Methods to deal with groves on the propeller shaft:
# Add/re-position spacers between the seals
# Machine propeller shaft and add a 316SS sleeve to return to original size (35mm)
# Replace propeller shaft
<br>
Notes:<br>
The 99139 SKF Speedi Sleeve For 35.00mm/1.375" Shaft has been installed over the propeller shaft - this is a bad idea.  The Speedi Sleeve is not rated for continuous salt water immersion so it is not 17-4 ph (likely the propeller shaft material) or 316SS.<br>
