• You may have also heard that the front propeller was hitting on the
bearing carrier causing some surface rub damage.
• It was found to be several issues.
• 1) The ID of the front propeller is now opened up by an additional
one hundred thousands per side to eliminate any possible rub.
• 2) The propellers were not within the balance specifications of the
print and were adding to the oil seal leaks as well as the hitting
on the carrier.

of porosity in the casting that was hitting on the bearing carrier,
Devcon is a filler material commonly used in most all of the
Stainless steel cast process propellers as a filler for porosity.

out of the bottom radius of the bore causing some of the rubbing.
