My method, with a much bigger engine than the OP (88 bhp) was to put a large bucket full of water on the cabin floor. I detached the inlet hose from the impeller housing and fitted a temporary hose from it to reach to the bottom of the bucket. As soon as the engine started I turned on a hose to replenish the bucket. I did that after each season to flush salt water from the heat exchanger.

I put a hose up the water intake from outside and hold it in place by pinching it slightly with the seacock. Turn on the tap and water pours out of the gap twixt hose and intake. Chances of water getting past the impeller and flooding the engine are negligible. When I start the engine the water draining down outside stops and it all pours out of the exhaust as it should.
Come layup time I put the inlet hose in a bucket of anti-freeze / corrosion inhibitor mix for the winter.

But how much? "it all pours out of the exhaust as it should"

I suppose it is out of my hands-I'm going to have to live with the design as it is. A mixture of steam/raw water is fine?:unsure:

Out of the water you're not running the engine under load and I wouldn't be revving it much above idle anyway. There's ample water from a hose to keep the impeller from melting and as long as there's water coming out the exhaust, and not just steam, you're not overheating the engine.
