Does anyone have a prepurchase run though of what engine/outdrive problems to look for when buying as used boat. <br /><br />Looking for information on how to inspect the bellows, gimbal, and the like.<br /><br />I intend to but the muffs on and check compression and for water in the right and wrong places.<br /><br />I am looking to buy an 1989 Sea Ray 180 with the 3.0 Mercusier Alpha One Outdrive. <br /><br />Thanks for your help.
