I'm installing a humminbird PiranhaMAX 150 depth finder. The transducer installation on the transom calls for at least 15 inches from the motor so it won't cause interference with the depth finder. Well that puts me directly center of my trailer runners when loading the boat. My question is can I mount it 13in and be free of interference? I have a 25hp Yamaha so won't be doing top notch speeds
