"Anemic Four"
The 'Anemic four' nickname, in common usage, is a bit of a misnomer in my view, and started by folks who did little or no maintenence on the engine.For a rough & tough, can take it all, 30 h.p. maranized engine, you can hardly beat it with a stick.Do not have to bleed injectors, raw water cooled, easily repaired, lots of room to work, and if maintained will always start right up.Flash point of gasoline is low, hence A-1 USCG approved hose is required by law, fixed fire extinguisher system highly recommended, blowers MUST be used.These engines were designed to be run at high, above 2,000, RPM's and can be flushed out on occasion by a 10 to 1 ration of white vinegar to relieve the salt crystals inside the water jackets.Many over thirty years old still giving good service...;-)
