[Alberg30] Atomic v/s Buhk

[chrishardy]

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. .....
