'89 Tristar 190, 351, 1:1. Just got the parts from skidim, and am tackling the project tonight. Is there anything magic about this? I read somewhere (probably on this board) that I need to put some dielectric grease on the rotor, and also have to gap the points correctly. If so, does anyone know the correct numbers? And is there anything else to look out for? I'm sure this is pretty basic stuff, but it's been 20 years since I did this (ouch, that hurts). Pontiac Grand Ville, 455 - because a 454 was just too wimpy. The good ol' days. :) Thanks.

Send the points back to SkiDIM and have them send you an electronic ignition kit. Replace the points with electronic and then you don't have to worry about gap dwel etc. Best $90 you will spend.

I have never greased the rotor.

Electronic igintion is the way to go. Did it on my 84 nautique which I owned previously - started and ran like a champ and no more replacing points? Cost is right too!

One more for the electric ignition. Simple install and gives you improved performance. In my mind, the way to go.

Electronic ignition is the way to go, minus the plugs, my last tune-up took about 10 minutes, and that included atleast one trip to the fridge for a fresh beverage. :uglyhamme

Conversion to electronic ignition is worth while!!

The best thing about them is when you call to place an order - if you have ANY questions, they really know their inboards. Not just boats, but inboards like ours. Can't beat 'em.

Check the springs and weights in the distributor cheap to change...and mark the orientation of the distributor before you take it out....from a carb loving points guy....course I was going to convert but with my motor Vince said I needed to change my whole distributor....so until I have a problem....I can justify. :uglyhamme

I think I bought them from Mr. Gasket....but if you change the springs the weights should be reused unless you want to change the advance...different springs would change the advance too....it was a distributor rebuild kit I think...cheap

I still run points on my 84 351w. I like the simplicity and only change out every 2-3 years, and then only because I'm bored. Nothing against the electronics, but I'm an old mechanic and like the fact that if anything goes wrong, I can fix it and get home. Only fried a module once, and I don't know how to fix'em.

I just did the electronic ignition conversion in my 89' Tristar 190, and this is definitely the way to go. I contacted SkiDim, and will be doing all available business with them from this summer on out. I tried to get a variety of parts from my "local" Mastercraft dealer (over 100 miles away, and I live in New Orleans) with NO sucess whatsoever. I even contacted differect MC dealerships around the states, with the same issues. Electronic, faster start, better overall operation!!

adkins1966,

Nice to see someone else here from NOLA. Where do you ski? I used to see someone in a Tristar on the Pearl River Navigation Channel was that you? Not many inboard owners around here.

I'm surprised that you had problems with the "local" dealer. They have been great to me although getting parts for the older boats is usually best left to SkiDIM.

PM me if you are interested in doing some skiing. I am always willing to ski with someone else.
