I have tried to attach a schematic of my engine so here goes. 3 years ago when I started up in the spring gasket #40 was leaking.I replaced the gasket . The next year gasket leaked again,[ smarter now] I replaced it again but while winterizing in fall I poured rv antifreeze into flushing attachment. This year it leaked again, this is a very hard gasket to get at as it is behind the switch boxes. I checked hose #19 this year and it is full of water, I tried blowing it out but it don't blow so I tried sucking it out but it don't suck. LOL Shouldn't this drain when boat is out of water? Why does it seem dead ended [no flow] ?
