Hello
I'm rebuilding a dory with a 4hp Acadia. What was the original colour for this engine? Mine is sort of a metalic green.
Also, the original installation for the exhaust used 2" pipe into a cast iron muffler and then continued the 2" piping and exited the exhaust out the side of the dory. Is this size piping to large?
Does anyone place any material such as rubber between the engine and bed for vibration?

Well if Stan is correct it never would have been green in the Maritimes. Many were slapped with a coat of red lead as soon as installed because red lead turns color when it gets hot. I received the last two cylinder Arcadia exhaust manifold from them 20 years ago and it was painted a blue silver color. Don't know if that was a primer or the proper color. Prudent engineering places a six to eight inch long section of steam hose between the engine cylinder and the pipe to the muffler. A prudent design would inject jacket cooling water into the exhaust close to the cylinder aimed down stream to keep the steam hose from burning up. The weight of the muffler to be isolated from the engine and arranged so jacket water is vented through the pipe to the side of the boat. Many watermen never had the luxury of a muffler hence many were deaf in their old age. Up to your call! |

General practice for the single cylinder engines is to bolt it as tight as you can to the bed. They are essentially unbalanced things and will vibrate the heck out of hull and eventually loosen the hull fastenings - then your boat becomes a leaker. Big heavy engine beds are good.
Have a look at my post under Boats with Old Engines - July 22 - you'll see a good neat instlaation of a one clinder engines.
