Yanmar cooling confusion
I'm getting familiar with my I-30 that has a Yanmar 2GME engine. My previous boat had an Atomic 4. Based on the surveyor's report, the engine is fresh water cooled. However, he also notes that one of the thru hulls has an "internal strainer for engine raw water". I'm confused. I didn't see a water muffler so I'm assuming that it is indeed fresh water cooled. Any thoughts?
