well I'm not trying to start another "Mono v Multi" or "who's smarter left or right handlers". But I am interested in what other engines You guys have had experience with. I have had experience with only 5 different brands.
1. Detroit Diesels (GM)
2. Perkins
3. Cummins
4. Cat
5. Gardner
i have heard good things about Yanmars as well.

Would love to know the most amount of hours you have seen on engines or outboards.

Just interested.
Regards,
Mick
