Frank, a couple more things to add to your check list for diagnosing smoke at
cruising speed: One is poor fuel quality or gunk (water, diesel and algae) in
your tank. Changing fuel and replacing filters is an easy way to rule this out.
The second is a rusted exhaust mixer on Yanmar GM series
I have four fore aft mast step spacers on my 35-2 and would like to know where
the base of the mast should go to make the boat go fast.
Cheers,
