Even after installing a set of new pintle bushings, there was
play in Ballerina¹s two transom gudgeon/rudder carrier joints.
I eliminated this play by converting the rudder pins to bolts
and adding bushings to the transom gudgeons.
I did this conversion in a few hours
with the boat in the water. Pulling the rudder pins, I removed
the rudder carrier from the transom gudgeons. It was not necessary
to separate the rudder from the rudder carrier.
Drilling out the upper and lower
stainless steel transom gudgeons to fit the minor outside diameter
of a standard pintle shoulder bushing, I then set new bushings
into each gudgeon from top and bottom with epoxy putty, the bushings¹
minor diameter ends flush to the inside surfaces of the gudgeons.
I dropped-in the new 14mm bolts to align the bushings while the
• 2 - 14mm x 80mm stainless steel hex head bolts
• 4 - 14mm stainless steel washers
• 2 - 14mm Nylock stainless steel nuts
(MMS & Accessories, $13.26 + shipping; 800

• PC-Marine epoxy putty (Ace Hardware, $5.69 |
• Silicon Grease, waterproof (Ace Hardware, $2.99)
• 8 new pintle bushings
I also epoxied bushings into the
aluminum rudder carrier, dropping-in the rudder pins to hold them
in alignment. The epoxy putty fills voids and holds the bushings
in place during final assembly. (Puttied-in bushings can be separated
from metal with a sharp blow.)
After the epoxy set I installed the
rudder carrier in the transom gudgeons using the 14mm diameter
hex head bolts, washers and Nylock nuts. To maximize the bolts¹
unthreaded shank length inside the bushings, I used 80mm long
bolts cut to the length needed to accommodate the washers, bushings,
gudgeons and nut. I silicon greased the bolts¹ shanks before
Ballerina now has a sensitive helm.
The 14mm bolts and nuts are tightened just enough to eliminate
play. I¹ve needed to adjust them only once, soon after installing
them six months ago, loosening them slightly. The tiller is strapped
to one side when the boat is not in use to minimize wear on the
bushings. To date, she has been outside the reef in up to 25 knots
of wind and 8 foot seas with this modification, without problem.
Ballerina has the wing keel and her
rudder extends about 6 inches below it. I reinforced her hull/transom
joint a year ago. The drilled-out gudgeons now seem the most likely
to shear away in a catastrophic grounding of the exposed rudder.
By the way, I raise the rudder a
notch when cruising the shallow backcountry here. Silicon grease
and Teflon tape on the nylon bolts¹ threads has kept them
turn-able, so far.
