:These H&P motor mounts will work with standard Zenoah cases or with the Gizmo billet cases. They allow you to cant the motor over up to five degrees to get the exhaust header lower and the carburetor higher. They are designed to be used in a boat with a 3/4” deep belly pan to get the motor as low as possible. They mount through the bottom of the boat eliminating the need for rails. They could be used in a boat without a belly pan by making taller angle brackets or by putting spacers between the isolators and the floor of the boat. Picture shown in 8255 1/6 Scale. Motor and boat not included.
