RH or LH??

Use only a distributor designed for marine use. Do not use an automotive distributor no matter what direction your engine spins. Distributors for boats may cost a little more but they are designed to minimize the possibility of an explosion. The hazard is that your marine engine runs in an enviornment where gasoline fumes can accumulate as opposed to an auto where the engine is exposed and ventilated to the enviornment.

This may be the most important information you ever get from this site.

I would like to answer your LH/RH question but any answer I give you stands a 50% chance of being wrong.

I live for it.

you can get a marine version msd box, summit will have them, the options for distributors are a little less, I would include some links but its late and I am sleepy.. I am sure someone will come through with them..

gregr1971, I'm assumming that you are referenig to the motor in the ski centurien and it is a standard rotation left hand motor. You have to look at it from the rear facing forward to get the rotation correct, well it easier that way so as you stand from the rear the engine would be spinning to the left thus left hand rotation. As far as the distributor goes on a 351 LH/RH rotation engine the dist. will spin the same way the only difference is the gear on the dist and cam and the last time I checked MSD does not make a marine grade dist for the 351W engine and you will ahve to use a mallory unit ylu-554-cv or dv depending which direction the engine is.

Greg,
You can tell if you have a right or left hand drive by referring to the Engine Model Identification tag, which is attached to your engine. The third place(letter) under the "MODEL" will either be an L (for left hand rotation from the rear) or an R (for right hand from the rear).
Let us know which route you go with the distributor and how it works. I'm actually looking to replace mine as well and would like to know the ups as downs with my options.
Good luck!

screw the model number you don't need that sh*t to figure it out.

You have a standard rotation motor thus the left counterclockwise prop rotation ok got it?

The "L" part of "L10" designates the prop shaft rotation.

The "PLD" indicates left hand rotation (standard or automotive), Ford 351cid/5.8L, 4" bore, 3.5" stroke, 8.3:1 compression ratio, 240 HP. Or something similiar.


I do not have information on the "WR and the "10"

I knew I have seen this before. Curious that my manual list "D" as 240HP above it lists "D" as 255HP. Things change, I guess.

My engine ID # is PLD PR R12PTT. So, I can figure out everything except the "PTT" part.

Thanks guys this explains in detail. Did I mention I love the CCF Forums?

79 thanks for the info- you have a way with words! I'm a 20+ military man, do I remember seeing you with a drill instructor hat on?

20 yrs military...obviously not specializing in mechanics.

Push To Trim, at least thats what it is on O/B controls.

He he .. that's great stuff! I saw your boat pics on the reunion board. You should be ashamed of having that much talent. Notice that pictures of my boat are from ...far away!
