Mercruiser 454 block drain plug locations. My boat is a 454 mag and i know i have 5 plugs 3 port side 2 starboard side. Drain exhaust manifolds by pulling 2 hoses 3. Fill block with antifreeze through big hose to recirc pump. Start from the highest drain and work down so you have water pouring out of all of them as you clean them.

Yes the drain plugs being fouled with crud and scale is common. On my friends boat i could only see 4 2 port 2 starboard elbow fitting and engine block pe side. Does anyone know how many drain plugs there are for the 7 4 lx.

The plug i took out does not appear to be brass. When placing one of the engine block drain plugs back in after draining it would not tighten up and it appears that the threads in the block have corroded and pretty much degraded. Takes 3 gallons fill both hoses to exhaust manifolds takes about 1 gallon. There s also a drain on the cool fuel system port side down around the bottom of the block towards the stern.

In the future keep a 4 6 and 8 nail handy and thouroughly have at it with the scale as the water is pouring out of the drain. Drain block with 2 plugs 2. Two on the block port and starboard sides.
