1980 Silverton 34C with Chrysler 360s on V-drives. Silverton built these boats with four exhaust outlets through the transom: one for each bank of cylinders on each engine. Each one has a muffler and the hose size on each of 3-inch ID.
What are the consequences of blocking off the inside two holes through the transom and combining the exhausts into one 3-inch muffler and outlet on each engine? Why? The extra exhaust hose and muffler take up a lot of valuable room behind each engine that I could use.
I helped a dockmate replace his exhaust system on a Bayliner 32 last summer and his two 5.0 liter Mercruisers have their exhausts plumbed together as I am proposing.
Later Silvertons had only two exhaust outlets and I don't think any decrease on horsepower is going to be something that an old and fairly slow cruiser like me has to worry about.
Maybe a slight increase in exhaust noise? 2X the cooling water flow through the single muffler, though.
Any reason why a Chrysler 360 can't exhaust through a single 3-inch wet exhaust system?
I'm not doing any modifications until I hear from you guys.
