I recently bought a 28' Cape Islander wooden boat with a 4.3 mercruiser engine and an alpha 1 stern drive. The oil in power trim motor looks as though it has water in it. I emptied the resevoir and replaced the oil but when I trimmed the drive up and down a couple of times the oil looked like it was still contaminated. Does anyone know how to get all of the old oil out of the system>
Thank you
