Atomic 4 issues


 

Hi Ned,

There was just some discussion on the Cal Sailing list of electric
outboards. That might be a thought. Main downside seems to be range,
which is not an issue if you're just pushing into and out of the slip.
My Kubota diesel, with a fair amount of maintenance, has been reliable
so far, but I try to have backups for things so there's a long shaft
55 thrust-pound Minn Kota stuffed in the starboard cockpit locker.
That does move the boat, and being able to swivel it to steer is
handy. This is more in the $200 range than the $2000 range. It has
its own single 12 volt battery that also runs a backup bilge pump.
I'd love to be able to pop it on to get in and out of the slip and
keep it stowed otherwise, and not have any other motor but I'm not
that confident right now.

An outboard isn't a great fashion statement but my two cents is if you
aren't going to do whatever is needed to make the inboard happy, go
for the outboard and save grief and money. Or if you want to keep an
inboard that's not completely reliable and just have a backup to
possibly have to limp in when its calm, a simple, cheap trolling motor
can work.

Higher end, people here are having good luck with Torqeedo outboards.
That and
start at about $3,000. The club has a bunch of gas powered outboards
and they're unreliable at best and only as reliable as they are
because they constantly get run and get fresh gas, and people get
trained on dealing with them. It seems like around 9.9HP or so,
companies try to make them at least a bit reliable, but below that,
it's like a lawnmower with a propeller. I'm not sure I'd trade the
diesel inboard for a gas outboard because that seems like trading one
set of maintenance problems for another.

One other person who has posted on here has gone electric inboard, had
good thing sto say about it, and I'm thinking about that too. Last
time I was hauled out in a DIY yard, someone there had a Westsail they
were refitting including installing a
electric, and it sounds like it's served them well. It's a lot fewer
potential points of a failure and a lot less expensive than a new
diesel, but then HP and range each come at a premium, which could be a
good trade off if you're just pushing in and out. I can definitely
relate to wanting to do less work on things and more sailing.

Good luck!

This is my 2nd summer with Rocinante #760. Sadly, I've spent many weeks
unable to sail because of issues with my Atomic 4. When this engine runs, it
purrs and provides excellent power. But too often it refuses to behave as it
should. My latest predicament is that it is stuck in forward gear- no
neutral, no reverse. My mechanic, who is very knowledgeable of Atomic 4's
(especially mine) is puzzled, and we have been speaking with Moyer Marine to
try to understand the issue.
I feel that I have 4 options: 1- repair the Atomic 4 (again; pull the engine
to make the repair; and what's next?); 2- repower with a rebuilt diesel
(hard to find, unreliable); 3- repower with a new diesel ($$$$$); and 4-
install a motor mount on the transom and convert to an outboard (9.9 HP?)
(reliable, easy to deal with issues, open up space where the Atomic 4 is
now).
Since I'm approaching 70, my excursions are not extensive, and my priority
is reliable power to get me into/out of my slip or anywhere when there's no
wind. I can't believe that I'm even considering option #4, but it just seems
to make sense.
I'd love to hear any thoughts. Has anyone changed to an outboard to power
their boat? Please let me know of any downsides.


 

When my A4 reaches the point where it is not worth fixing, I will probably install an electric inboard. The big cost with electric propulsion is the battery system. But all I need is enough range to get in and out of the slip. It doesn't take much battery power to move a T27 in and out of the marina in a no wake zone. It takes a lot of power to get up to hull speed. It takes a lot less to go a knot or two.

Using a diesel just to get in and out of the marina is a diesel engine's worst nightmare -- because it never gets up to operating temp.

If there is no wind -- then I don't know why I'd leave the slip in the first place :p If the wind dies while I am out sailing about -- then I guess I'll just have to wait it out. I'd rather spend a night sleeping on the water now and then than spend a couple weeks and lots of $$ on engine repairs all the time.

I've sailed a lot on Colgate 26s with outboard motors. They are flakey, tend to clunk around on the motor mount a lot, and look ugly. But it gets the job done. It does mean less drag -- plus you can glass over some holes in the boat and reduce your chances of sinking due to a failed seacock.

If I definitely wanted to be able to motor a significant distance -- then I would install a diesel. But.. I really don't want to install a diesel.

Jeremy,

I made a custom stainless offset and used a motor mount and can put on a nice Honda 9.9 extra long shaft that places the prop at the same depth as the inboard prop. ?Works well. ?Not particularly attractive but very functional?

Thanks Scott-
Your ideas are really helpful, and I've spent the afternoon looking at the 2 websites you mentioned. Electric makes the most sense for my needs, and now I just need to explore the details, whether inboard or outboard. I'll post what I finally decide to do, but thanks for your suggestions.

Thanks Jeremy-
I just can't spend more on an A4 that I can't depend on. I agree- electric has a lot of benefits, and I hope that I can make that work. And I really don't want an outboard hanging onto my stern, regardless of how much sense it would make.

Thanks Steve-
It does make a lot of sense!
