Considering a new engine for your Contessa 26? Or are you planning to repower another boat? Or do you just like boats and machinery? If so, you came to the right place. During the Fall of 2000 and Spring of 2001 I replaced my Farymann K30M with a Yanmar 1GM10. I took pictures along the way. In these pages I will show you how I did it, and tell you about the decisions made and the lessons learned. This is not a how-to manual, but you may get some ideas for your engine installation, or learn something about the pitfalls of such a project.
