OMC Cobra 5.7 with closed cooling no impeller?!?!

[Spivy30]

Recently purchased a 1986 Starfire Westport 265 from a charity off eBay and am having trouble figuring out the closed cooling system. The boat originally came from Long Island and somewhere along the line closed cooling was added for running in saltwater. My problem is that when the boat was last winterized hoses were disconnected and I can't figure anything out. First off the water inlet from the transom has been capped off and a sea strainer has been added just ahead of the engine which would make the factory impeller in the sterndrive inop. At first glance I assumed the boat would then have a engine mounted impeller run off the crank similar to an inboard but I can't find one and it doesn't look like there was ever one there. So my question is how does this work and how do I hook it up again? I also noticed that there are some hoses coming from the power steering cooler that go to nothing?

I will attach some picture of what I have.

I'm thinking it my be easier just to buy an original t-stat housing and convert it back to raw water cooling since I'm on Lake Michigan but I like the idea always having antifreeze in the block and simpler winterizing.

Is there a raw water pump directly mounted on the crank pulley?

No but after doing some searching I found three bolts that were threaded into the harmonic balancer so I'm guessing the impeller was mounted there and was removed to be replaced and never installed. I found a used Volvo front mount water pump that I am going to adapt.

My next question is where would the hoses from the power steering cooler go?

Pics of the pump and hoses?
