help finding drain plugs

[jhyde]

I recently purchased a 2010 with a 5.7 with a bravo III outdrive, I can only find two drain plugs to winterize the motor, one on top near thermostat, and the second in the front right  side at the very bottom.  I see a couple hoses coming from the manifolds that drain to the same bottom plug, should there be more?  Also I don’t have any Greece fittings on the outdrive ? My old boat had 3 , how do I Greece the outdrive ?

Get a bail out from the rest of the world?   

All kidding aside, there should be one port side underneath the riser.  and the hoses are also used to drain.  My fitting (1) is on the side covered with a little plastic cover.  Careful not to over grease that one.

On your 2010 model Bravo Mercruiser you will have 4 plugs.  One on the Thermostat, one on the low point drain, and two on the sea water pump.  All are blue plastic plugs.  The sea water pump is the hardest.  I drain the low point and vent the thermostat.  And run Marine antifreeze through the outdrive and into and out of the sea water pump.  When a steady stream of pink Marine antifreeze flows out the low point drian, you are protected.   Good luck  Al

Al;  Do you run the engine while doing this, or do you use a pump to push the antifreeze thru the engine?  The plugs on the sea water pump are a _itch to get to

I run the engine and use a bilge pump connected to the muffs to pump the anti-freeze through my boat. I am sure the gravity method works, but I like using the pump.

I utilize a 5 gallon platic container with a valve and hose assy connected to a Flushet attachment.  I basically use gravity to  flow the Marine antifreeze to the drive and let the pump suck it in.  And yes I start and run the engine to flush the Marine antifreeze.  Al
