So I usually stick the engine in a tub of fresh water to run the salt out of it, but I was looking at using a hose on the inlet port instead.
Does anyone here do it that way? The manual says to stick gaffer tape on the water grill under the plate. Wow that's hi tech.
Looking at the flush point screw its around 10mm but Not quite M10 thread, i'm almost tempted to retap it M10 and make a stainless adaptor to garden hose and replace the screw with a short M10 allen head bolt and washer if its going to keep getting removed to flush it.
I think this is what Suzuki sell for the port
