This just came in and looks like some really good basic information on marine exhaust systems for smaller engines like the palmer P-60 and others of similar size.
With comments on using wrought copper by Dick Day.
Subject: Suggested Exhaust System for Palmer P-60 in the Morgan 30. This system would be suitable for other comparable marine engine installations.
Drawing no. 1 of 5. This drawing lays it out systemically in such a simple matter that anyone can use it to adapt Howard’s approach to fit any hull or engine just using a little common sense. The water level note and the way the exhaust is discharged from the riser keeps the likely hood of cooling water being drawn back into the engine during engine shut down is very important
Howard’s design in stainless steel is great. A lot of working watermen are probably more comfortable working with copper pipe and wrought copper pipe fittings. Cast brass pipe fitting for this sort of application are really not suitable structurally. Wrought copper fittings are widely available from plumbing supply houses in sizes that are comparable to Howard’s dimensions. Wrought copper and copper pipe braze very well with so called PHOS COPPER brazing rod and they will easily stand up to salt water and heat. For example to make the muffler simply take a piece of copper pipe the length of the muffler wanted add wrought copper end caps with holes cut in their ends to permit the inner pipe to pass through end to end and simply braze the joints. One can do the same general approach for the riser using wrought copper fittings coming into the bottom of the riser with 90 degree radius bends. Where a 90 degree joint between the muffler and the riser is possible the section of flexible tubing could be eliminated simply joining the water cooled muffler to the riser. For operation in cold climates or for system drainage provision should be made to drain the muffler from the bottom of the muffler and riser section.

Howard has also documented the rudder, c'board, and c'board control cable designs for the Morgan 24 & Morgan 30, these are available on AutoCAD. If anyone wants them contact Howard at the above e-mail address
