwing holders fit exactly on the motor bracket and will be, together with the motor, mounted on the transom using the same bolts. The holders are universal, therefore the holes in the holders match the holes in the motor bracket. All motors from 40HP, with the exception of those from Honda from 175HP and Evinrude from 75HP, have exactly the same brackets. The main bolts at the top of the motor bracket that are already present will be used. For reasons of stabilization, on both sides a 2nd hole will be drilled and a 2nd stabilization bolt installed in one of the 4 or 5 pre-drilled bolt holes. Always leave a minimum of 1, but preferably 2 holes between the main bolt and the stabilization bolt. Otherwise, no drilling or sawing is required at places that are unsuitable and that could weaken the structure of the boat. Reinforcement with epoxy and/or other structural reinforcement is unnecessary.
