Mike,

Can you start with one ski or do you have to drop one after starting with
two?

I also converted to diesel a number of years ago (can it be 15 years ago?).
I chose a Unviersal M4-30 (4 cylinder 30 HP). Talk about overkill! Not
really, there have been many times that I have been happy to have the extra
power. This engine was chosen for different reasons. My original intent was
for a 3 cylinder 18HP (which I think is a ideal coversion), but I could not
find one that match the mounts on my A30 which would neccesitate serious
surgery to install. The M4-30 has all of the same critical dimensions as the
Atomic 4 and weighs about 40 pound less. Just because you have 30Hp with
lots of torque from a diesel doesn't mean you have to use it all of the
time. The engine is quiet, smooth and burns about 1/2 gallon per hour. Then
when you need to tow another boat, move a raft, extract yourself (or someone
else) from a grounding or fight large waves, currents and headwinds in tight
waters...you have the power to do that. Then of course there is always
wather skiing behind an A30! :-)
