A perfect match prop (pitch and dia.) plus the
installation of an adjustable carburator main jet will make these old
engine very efficient 'fuel-wise'.


I found my A/4 going down the ICW was using about 1/2 gallon/hour, though I
wasn't pushing the boat speed. The only problem I had was that aftermarket
fresh water cooling pump. I eventually took it out of the loop and used the
engine raw water cooled just fine.

I would like to thank the group for their replies. I now know it is more
than feasible to take my Grampian 30 with its Atomic 4 down the ICW. Some
great tips about what to watch out for re fuel and water pumps, prop pitch,
carburetor adjustments, fuel costs, mechanics' knowledge, and more. Thank
you, people, for helping make a dream come one step closer to reality.

Has anyone gone the length of the ICW with an Atomic 4 as their engine?
Were
there any problems? What was the state of the motor like at the end of
the
trip?

Many thanks.

Barry,

We travelled last year from Toronto to Cuba and back ( Erie Canal,
Hudson River, ICW most of the way down and back) with an atomic 4 in
excellent condition prior to leaving. Total engine hours were approx
850 for that trip. We had to replace the water pump and electric fuel
pump, in the Chesepeake. Otherwise the engine was completely trouble
free. We will need an overhaul this year however.

The only real concern for us was the excessive fuel cost relative to
diesel!

Cheers,
Kevin

If you aren't already on it, I have found the Atomic 4 list on Sailnet
to be an incredible source of knowledge, advice and practical help on
the care and feeding of the Atomic Bomb.

Treat it right, and it will outlast the boat it sits in. And, like
your Mamma told you, remember to flush.

....... but if possible never let it 'dry out'. Always leave it full of
cooling water. Especially the exhaust manifold will form huge
"platelets of rust" if its left to "dry-out" for long periods ....
just like most cast iron. ..... same reason that Navy ships hardly
ever fully shut down and let the engine cooling water systems drain.
