Last year my boating season was cut in half because <br />of a blown piston. Started working on the boat this past weekend and notice the hydraulic pump and the long pin (used to protect the engine from kicking upward when in reverse) were very rusty. 1- best way to remove the rust to bare metal to repaint/treat. 2- what do I apply to the part after the rust is removed 3- does this part usually go bad on an engine thats 19 years old (1985 140 VRO) 4- If this part (pump) goes during the season, do I need to pull the boat out of the water to repair/replace it(dread the idea- since I lost half of last season and don't want a repeat performance) Thank you for your response
