| For '58, a new family of
Mercury Marauder V-8 engines with COOL-POWER
design |
 |
| Top: The
312-horsepower Marauder (standard on Commuter)
Bottom: The 330-horsepower
Marauder (standard on Voyager and Colony Park) |
| 1. New In-block Construction - Combustion
chambers in block instead of cylinder head. Heads are subjected to less
heat. Straight-walled combustion chambers eliminate carbon-forming
pockets, help engine operate at peak economy. |
2. New 3-stage Cooling System - Coolant is
circulated (1) to cylinder heads and intake manifold, (2) to block, (3) to
radiator. This means a fast supply of hot water for cold-weather warm-up,
smoother all-weather performance. |
| 3. New Water-Flow Intake Manifold - intake
manifolds are water-jacketed to maintain better control of intake
temperatures and reduce hot-weather starting problems. This results in
longer engine life, better operating economy. |
4. New Cool-Head Valves - In the Marauder
engines no two exhaust valves (in the red boxes) are next to one another.
They are alternated with the cooler intake valves (in the yellow boxes) to
help eliminate power-robbing hot spots. |

| Mercury's revolutionary Marauder V-8
engines with Cool-Power design score a victory over heat and friction -
deliver a new kind of power and performance never before achieved in any
station wagon. New, from the shape of the combustion chamber down to the
last bolt and gasket, this new team of Mercury Marauder engines
outperforms any other engine on the road. Each station wagon series has an
engine tailored to its specific needs: the 312-horsepower in the Commuter,
330-horsepower in the Voyager and Colony Park. The 360-horsepower Super
Marauder V-8, and for those who demand the ultimate in performance, the
400-horsepower Super Marauder, are optional on all 1958 Mercury models.
Some of the basic concepts which contribute to the new high in efficiency
are new short-stroke, low-friction design; higher ratio of power to engine
weight; 10.5 to 1 compression; 4-barrel Thermo-Matic carburetor;
wedge-shaped, in-block combustion chambers.
These spectacular engineering advances enable new Marauder V-8 engines
to step up cooling efficiency, score an important triumph over
power-robbing hot spots and friction, give you more complete combustion,
faster all-weather starting, more power from less fuel.
