Setup: '68 Mercruiser Pre-Alpha (SN 2361794) and 120 Chev 153 (SN 2420015)<br /><br />Discovered water and exhaust leaking from exhaust bellows (PN 45597A 1) and suspect that water in bilge caused by this. The new water shutter and mounting flange are in hand. Can someone tell me how this flange and shutter is mounted inside the bellows where the bellows meet the lower pipe? Repair manual silent on this subject. Can get to the 4 hose clamps easily, but from that point on I'm lost.<br /><br />Thanks in advance,<br /><br />Swabbie
