Turn the water faucett on completely open, not 1/2 way. I don't know why
anyone would want to run the risk of overheating an engine by turning
it on 1/2 way.

Note that you will be putting pressurized water in to the impeller with
the hose adapter. That may mask a problem with the impeller. Using
a barrell isn't a good idea with a 115 HP engine. It will heat up
quickly.

Keep an eye on the temperature gauge as you have been doing.
