I have a Volvo 100hp TMB31B about 10year old.Can anyone say exactly where the engine block anode is as I can not find it and expect it needs replacement.
Look for a 1/2" square blob sticking out of the side (or more than one) as these may well have pencil anodes on them. That's extrapolating from a 41 anyway. Look at heat exchanger, oil cooler and similar as well.
Ok got the part from the mechanic to do the job_he is back in Spain so no help-so I know what it looks like-but still can not see the spot.seen them on other engines as well but not on the 31B or 31A.
