I'm looking for a manual for a Yanmar 2 gm 13 RWC. Can anyone advise? Thanks
Otherwise I have a ratty photocopy on my boat or you can buy one online at Torrensen Marine. They are a good source for parts as well. They are very knowledgeable and have excellent customer service in my experience.
Here's a link to a 2GM20 manual website. Your 13 might be real close.
