[C320-list] Blacck Soot in engine compartment

[joe at dolphinmortgage.com]

I found the source Yesterday and it was the exhaust elbow. Chocked full of black carbon. The elbow looked like hard metal but here it joined the manifold it felt like pudding. I did replace the hose leading from it to the muffler as we wrecked it getting it off the elbow but for $15 at WM worth it for a new one. Question, where is the cheapest place to get a new elbow for the Yanmar 3GM30F? We have a local Marina that is a Yanmar dealer but they are probably expensive. It was not stainless and had no heatshield wrapping so I think it's a Yanmar part. Any ideas on where I can get a good price?

Subject: [C320-list] Engine alignment

Thanks Larry. If the shaft is not centered in the log, is there anything that I can do about this? It seems to me that the two bearings on the shaft are not adjustable without some serious fiberglass work. Slotting the engine mounts a little more is probably worth a try as I probably only need a little more room at the front of the engine. Thanks again Chuck Northwind #676 -----Original Message----- Chuck, I haven't experienced the problem you are having but have done enough alignments to know exactly what you are talking about. Be sure to check that the shaft is centered in the stern tube (shaft log). With the coupling disconnected and separated about 1/4 -1/2 inch you can move the shaft athwartships until it hits the sides of the log and tell if it is centered. It may be that you are trying to align the engine to a shaft that is not positioned correctly. If this is not the problem another option would be to extend the slots on the slotted plate if there is room rather than try to move the hole over a little in the engine beds.

The slots in the front motor mounts are bottomed out and there is still a lot of horizontal misalignment. And I can't move the rear motor mounts to starboard and still get the shaft to align. Has anyone else experienced this? It seems like the shaft is angled to port. If I drill new holes for the motor mounts, is there a backer underneath the fiberglass that I can tap into? Thanks for any suggestions Chuck Mueller Northwind #676
