It seem it have antifreeze in the engine . Don't know much about boats. Is that normal looks like there is a coolant tank to. The only other boat I had was a merc 120 and it wasn't like this? Plus the starter just went out any ideas about what to do to prepare for winter? Thanks ben
 
Ayuh,... If the antifreeze is strong enough, No problem there,... Just bein' green ain't good enough, Test it...

The raw water side of things still need Draining though...
 
one side of the heat exchanger is A/F, the other side is seawater/lakewater and needs to be drained. some remove the endcaps to drain, some remove the drain plug on the bottom ,the rearmost one.
