I'm looking at a 1990 Sea Ray "Laguna 23" with the original twin Mariner 135s. I have asked several local techs, and get different feedback from each regarding reliability and life expectancy. <br /><br />Both motors are showing 600-700 hours, and they have been regularly mantained, but not rebuilt.<br />The owner said the #s from a compression check are noted under each engine cover, but I don't have the specifics yet. He did say the power packs, voltage regulators, water pumps, and thermostats, have all be replaced in the last 3 years<br /><br />Does anyone have personal experience with these outboards?<br /><br />Any feedback would be greatly appreciated.<br /><br />Thank you,<br />TS
