87 2001 PCM 351 Engine Rotation Question

Depends- what parts are you talking about?

Don,
I see you have visited and are still be coming up with the parts you need so, I do have a suggestion. Get in touch with Zach at N3. He can help with just about any part you need and if not, point you in the correct direction. Tell us what you find out and as requested, what you need.

351W parts that are the same between a standard rotation auto engine and a Marine reverse rotation engine

-Intake manifold and gaskets. Careful selection should be taken.
-Cylinder heads and gaskets. Careful selection should be taken.
-valve covers and gaskets.
-Thermostat (as long as it opens at the correct temp 140)
-Thermostat housing gasket
-valve train parts; rockers, push rods, valves, valve seals, lifters
-timing chain cover and gaskets
-timing chain and gear
-pistons, rods and rings. Careful selection should be taken.
-crankshaft and bearings. Careful selection should be taken.
-Exhaust manifold gaskets
-flywheel ring gear
-oil filter
-Belts (if you can find the correct length)
-PVC valve
-spark plugs
-spark plug wire sets
-brass freeze plug sets
-oil pump
-oil pan gasket

Reverse rotation specific parts

-rear main seal
-front seal
-harmonic balancer
-distributor gear
-camshaft
-water pump
-starter
-transmission
-prop

marine (safety) specific parts for either standard or reverse rotation

-Distributor
-Alternator
-fuel pump
-carburetor
-starter
-fuel hose
-cooling hoses

There are water pumps (engine) available that are bi directional. Yes, the starter needs to be a RR. There have been several here that have gotten into trouble by purchasing the wrong rotation and guess where! Autozone!!! The post usually goes something like this: " I'm trying to start my engine and it seems to be pumping air out of the carb instead of sucking air in. What's the problem" Then the typical question is: Have you replaced the starter?" Then the typical answer is: Yes, I bought one at Autozone." BTW, if you do have a starter problem, my first suggestion is to open it up and take a look at the brushes and commutator. Many also take their's to an auto electric shop where they have the "growler" to check the armature.

If I had starter issues I would most assuredly carry it first to out local electric motor rebuilder here in town and have him check all the windings , armatures and brushes knowing now that its a reverse rotation specific starter.

Mark's explanation is a little confusing. The directional wick lines on the crank are more of an imprint. Think of the knurling process on a lathe and not machining in a grain direction.
