W8ye this should have went to you My starter is a Mini Max Gear reduction starter 12 volt, its supposed to be able to crank a 140 4 stroke easy ,all I know for sure is that it cranks my 120 YS without any problems at all.This is there home page and part number www.Maxxprod.com ACC1521 Electric Gear Starter.I like it because its powerfull plus it is small and doesn't take up much room in the flight box.
