Hey folks. Ok, maybe a dumb question, but how do you level the transducer horizontally, i.e. starboard to port (not vertically, I get how to do that) so it is perfectly parallel with the bottom. Obviously, I’m doing the install on dry land with boat on trailer. I know the driveway is not level. And even it was, I can’t assume the boat is perfectly level sitting on the trailer. I decide to use a spirit and wheel jack to get the boat level. But what surfaces can I assume are level on the boat. Not sure the transom is level or the carpeted floor. Do I just lay a spirit level from starboard beam to port and assume that is a level surface? Man It seems whenever I undertake a DIY, seemingly simple steps become overwhelmingly complicated. But I’m determined to get this done.

Great info. Thanks guys.

Hey folks. I am doing my first transducer install on my 4.5m Aluminium Brooker runabout and need a little advice please. I’m aware I need to choose a flat, unobstructed point on the transom to mount. Avoiding chines, welds and hardware etc, to ensure unobstructed water across the transducer. The concern is that the weld along the bottom of the transom creates a small ridge. So, running along the hull it is smooth until it meets the transom. There, the water would have to travel over the small ridge created by the weld. The manual for the unit recommends mounting 10mm below bottom of hull. Is this going to create a disturbance in the operation or the transducer. Of course, there is no way to avoid it as the weld runs the entire length along the base of the transom. Should I attempt to file / sand this weld line flat or could this jeopardize the integrity of the weld? Thanks
