- Greetings all,
My engine is sounding a bit louder these days. Raw water flow is normal. Has anyone replaced a muffler on a J/42? What muffler/configuration makes sense?
The original is a Marine Muffler, Inc., Primex Silencer, Part No. BC 030-0001, a 7" diameter cylinder about 22" long with a flapper valve at the inlet end. They are now out of business.
Hull no. 74
