Mallory 221B Distributor Flat Marine Review

Using this ignition part, our automotive team found that our boat's ignition system was PERFORMING better than ever before .The increased spark output helped ensure smooth starting and improved throttle response. The 221B Distributor Flat Marine was easy to install and provided a noticeable improvement in performance. The only downside was the price, which was a bit steep compared to other replacement options. Overall we were highly satisfied with this ignition upgrade..

So far so good. Used on my 1969 GM Chris Craft stationary outboard motors to replace Sierra covers that keep flexing on the engine block, causing the spool to overheat and causing the engine to stall. Now the engine runs smoother and smoother without jerking. A little more expensive, but much better.
