View Full Version : Distributer

Opened up distributor to explore my next project, EI.

1991 ProStar 190, Standard 351, Prestolite Distributor - Screwdown


Having never owned anything with a carb motor (before my time really), not sure what I am looking at here. Standard points setup?

Rotor did not budge with a pull and did not want to break anything. Just corroded on or is there a setscrew I am not seeing?

How about this cap? Looks corroded to me and ready for replacement.

Looks like a fair bit of corrosion all the way around. Assuming your engine's the same as mine, rotor should just lift off. Juding by the corrosion, you might need a little wd-40 up in there first. (That's why god made those flexible straws they come with.) It may need a very gentle lift with something like a paint can opener that you can get under that lip. Again, very gentle. I usuall save the one I'm replacing and file contact points clean in case I need a backup for a friend mid season to get them back on the water, but in this instance I would probably make an exception.

Looks like you already have EI. Rotor will lift off with some extra effort. It is stuck on. Change cap & rotor, spark plugs and check wires, should be good to go.

The rotor will pry up with a big flat head screw driver working from the lower plastic portion ... Just put screw driver under ....l rock left,right, move a few degrees over and repeat it will start to come up ...... Need a new cap as well ... Don't like the color of the contacts.

Not points, eh? EI already?

Probably factory, PO did not upgrade anything on boat, its all stock I have found.

Spark plugs already done, so I will do cap and rotor and call it good.

Not having to upgrade the distributor to EI just saved me $100-200. Nice.

My 91 prostar 351 had EI. May want to check the timing too. Now you have extra money to spend on some other part for the boat. :D

Yes, that is how it works!

Such a money pit, but in a good way.

I also put a dab of dielectric grease on the rotor anywhere there is any metal. I also use same grease on the plug wires where they go into the distributor cap and on the spark plugs. Check your weights and springs and oil them and their pivot points.
