K, so I'm working on a stern-drive boat made by a company called BlueWater. It's a 69 and has a Mercruiser 120 engine. It's been sitting for almost 20 years. Yesterday I changed the oil and rigged the fuel system with a temporary tank. It started but we soon realized that there wasn't any water flowing through the engine. We had muffs hooked up to the outdrive but there was no water coming out with the exhaust. We took off the largest hose that goes to the water pump and it was dry and full of rust.
The question is: What should I do?
Should I just clean out the system hoping to find blockage that is causing this or should I replace the water-pump on the front of the engine, or something else? I've heard that in some outdrives there's an impeller that works in tandem with the water pump. Do I need to tear into the outdrive and replace that impeller?
