Hey, your in the wrong section, but we had a force 125hp why do you think its the starter? Are you sure the batterys are fullly charged,are all the battery connections tight, starter motor connections tight, we had a fuse that would blow and you need to reset it.push button fuse. there was a neutral safety switch that would get out of adjustment,starter wouldnt work.
,there are huge starter motor companys on line, you need to remove your starter and know exactly what it looks like so you can find it by looks. You should start with a google search" starters" they will pop up.
