I would suggest it is an A as it looks identical to the TMD40A on my last boat. If you want the workshop manual and spares lists please PM me. Not sure what the physical differences were from the A to B to C.
Thanks guys.
can I ask what the difference in the AQAD40 A and the TMD40A is?
Are the both the same engine?
Thanks
Agree not an AQ'A'D - no aftercooler on this engine, the plastic air filter casing attaches directly to the turbo, which blows directly into the long inlet manifold with the nibs feeding to each cylinder along the top of the engine parallel with the rocker cover.It looks to me a AQD40 as no aftercooler is seen, and i'm guessing it is a "A" model because of the 270 drives and the black volvo penta sticker. With aftercooler it is named AQAD40
