I think there is a power to rpm curve in the a 4 owners manual. I never
run my a-4 over 1800 and usually cruise at 1200- 1500 rpm turning a 12x6
two blade . It pushes the boat at 4.5 to 5.5 knots getting very good economy.
The gas engine is very smooth. I would consider a new or recent diesel installation
an upgrade, an old worn out or poorly done diesel install would not. All
things being equal if I was looking at two identical boats one with a worn-out
buhk and one with a worn out A-4- I would choose the buhk because after a
rebuild the boat with a diesel is more valuable. .....<br>

<div><font face="Arial" size="2"> I can't really comment on the Bukh deisel
since the A30 I had was wquipped with an Atomic4. What no one has mentioned
is that the A4 is 30 HP but only at 3000 RPM. At normal running speeds of
15 - 1800 RPM it is considerably less. I forget exactly what the number
is but I think it is somewhere around 15 HP. If the Bukh is running near
it's capacity (which is good for deisels) the difference between the two
is not that great. Of course, that would also mean that there isn't a lot
of reserve power left in the Bukh. On the A4 side, there isn't a lot of
reserve power either since most boats (almost all A4 installations) can't
rev up much higher anyway do to constraints of prop / hull / transmission
ratio design.</font></div>

Thanks for the feedback. The installation is original and the man who
owns the boat used to work for Whitby boats and knows them quite well.
My real question relates to the power issue and that is - does the Buhk
have sufficient power for extended cruising in the Great Lakes. I understand
the economic and safety issues of gas vs diesel but my concern is the
power issue and the fact that the Bukh is only a single cylinder engine.</font></span></div>

If the boats are similar in price, condition and options, I would
purchase the Alberg with the diesel. The motors are more fuel efficient,
safer than gasoline and command a greater price on resale. I would make
sure the installation was done correctly which includes a fuel/water
separator in the fuel system, water in a diesel will cause all type
of issues with the fuel system.</font></span></div>

For those of you who are more familiar with the A30 variants I have
a request for your input. I am looking at two similarly equipped
A30's one has the buhk diesel and the other has the atomic 4. With
out wishing to offend anyone, what is the opinion as to which one
I should give the greater consideration. My main sailing will
be cruising Lake Erie and eventually the other Great Lakes and the
Northern Channel for several weeks at a time along with my wife.</font></span></div>
