Hi,

I am winterizing my new boat for the first time. Its a 2007 Crownline Mercruiser 5.0L.

Previous years I had a 5.0L but a 1994. On that motor I had to pull the lines on the manifolds, the block, and lower tube on circ pump, and power steering cooler. 6 spots.

On this boat it has the nice blue plugs. I found 5 right away (two block, two manifolds, and circ pump). The question I have is the power steering plug. On the last boat it was easy to find on the port side under the block/manifold there was a large hose coming from the lower unit. On this boat there is no such hose. I tried tracing hoses from the power steering fluid reservoir but no luck. So now i am thinking either.

A) i don't have a cooler
B) one of the 5 plugs i already pulled drain that section.
C) I'm blind and cant find it.

Suggestions?

Thanks,
Mitchell

okay doing that i found the cooler. It looks like the difference is the inlet hose runs on top of the engine vs under. Also the PS cooler is in the very back of the motor. From what i can tell the high point is on top of the engine so the plug for the lower tube of the circ pump should empty that side. The water on the other side should run through the cooler and out the lower end correct?

even if i wanted to disconnect the PS cooler wow what a PITA there is no way i could get back there!

Hi there, Do you have a Bravo or Alpha stern drive?

Re: Power Steering Drain Plug

Here's what I did with mine - your motor sounds similar.

I have an 05, 5.0MPI with a Bravo 3. It looked like the power steering cooling tube is directly behind the engine, and I had absolutely no access without pulling the motor. Heck, it's even difficult to change the spark plugs. What I did was drained the water, cranked the engine a few times without turning it completely over, to get the access water out, while turning the steering left and right. Also, in my Mercruiser maintenance manual, there is no mention of removing any hoses off of the power steering cooler for winterizing.
