88 351 dist cap, rotor set up

[Cbower83]

I'm looking to buy distributor cap, rotor and condenser for my 88 comp. has pcm 351. The copper contacts in the cap now have a lil corrosion on them and have gashes from the rotor hitting some of them.... Is that normal?! The boat runs real ruff at idle and wants to die. Then I found the problem with the cap etc. so I found the napa part numbers that were posted on a thread for this but should the cap have a vent at the top so that it helps with corrosion build up? Thanks!

hey cbower...i don't have the part numbers but you will prob find a tune-up kit at your local nautique dealer. they run pcm engines and have the parts...at least the ones around austin do.

Ok cool. Ill look some up tomorrow. The part numbers I have are from napa auto.

You can use napa caps and rotors, doesn't need to be PCM OEM. A nautique dealer will also have the correct PCM parts, but they are not fundamentally different to my knowledge. I have used a cap and rotor for a Ford F250 on my GT40 engine for 4 years now without skipping a beat.
