Volvo penta in fairline mirage 29

[kevinjrob]

Hi all. New to boating but very handy with spanners. Just bought an old 1980 fairline mirage 29 with twin petrol engines. Have been told (and confirmed by sticker on volve cover) that they are penta aq130c's. Need to remove a head so bought a head gasket kit and now confused. The kit (and all the images I have found) show the exhaust and intake on one gasket, but mine is a crossflow design. As looking from the pulley end twin downdraught (solex 44pa1) on the left and log style exhaust on right. Raw seawater cooled with pump driven off the end of the cam. Definitely push rod ohv petrol. What is this likely to be please?

Kind regards

Try posting this in the Thames Forum here. You may get more replies for that type of boat / engine set up.

The AQ 145a and 140 was also used in the mirage.

We sold quite alot of Mirages around that time. the earlier boats had the 130s then 120s and 140s quickly followed by the 125 and 145. The 130 was the only 4 cylinder pushrod engine.
I seem to recall some of the mk1s with a single straight 6 170 pushrod engine.

Is this not the same as the Volvo 1800cc B20 engine as used in cars but with a marine head gasket ? If so the exhaust and intake appear to be on one side of the cylinder head ?
