Fits MerCruiser Alpha One Gen II sterndrives, 1991 onward. JLM Marine model 1901 is a model-specific, 316 stainless steel skeg guard. It fits over the skeg below the lower unit. It is not a boat-hull keel strip.
Check before ordering: Alpha One Gen II and the earlier Alpha One / Gen I use different guards. This model is not for Gen I or Bravo drives. Confirm your drive generation and compare the skeg outline with the model 1901 photos and dimension drawing.
Fitment
- MerCruiser Alpha One Generation II sterndrives, 1991 onward.
- Aftermarket cross-references: Megaware SkegGuard 27031 and Panther Safe-Skeg 35-SS610. These are aftermarket reference numbers, not Mercury OEM part numbers.
- For replacement lower units or uncertain drive identification, confirm the actual gearcase and skeg shape before purchase.
Product Details
- JLM model 1901, marked on the guard.
- Marine-grade SS316 stainless steel with a polished finish.
- Two mounting holes, a drain slot and a folded wear edge, as shown in the product photos.
- Kit photos show the guard, mounting fasteners, two Allen wrenches and a drill bit.
Before Installation
Confirm the fit before drilling. A damaged skeg must retain enough sound material to support the mounting hardware. Follow the instructions supplied with your kit; do not install if the contour or mounting position does not match. Ask a qualified marine technician if you are unsure about the fit or condition of the lower unit.
This guard is intended to reduce skeg wear. It does not guarantee protection from collisions or repair a structurally damaged gearcase.
