I have searched the forums and performed every test that I could. I am at a loss here. To start with, the boat wasn't winterized as good as I thought. Ended up having to replace two freeze plugs in the engine and the power steering cooler. Here are where my issues start. Before I knew about the PS cooler issue, I ran the boat on muffs. I was getting PLENTY of water coming to the PS cooler....because it sprayed all over my engine compartment. Replaced the PS cooler....and now I have NO water flow to the engine. I have removed the hoses to verify blockages...none. I have removed the drive and the hose at the thermo housing. Then I flushed it by holding a hose to the stern drive...forcing water up through the PS cooler and up to the disconnected hose running into a bucket. The water flows fine...no blockages. With the drive off, I inspected the water pump housing and impellor. They are fine. I replaced the gaskets and alignment piece for the water pickup tube between the upper and lower halves. I ran water through the muffs, and had the water pump disconnected to see if water was able to get to the pump. It flowed fine. So I have verified that there are no blockages of any sort, but it still will not flow any water! It worked up until I replaced the PS cooler! Any thought of what to check next? Could bad seals in the lower drive be to blame?
