It is a direct replacement for MerCruiser 87-864252A01, 864252 and 805024, and cross-references 87-8M0070108. This is the newer style with the harness adapter and supersedes the older switch. The switch cuts the fuel pump when oil pressure drops, so a failed one either kills the engine at idle or lets it run with no oil pressure and no warning at all — which is why it is worth renewing before it strands you.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications \u0026amp;
