Probably wont mount thru the hull, as you need a flat surface to mount to. Surface mount is usually only done on flats boats. You will need to get one of the mounting plates from Power Pole. Not sure which one, as the sticker on mine has disintegrated and I cant read the model number. The mounting plate goes between the outboard and the jack plate – unless you have a Bobs jack plate, in which case the mounting plate will have to go between the transom and the engine. The guys in Tech Support at PowerPole can get you hooked up with the correct plate. Let them know which jack plate, engine, and hull you have.
