I have a pair of Mercruiser Thunderbolt IV ignition modules for sale. They are the units that attach to your riser, not the units that attach to the side of the distributor. They are for either small or big blocks that require 22 degrees of advance at WOT (plus base timing). They are V8-22 modules. Perfect condition. Clean and work perfect. Only have 1.5 seasons of use on them.
$200 each + shipping.
PM me for pics and/or details.
