1979 searay mercruiser sterndrive ser # 5198280 my tilt and trim lines are leaking into the boat. i can not see the connection as it is under the drive shaft on the transom. the lines are dry as far as i can see down. what is the easiest way to get at the lines . on the outside i can see where the 4 trim tilt lines connect to a plate that is screwed to the bottom of the motor. im wondering if i can pry off that plate which is held on by 2 nuts and access that part of the interior lines to replace? sorry if this sounds confusing but any advice or help would be appreciated.
