I need to replace my tilt and trim senders on my 1992 alpha one outdrive. There was nothing wrong with the wires but water got inside the sender rusting the reostat. I know that I will need to pull the outdrive to properly replace the two switches but is there another way. What is the reason why I cannot just cut the existing wires and then splice and seal with silicon to prevent water from contactin the wires.<br /><br />Thanks in advance,
