Spark Trouble
 

Anybody Know Thunderbolt Ignition Glitches? Out Checking My New 3 Blade And Ignition Today The Prop Shows Some Potential Running 50mph At 3000 Rpm But Went To Stop For A Beverage Shut The Motor Down And No Spark For A Restart! 20 Minutes Later The Spark Has Returned And Runs Ok Only To Shut Down To See If It Happens Again And Sure Enough No Spark? Could It Be The Module In The Distributer ? Msd Recommended Mounting The Coil Uprite Could Be An Issue. The Also Said When A Box Goes They Dont Come Back So Thats Out. It Must Be Running For Superfest.

MiKe Had The Same Problem On A Customers Boat Was The Pickup In The Dist// I Have My Coil Sideways No Problem// If You Need One To Try I Got Em In Stock///

Re: Spark Trouble
 

I agree with lightspeed, change the pickup first. I would also check for a crack it the coil...

Re: Spark Trouble
 

New Coil And Install Missing Ground Wire To Bottom Of Distributor With No Effect. Still No Restart After A Shutdown, Going To Replace The Mod In The Dist Next. I Did Spot Rick In The Mako. 50 Is Fast For A Mako With A Single.

Hey Zup,
Check the wiring of your ignition circuit (purple wires). I had a strange problem with an ignition switch once.
I finally replaced the switch and the purple wires to and from.
When she won't restart, see if you are getting power to the coil.
Do you have a full MSD system or is it an add on to a Merc Thunderbolt? You could try without the MSD box also; I've heard guys have funky things happen with those too.

hey zup was that u in front of tanner yesterday at about 5. If so I was the white 21' taking a blast. :D

Re: Spark Trouble
 

Hey Zup,
Get the spark thingy figured out ? And are you going to make Superfesst at Robert Moses ?

Re: Spark Trouble
 

I was out wednesday nite around 5-6. I have the new thingy for the spark installed just need to recheck the timing and hopefully im good. I would much rather make moses than claudios. We need a boatcount for either.

Hey Mike,
I'm going to be in Baldwin (sp) Sunday afternoon through Monday.
I may be able to escape for a couple of hours.
Please PM me your phone number.

New Distributor Mod And Still No Restart After Warm. Whats The Next Guess Msd 6al Or Merc V6 Box ?

Re: Spark Trouble
 

Mike, good luck with the boat. :(

Re: Spark Trouble
 

Start it up at night and look for sparks or arcking of your wires, same thing happened to me in my 24' Super I/O last year: MSD coil had a crack in the porclin.

Re: Spark Trouble
 

What's next Zup?
DUI sells and new Billet Distributor with built in coil and module for around $300. To add the rev limiter is about $120.
I have only heard good things about their stuff...

Re: Spark Trouble
 

Going To Start From Scratch. The Plugs Are All Fouled, And Thats From Just Running It At The House. I Moved The 6al Box To The Motor To Eliminate The Boat Wiring.the Weather Pacs Worked Well For Bypassing The Msd Box. If It Craps Out I Can Bypass It. This Problem Needs To Walked Away From For A Day And Reverify Everything. Its Like A Speedmaster Drive Install You Can Try To Put It On For An Hour With No Success, Walk Away Come Back In An Hour And It Goes Rite In .

VERTEX spark every time!!!!!!!!!!!!!!!!!!!1 tripps

Re: Spark Trouble
 

We can relate that statement to a lot of things... :rolleyes: :eek: :drink:

Re: Spark Trouble
 

starts every time now. now only the weather is keeping me from checking out the new prop numbers.so far the slip is down from 15 to 9.9 but no good top end numbers yet.

Re: Spark Trouble
 

So what was the problem bro?

No good top end numbers yet??? :p
I'm sure she faster than my boat by a lot... :D
Care to share those, "no good top end numbers"?

Re: Spark Trouble
 

Dont Know What It Was. But Its Gone Now. Motor Still Running On The Fat Side. Was Able To Clean It Up A Bit. With A Rejet And Smaller Power Valves. Only Wacked It Once And Not Let It Build Some Steam Yet, So Far Just Touched 87 But The Rpm Was Down A Bit. Those Mufflers Do Kill Some Rpm

Re: Spark Trouble
 

Mike, I forgot, how much HP you running ????

Re: Spark Trouble
 

Hey Gary,
He's running with more than us for sure... :D :p :drink:

Re: Spark Trouble
 

The Motor Was Not Dynoed After The Changes . Installed New Aluminam Heads Another Carb And An Air Pump. All Small Still Fits Under The Flat Hatch. I Think The 18 Inch 3 Blade Prop Helped Alot.

Re: Spark Trouble
 

Hmmm...
Didn't you lower the engine a bit when you installed the speedy? :evilb: :p :D :drink: :D :cool:

Re: Spark Trouble
 

Yes The Motor Was Able To Go Down 1 Inch For The Proper Drive Height. With The New 10 Quart Canton Pan I Had To Install A Shortie Bildge Pump. The Shaft Is Now 1 Inch Below The Bottom . The Balance On The Boat Should Be Incredable.
