I have an 89' 3.7L Mercruiser 470 and just purchased the alternator conversion kit. The instruction say I have to pull the Harmonic Balancer and fool with the Stator and such. When I first looked into this conversion I read another set of instructions that say to just clip the wires off the old system and remove the old voltage regulator. So do you think I need to get a puller and remove the harmonic balancer?
