Flushing cooling system on a 1985 Dorel 27' inboard/outboard. I have placed muff on intake of outboard, have lots of water flow from hose but no water in engine (with engine running). Any ideas?
Your engine are probably V/8s and have a water intake through the bottom of the hull and belt driven w/pumps on the front of the engine. You will have quicker anwsers on the I/O forum in the future
