5 Gallon Bucket
Here's a shot of my "t" fitting between the through hull raw water intake and the pump. To run the engine while the boat is out of the water, run a (short) hose with a shut off at the end from this hose hose fitting and into a 5 gallon bucket. A simple plastic garden hose shut off works. Then run a second hose from the hot water discharge at the aft end of the exhaust manifold back to the bucket. Now you have a closed loop. Close the through hull fitting open the ball valve seen here and the shut off at the end of the hose and let the engine draw from the bucket but only AFTER she turns over and catches so you don't flood the engine. You can run the engine for a while and not have to worry about spraying hot water out the back. By the way ,that's the copper jacketed exhaust running behind the fitting. A side benefit of this method is that you may get to see any crud that's in the system and it'll have a chance to settle out in the bucket.
