Re: '01 Suzuki DT70 Starter Replacement
Ahoy, Pepping.
Welcome to iboats.
Before you replace the starter, what have you done to verify that your trouble is in the starter? Three of five starters that are changed don't need changing.
When starting becomes intermittent it is most often a corroded connection in the starter high current wiring or a bad solenoid.
Your starter is pretty new to have worn out the brushes.
If you disconnect all large wire connections, starting at the battery, going to the starter and then back to the battery, and clean them carefully before reconnecting them you may find your trouble has gone away.
Good luck, and let us know what you find.
