Dan, glad to see a fresh thread. I think it will be beneficial.
Let's begin with ALL information.
You mention module inside of the ignition distributor.
Can we be clear that this is a Mercruiser TB EST Ignition system? There are several TB systems!
est no points outside dis cap #J1171, ordered from merc dealer).
Can you mention what year model for us?
1986 wellcraft 200 classic
Can you mention which module is being used?
merc dealer ordered and i cant find receipt, will open dist cap and look. will also look at the top cap and make sure there is no wear in the cap leads.
(different modules provide a different advance curve/limit...... also, a malfuntioning module may not be offering the necessary advance)
No, or Inadequate, Ignition Spark Advance..... and NO Power! Simple as that!
If Merc TB, are you aware that the ignition coil is specific for this system?
Hmm, ordered from napa coil #1103 could be the culprit
Can you bring us up to speed on your Ignition timing procedure that you used?
Did you use the OEM procedure for setting BASE or Initial Advance?
did the base 8btdc and curve 32 btdc
Did you use a marked off balancer and strobe light for dynamic timing?
yes
Did you record any advance data? (you can actually plot out a curve on paper)
How about carburetion? Which type/make/model?
rochester 4bbl reman
Which boat.... hull length, etc?
wellcraft classic 200 20ft open bow. merc 5.7 350 ramanufactured, installed 2006 with reman carb, new heads, new manifold (vortec)and a new alpha 1 reman outdrive
The more info.... the better!
I agree, the true test will be with the engine installed and under load. But the ducks must all be in a row prior!
took engine out to replace oil pan gasket. want it running right before installation
