I have several Pacific Pumps, both model N and NH. They were built in 1939 and 1941. The 41 unit was accepted by the USN. Both have upright 2 cylinder engines, one built by Evenrude, the other by Johnson. Both have the same specs - 9.9HP@6800RPM. 150PSI output, capable of 15 feet of lift. They both use a bronze gear driven screw type pump. Both also have foam eductors for using foam to fight gasoline fires. They will pump in the area of 50 to 70 GPM with a 3/4 smoothbore nozzle. Both engines are fitted with an exhaust dump valve, which bypasses the muffler and scavenger system. Supposedly, it ads 10% to engine power and pump output. I only tried it once. The engine did seem a bit more powerful, but the now open exhaust sure was LOUD! Both units use 2" hard suction intake and 11/2" discharge. For onboard use, soft 111/2" hose was also hooked to the exhaust port on the pumper base, so as exhaust fumes and pump cooling water could be discharged outside the compartment. early pumps had a valve on the engine water supply, so as to regulate engine cooling. Later NH units did not have this valve. Water was passed thru the cooling jacket, then into the muffler where the relatively cool water helped the engine scavenge the fuel/air into the cylinders. fuel/oil ratio is 8:1 (1 pint SAE 40 oil to 1 gallon gas, for first 5 hours (break in), then 12:1 (11/2 cups SAE 40 oil to 1 gallon gas) for running normally. On my units, point gap .018", plug gap .025 NEVER run these engines without water! Fuel consumptioin about 1 to 11/2 gallons / hour!

Pacific was in operation for many years. It was bought out, and all support for existing units has been dropped. I have not been able to find a parts source for these unique pumps. I do have a manual for I believe the NH, I will try and dig it out at a later date. In the meantime, if you have operating questions, don't hesitate to ask!
Andrew

Hi ray.the engine is a Johnson outboard powerhead.k-50,k-65,k-70,k75,k80,kd-15 and ks-15 model Johnson outbords take the same piston and rings.the ignition is same as models I listed.I have few rings that u can put one on each piston to increase the compression.
