I've have used this fix on my motors and friends several times over the years. Before you try this make sure your getting proper voltage to the starter, and that you ground is making good contact. Bad ground will eat a starter up!

So, before spending money on a replacement, spray WD-40 as you already have and let dry. Then with a can of spray grease, spray down and up into the gear shaft. By hand, work it up and down to get it all lubed up and see if it will work better.

Good people, price and warranty

Those are cheap enough to where I am probably just going to go through one day this winter and replace them all. Thanks for the advice

Simple solution:Take your starter off & take it to a starter/alternator shop. It can be rebuilt much cheaper than replacing. Any good alternator/starter shop can do it.
Its a simple fix for dependability next season.

Unless you see corrosion at the fittings you are probably just wasting your money. My cables are 31 years old in 2 weeks. Never had a problem. If you suspect the cable then test the resistance.

this ^ I have had starters rebuilt at starter shops and never a problem, make sure they check the armature and field when they do it.

21 responses of what ifs, maybe, try this,it could be, etc. Just pull it and take it to a starter/alternator shop. They can fix it in a fraction of the time you'll spend trying all of these fixes, they will clean the armature, replace bearings and brushes cheaper than you can buy a new starter and you are back on the water fishing.
You keep trying to start that motor with a bad bendix or gear, you are going to be looking at a much bigger repair job.
