Official 1980's Weekender/Sundancer 300 thread

So an 88 has the Thunderbolt ignition? I thought it had points... Guess I have to look at mine and see.

I just had to replace some of my system. We have a Thunderbolt VI system, mine is a V8-22 (the 22 is the advance, be sure to get the correct one) and a pickup in the distributer, plus the coil. I have a complete spare system on hand. Before anyone replaces the modual I suggest looking into replacing the distributer itself, it cheaper and removes many of these parts that fail

Anybody ever have this issue:
Port engine runs fine. Cross 3000 RPM and within 30 seconds it will lose power, like about 1000. Then it recovers. Then lose power. Recover. Rinse. Repeat.

I had a similar issue on my last sundancer with twin 4.3's. it wasnt as much of a rpm change but like yours it would studder/cut out at high speeds, only underway, while the other side kept on keepin on. turned out to be just a dirty/bad distributer cap and rotor.

where can you find a distributor that costs less than a ignition module, ?

[dwna1a]

Cheapest ICM....$395++, distributer lowest price was around $400 with that you replace the harness, pickup, and ICM. Pickups are $75 harness around $25

TriTone, if you get to the modual I have a spare here that I will sell to you for the price I paid. You may also want to look at your pickups in the distributer. It sounds like a timing advance issue, until you say it corrects itself. May I make one suggestion, if you find it is the modual, change the whole distributer out. It's cheaper than buying the part.

Thanks for the info and offer. I will get to the boat this weekend and hopefully take a look. At that time I will probably have more questions. When you say "pickups" are you talking about the "points?" Where is the thunderbolt module?

[Tritone]

So with thunderbolt is there a distributor or module or both?

[dwna1a]

On mine it is over on the riser, pickups are in the distributer
Sorry, I misunderstood your question. You have a distributer, in it there are magnetic pickup, and a rotor. From the bottom is the dist you see wires running to the coil and over to the ICM.

Ok, no more mechanical talk, grab a margarita and relax!
