HI,
Have a chevy 305 marine engine with a distributor that still has points, am looking for advice on converting it to pointless, as well as a hotter ignition system.............thanks

HEI. Available anywhere.. Check Summitracing.com Make sure to mention it's a marine engine - otherwise you'll be firing backwards.

All you need to do is get rid of the ballast resistor and rest is drop in.

Same as any points-based system. Crane, MSD or Pertronix.

For ignition boxes, there are too numerous choices. The above brands have several offerings.

We did this to a pair of Chevy/VolvoPentas some years back; as I recall we used Mallory distributors from Summit.

The units were completely self-contained (optical??), so it was a matter or swapping them in and hooking up a couple of wires and timing the beasts. These units also used the standard-type plug/coil wires that the points distributor used. Gawd I remember that project, the boat wasn't even a year old and would eat points every other month; after the swap life was trouble free.

HEI..

Simple to install and easy to find.

See if you can get yourself an old Mercury Thunderbolt IV ignition, they are awsome and pretty cheap.
