It replaces Volvo Penta 876376 and 875553 and corresponds to Orbitrade 21553 and Crom Marine 121049, and it is one complete set in a 22 x 30 x 1 cm pack.\u003c\/p\u003e\n\n\u003cp\u003eThe MD11 was built in large numbers for sailboat auxiliaries, and the reason the head comes off is almost always the same: hard starting, white smoke and water or compression loss at 0.9 litre displacement, usually after years of short runs and raw water cooling. Doing that job with individual gaskets ordered one at a time costs more in freight than the set costs in full.\u003c\/p\u003e\n\n\u003cp\u003eThe kit is the decarbonizing set, so it covers the head gasket, the manifold and water joint gaskets, the rocker cover gasket and the seals around the raw water pump drive. Anything the job needs to go back together sealed is in the pack; the head bolts and the thermostat are not.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable
