Re: Winterizing
Dave, It is necessary to drain the block(two drain plugs), Manifolds and risers. Now replace the drain plugs and fill them with straight antifreeze which contains a rust inhibitor(like the auto stuff). Antifreeze should overflow out of the risers and out the exhaust of the outdrive. Now dump antifreeze down the raw water intake hose until it comes out of the outdrive water intake.<br /><br />You also want to change the oil and filter, gas filter, lower unit oil, lube the universal joints, fog the motor. Do an internet search for "Brown's Marina". He published an excellent description of the process. <br /><br />PS it takes me about 4 hours to do this on my Mercriuser.
