Hello, I am new to the forum and I imagine this question has been answered before but I have not figured out how to search the boards yet.
I purchased an 1984 MasterCraft last year and am about to do some work for this season. It still has the original distributor and I want to upgrade to an electronic distributor. I would appreciate any recommendations you may offer as to brand, part number, a good source etc. My boat has the 351W motor form PCM. LH rotation, power slot. If you have a recommendation for engine/ignition timing I would appreciate that too. Thanks

I lot of people here like petronix ei kits, me personally I like Mallory products, so I swapped out the points for Mallory's EI e-spark kit http://www.summitracing.com/parts/maa-9-26902 , Then I did some top end work and I used the unilite YLU554CV, and it's adjustable unlike the old prestolite that's in there now.

Base timing 10 degrees BTDC
I did some trial and error with this dist. my setup liked 30 degrees of total timing @ ~3000 rpm's
Some people say 34-36 degrees of total is advised but my engine didn't like that much timing and I actually picked up some rpm's at 30 degrees.

A MSD Blaster 2 coil with a ballast resistor completed my install.

A marine UL rated distributor is mandatory

I personally went with the Pertronix plug and play marine billet distributor found here:

Here is a pic in the motor. By the way, my boat is an 84 as well. The distributor works GREAT! No problems at all. Love it! I know its difficult to see the distrib, but I just love to post pics of this beautiful powerplant.

Thanks very much for your replys. I am going to pull the distributor today and take it apart. If it looks rebuildable I will go for the pertronix kit including a coil otherwise I will shop for a distributor based on your feedback. We bought our '84 last year. It had been in storage for some years and needed work. This is our third MasterCraft ('79 and '93) and I always preferred the wakes of the early years. We had the upholstery redone and I did a quick tune up just to get it out on the water a couple of times before the season ended. It is on a Correct Craft trailer so I had to modify the bunks and fab a vee up front. I am replacing the stars and having the prop checked out and we will be ready for the season. Thanks again for your help.
