Dear listers,
                  Just have to throw my ten cents worth in here. I 
replaced my Atomic4 with a Sole Mini26 Diesel this last winter. I have 
nothing but good things to say about this little workhorse. Three 
cylinder, 26 HP output, maximum revs 3600. The prop was sized to a 
twoblade Mickey Mouse ears 12" x 9.5 pitch. This gives a hull speed of 
6.5 knots at around 2700, which is plenty for me. She got a real test at 
Dodd narrows when I forgot to allow for Daylight savings and "went for 
it" an hour early against  the current which was flowing at around 6 
knots. Got through at 1.2 knots at 3000 revs. Slightly shaken but 
absolutely delighted! At cruising speed ( 2150revs- about 5knots plus) 
she is burning 2 to 3 litres per hour. She has very smooth running and 
makes less noise than the old ABomb. Highly recommended. Regards 
Jonathan Whittingham    Alberg 30 "Emmy"
