as for the dust getting in the bulkheads
a serie of bulkheads form a little cone at the 2 halves
connecting space
and dust could get in, especialy in the ones at the rear
you can put some grease or silicone at the edges
or grind the cone level
just use a little file and grind off material... in the middle only!
and again not to much, just enough ..to make sides +- equal
5 minutes work is all it takes..but take it slow and check
every dozen strokes of the file
(see images)
you can also dremel the arms U-way
at the points where the outdrives hit them when using much antisquat..
the new bulkheads coming will have all issues fixed ..
