Hello, can you tell me what transmission you have? I just bought an SB12 with the same gear and am trying to figure out what it is. Thanks,

[@sailingthanksdad]

To the best of my understanding, there is one transmission for the SB12. My info here: sailingthanksdad.com/index.php/yanmar-sb12-documentation/

Great stuff! Have you ever changed the rings on this motor? Am wondering if thats a big job or not on this diesel motor?

[@sailingthanksdad]

Hi Nathan, no I have not had the "pleasure" yet to change the rings.

@@sailingthanksdad Well, when you do be sure to video it! =) I'll be the first to like, and try the same kind of job! Thanks for your great vids btw, I have learned a lot! :D

How heavy is your boat and lenth ? I'm building a 22' pocket cruiser and looking for a engine that's economical and dependable and that I can cruise at 6 or 7 knows. Nice video thanks

[@sailingthanksdad]

The spec’d displacement is 8,500 pounds.

I have one of these engines. It is raw water cooled. Do you have a heat exchanger? Not enough water is being expelled with exhaust. Have you worked on the mixing elbow etc.?

[@NalbachEngineering]

No, we do not have a heat exchanger. Mine is raw water cooled as well. My mixing elbow rusted out a few years ago and I had to replace it. Here is a link to my project: thanks-dad.blogspot.com/2013/06/first-sail-of-season-and-few-more.html
