<DIV><FONT face=Arial size=2>Tom, the information I have from Westerbeke
recommends cruising revs at 80% of maximum. For the M320 B this is about
2900rpm.If you look at the web site performance graph for this engine, 2900rpm
gives only10-11hp at the prop. This may be enough for lighter boats but our
A30's are reassuringly substantial and my personal opinion is that a few more hp
would be useful. My prop is a 3 blade 12x8 I think from the original Atomic 4. I
also find that below 900rpm it runs very lumpy which makes idle speed
uncomfortable.This may be common to all diesels. I read somewhere that at low
revs the fuel metering is not accurate enough to give equal injections to all
cylinders.I would be interested to know if 4 cylinder marine diesels suffer from
the same uneven running problem at low rpm.</FONT></DIV>
<DIV><FONT face=Arial size=2> I have no complaints about the fit in the
engine compartment.It seems that the mounting feet are about the same as the
Atomic 4. Tait Tait has the liner of the later models and it does not cause a
problem. Have a close look at the starboard view on the web site to see
the location of the dipstick. First time I did an oil check it took an hour to
get it back in! I suppose that sort of problem arises with engines not
specifically designed for boat installations.</FONT></DIV>
<DIV><FONT face=Arial size=2>If you could get performance figures and dimensions
of the comparable Yanmar that would be a useful comparison.</FONT></DIV>
