Picked up a 1999 SX 175 before the season began for the kids to have some fun on. (They don't like sailing because "it's boring daddy".) Anyway, we've had the boat out quite a few times & they're are really enjoying it. Now they want to go trout fishing this weekend, which brings me to my stupid questions. First, the jump seats in the rear, how do you pull them out to use them on the fishing platform? (Haven't been able to figure this out.) Second, the factory installed fish finder was removed so for fathers day the wife purchased me a new Hummingbird that I now have to mount. I plan on using the original wiring as the snake for the new but I don't see any transducer on the hull/transom or any evidence one existed. Was the original transducer mounted inside the hull or something? In other words, don't bother even using the existing transducer wire as the snake for the new one. Should I simply just go with the transom mount option for the new one? Thanks for dealing with the "newbie" questions.
