We sail a 2003 H356 and I recently had the new owner or our marina boatyard replace the impeller in the 3GM 27hp Yanmar engine. The impeller had been replaced several years before by the former owner. The new owner informed me that we had the European version of this engine which had a different water pump than the Japanese version and, hence, require a slightly different impeller.
While I could have handled the replacement myself, I considered this job an excellent, low-risk way to get to know the new manager and get a sense of his business style and expertise.
In all the years I have owned this boat and read this forum, I have never seen or heard anything about two versions of this engine. The previous boatyard owner never mentioned it. Can anyone verify what I was told? If there are different versions, are there any other parts or assemblies that differ based on this version?
Thank you.
