Fitment and Purchase Checks
Covers the Mercury four-stroke V6 and V8 family. Verado, Pro XS, Sea Pro, 175 through 300HP. Mercury goes by serial, not model year. 2B529482 and up puts you in range, and the 300R starts at 1E080500. If you've owned one of these engines long enough, you know the original starter gets sluggish after a few seasons, especially on boats that sit in water. One boundary worth stating clearly: this is the big V6 / V8 starter. It does not cross over to the smaller 2-stroke 30-150HP applications or to trim and tilt motors, which people sometimes mix up when searching by horsepower alone.
Why This Unit
Now the honest part. Pinion and rotation details come from compatible replacement listings, not from Mercury factory prints. We haven't verified every dimension against OEM drawings, so we won't claim we did. Match the removed unit before ordering. Teeth, rotation, mounting flange, solenoid position, all of it.
