My brother has a 30ft Alura with a Borg Warner 72C, Serial
# 1017012, 2.5 to 1 reduction. Motor
is Pleasure Craft 350ci Chevy block.
Box has squeal across whole rev range when in gear
. Local mechanic
can't tell him what is wrong.
He has tried both ATF and W40 single
Can some one who has pulled a Borg Warner apart tell me what you think. Thanks.
