Review on Sierra International 18 5181D Marine Ignition by Mick Ohlrogge

This part did not fit my engine when the flywheel was installed it turned 2/3 when turned by hand and hit something. After checking the lease a half dozen times, I found that it was a hit of a new coil. To make sure it was the problem I installed an old spool that was bad and turned the flywheel with no problem, this should be the OEM #. Replace 0584477. (Please contact me) this was installed yesterday
