(water penetration into the cylinders caused lock up) Engine involved is Starboard
Installation. My question is , what is the standard rotation for a Chrysler 440 viewed
from the flywheel. The port engine turns counter clockwise as viewed from the flywheel.
Our answer:
Chrysler Marine engines were basically Automotive
standards and I quote: "Propeller rotation is as viewed from the drive end and engine
rotation is as viewed from camshaft drive end". This often caused confusion in the
marine industry.
What you need to look at is the engine serial number plate
and at the firing order. For R-10, R-13, R-15, R-25, and R-30 the firing order is
1-2-7-5-6-3-4-8.
For L-10, L-13, L-15, L-25, L-30 the firing order is
1-8-4-3-6-5-7-2.
Unfortunately the L-19 has a firing order of
1-2-7-5-6-3-4-8, and the R-19 has a firing order of 1-8-4-3-6-5-7-2. The reason for this
being that the R and L really stand for the prop rotation and not the engine rotation.
Which is one and the same except for the L-19 and R-19 engines.
No problem right?
