SNYGG is one of the first motorized fishing boats on the west coast, registered with an "H" number in the fishing registry. Built around 1880 and motorized from 1924. Same motor in her today.
She was in very rough shape when we found her. Me and one other guy in our local Coastal Federation used more than a year making repairs while a motorman in the club fixed the engine - a 4.5 hp 2 cycle hotbulb semidiesel.
This year a regular spring workover was all she needed. And she is a real looker.
SNYGG was originally an Oselvar seksæring, the next size up from an Oselvar færing. An Oselvar 'six-oaring' is about 24 ft. They added a strake and bigger frames when the motor went in.
The Rap hotbulb semidiesel has a spreader instead of an injector and slightly lower compression than a more modern semidiesel, like a Sabb 8-10. The spreader is pushed into a hole in the top of the cylinder, held in place with two thumbscrews and turns 180 degrees to dowse the hot bulb en the top where a sparkplug sits in a petrol engine. To start, you warm the top of the bulb with a blowtorch for 15 minutes, open the regulator a touch, turn the oil box over twice and kick the flywheel backwards using a spring loaded pin in the front of the flywheel. If rhe bulb is hot enough, the engine fires when the piston compresses the mix going backwards and kicks the flywheel around forward. After start, you turn the spreader so it sprays down into the cylinder. There is also a water valve that can be used to boost the compression when more speed is needed. It pumps a small dash of water into the cylinder when its running fast, if you dare.Its an easy start when its hot. When its not, it can start backwards.
Once running, the injector pump, water pump and oiler run off an exterior eccentric axle at about 50 rpm at idle and maybe 200 at full throttle.
The propeller reverses the angle of the blades with the wheel you can see sticking up behind the motor housing.
The guys launched her today while I was out of town. Seems it went well without me.![]()
