Looking for advice with my 2005 mercury 25 hp outboard
Alright so I have recently obtained a 2005 25 hp mercury outboard. It was used in saltwater and not flushed before years of storage, almost everything with it is decent except on the lower unit. On the top of the lower unit there is a golden sleeve that holds two seals, and it is badly corroded. I’ve included an image of what sleeve I’m talking about from online cause I don’t have a photo of mine. I’ve found the sleeve for sell as a part online, but I don’t know how to remove it from my lower unit. I’ve done research and have only found one other person asking how to do it in the past with very little information on it. The manual online says not to remove the sleeve for basic maintenance, but this is different. Has anyone dealt with this before? Thanks
