I gave up on boatdiesel a number of years ago following Tony Athens’ falling out. I wrote several articles for boatdiesel during that period and one article referenced Sbmar as a source of specific information on servicing aftercoolers.
The owner of boatdiesel, can’t remember his name, wouldn’t publish my article unless I removed the reference to Tony Athens’ Sbmar.
I refused and gave up on boatdiesel after that. Good riddance.
It is sad, because at one time it was the go to source for marine diesel info. Now Sbmar’s forum covers Cummins engines thoroughly and it now looks like their forum doesn’t cover other makes.
So, I don’t know where to go for current advice on Yanmar’s, Volvos, Cats, etc.
