I have a 1999 Larson SEI 186 with a 4.3gl and an sx-m sterndrive. I have some damage to my lower unit, and am in the process of removing the outrdrive. I am also preparing to winterize my boat for the first time by myself and am curious how I can give the system water with the outdrive removed? I have read some different things, but curious if anybody knows for this particular engine what would work?

You have to feed water to the impeller housing; there are a few ways to do that; one is to fab up a fitting for the garden hose and then have someone hold it into the water passage hole in the pivot housing and stick a rag in the bellows to keep water from the exhaust housing from spraying into the driveshaft bellows. The other way would be to make up a hose adapter to connect the garden hose to impeller housing itself, that is probably the better way.

On Volvos, I hook the hose direct on the raw water pump with a rig I made

However in the SX you can also connect to the hose between the outdrive and transom shield

Do you happen to have a picture of how you connect the hose directly to the water pump on a volvo?

I am going to try to take the drive off today or tomorrow and will probably ask you if you don't mind, to confirm I would be putting water in the correct spot?

Nothing special. It's a female hose fitting to 3/4" hose, a plastic adapter that connects 3/4 hose to 1-1/4" hose and it is connected to the inlet side of the raw water pump.
