Pacific Marine Pump

This 1930s Pacific Marine pump is powered by two Johnson outboard engines paired together to create a four-cylinder power plant for running a pump.

Contributor Herb Higginbottom sends in some interesting pictures this month of an engine and pump rig built sometime in the 1930s by the Fire Equipment Division of Pacific Marine Supply Co., Seattle, Wash.

This four-cylinder engine is apparently built up from two Johnson outboard, water-cooled, opposed two-cylinder engines.

'The water jacket on one-cylinder was broken,' Herb says, 'so I welded on a new piece. Two pistons were stuck. I broke them loose by filling the cylinders with oil and fitting an adapter in the spark plug hole. Then I used a grease gun to break them loose. We were lucky this time, as the pistons were above the exhaust ports.'
