I have some PVC pipes, rubber hoses, and copper pipes need to pass thought water-tight bulkhead of a composite ship. But I do not know how the passage should be to ensure that bulkhead is still water-tight one.
Could any one have experience about this, please help me?
Thank you very much,
We are design a Catamran boat (8m length, composite). And I am going to use 2 Parsun outboard engines, 30hp/1 engine (remote one). But my problem is: I do not know how to combine 2 engines together. Do I need a hydraulic steering for them. Or just leave them saparating like that and connect them...
