" Okay I have a stumper. The engines are 350cu.in. Chris Crafts with flywheel forward. Twin engine set up in a 1961 Chris Craft Roamer,problem is with engine running hot at 2800rpm and higher. Both engines are new blocks (1yr. old) and are freshwater cooled using Econo heat exchangers.
left engine runs great,temp. normal, right engine overheats and builds up pressure but not from steam. If the engine is ran on a cruise and then sits for 2-3 days it will blow air from the fill cap when removed. This is using the original cooling circuit common on these engines from this era,ie; positive flow pump mounted on the back of the generator (twin vane pump),no thermostat and no engine mounted water pump. There are no blockages in cooling system and impellers are good. Any ideas or original drawings on this engine cooling system ? "
