Hey all - Posting a question here with regard to a YSM12 Yanmar fitted into a '78 Catalina 30. The exhaust system on my boat was installed by the PO and is an aftermarket manifold lift w/ mixing elbow that was custom manufactured. It basically comes off the engine on the aft-starboard side - crosses aft and lifts across to the port side to then mix and dump into the water-lift located on the starboard side of the engine. Its a water-jacketed lift manifold and mixes cooling water and exhaust as it dumps into the water-lift.
The system is nice and worked well but failed 2x on me right where the manifold bolts to the engine. I had it welded but I am afraid its beyond repair. The inner exhaust pipe is failing and is covered by the jacket so its difficult to weld.
So Yanmar does make a YSM mixing elbow that lifts and mixes cooling water with exhaust gas. My question is as follows: Does the Yanmar issued-mixing elbow fit into the C-30 engine compartment? I see from diagrams I am able to find online that it does rise above the upper-most portion of the motor but I cant get any dimensions on how high. All the parts I need are supplied by Torrsens and comes in at around $300.
Thanks and appreciate any insight.
