I'm forwarding this earlier thread with link to stats from USGC on boat
accidents. Interesting info there, especially Rick picking out the 1 out of
86 fires occurring in a sailboat.

Very interesting statistics.
Among other things, it seems 7 times as many people died swimming after
boats or gear that had drifted away from the dock (see table 3) as had died
in fires.
Of 86 fires, only one was in a sailboat. As a matter of fact, 60% of all
fires happened in open motorboats or jet skis (PWCs).
I wonder just how many boats are registered in the US? Maybe 500,000? Call
it 250, 000 to be conservative. So the chance of a fire is something like
86/250,000=0.034%
For myself, I've always thought the concern over gas power vs. diesel on a
sailboat was way overblown. Emotional not logical. And I think it was Danny
made the case very well that the DIY installation of a remanufactured A4 for
around $4k in one day makes a lot of sense compared to installing a diesel,
tank, prop, shaft, wiring, engine panel, etc. for $10-12k.

Interesting stats from USCG:
http://www.uscgboating.org/statistics/accident_statistics.aspx
I haven't read through the entire document but from 2012:
Out of 2454 accidents related to operation of vessel, 21 were a caused by
failure to ventilate. 0 deaths.
Out of 468 accidents related to failure of boat or boat equipment, 12 fuel
system failures and 6 ventilation failures. 0 deaths.
Out of 694 accidents related to miscellaneous causes, 66 were caused by
ignition of fuel or vapor. 1 death.
I'm assuming that the miscellaneous category includes ignition of other
sources such as propane heating / cooking and perhaps alcohol stoves.
If you have a gas outboard on your boat then you already carry gasoline.
Given that the tank usually isn't internal but still I think the percentages
overall are quite low and of course those stats would include accidents
related to outboards, I am fairly sure.
When I rebuilt my A4 I replaced the old aluminum fuel tank and all my fuel
lines and fittings at the same time .... since with the engine in-place, the
old tank wasn't coming out without some significant surgery. The new tank I
can fit through the cockpit locker no problem.
I also made sure that the low-oil pressure cut-off switch for the fuel pump
was replaced and working and properly fused. The existing switch was not
working and had been bypassed!! ... I am pretty sure by a mechanic!! (since
the PO did not do any of his own maintenance or repairs).

Three years ago I was doing work up my mast about 100 ft away from a 40`
wooden Chriscraft which exploded during refuelling.
It was shocking and there was no warning for those nearby. My point - it's
more than rhetoric or something you only hear about. It can actually happen.
Second observation - a friend rebuilt his A4 last winter, reinstalled in the
spring and found out his tranny was seized. R&R all over again.
The message - take the time to go over everything and rebuild/refurbish as
necessary. You don't want to take it out twice. Of course same goes for any
engine.
3rd - my 3GM will use about 1/4 tank of fuel motoring and motor sailing for
13 hours. How will that compare with gasoline - I think there's a big
difference.
Not criticizing the idea of keeping an A4, just being aware of some risks
and differences.

Every time someone brings up the A4, the diesel suggestions start to flow.
LOL Okay the guy needs a head, he can buy a completely new aftermarket one
from Moyer for $450 and be back on the water in, literally hours after
receiving it... OOORRR... he can buy a used diesel for $2500 and replace
that and all the fuel lines and fuel tank and filters and whatever else for
a minimum of another probably $1500 or $2000 in parts and periferals like
what prop, shaft, whatever, and install it all himself in, oh i don't know,
2 or 3 weekends... Then there is all the adjustments and testing another
weekend at least. What is the gain, It's sail boat, isn't the idea to be
sailing and not chugging along under power for days at a time? I mean the
diesel with most certainly add to the value of your boat, but probably no
more than the cost to convert it. The Atomic 4 is a great motor and, in my
opinion, better suited for coastal cruising and day-sailing. I guess if
your going to do some passage making then, yes, the diesel would be a good
decision. Then there is all the rhetoric about unsafe gasoline in your boat
and fuel consumption. Of course there is truth to those statements but, how
many boats do we hear about exploding every year? Fuel consumption? again,
if your passage making, but if you're just using it to get in and out
harbors or to motor home for a few hours when there is no wind, I really
don't see the benefit. You can get gas at far more marinas than diesel
too... Besides, they don't stink and they're quieter than a diesel! End of
rant, Sorry I couldn't stop myself... LOL Go A4!!! Danny!! P.S. Just for
full disclosure, My brand new A4 from Moyer STILL doesn't run the way I
think it should...

OK Joe, same for the Universal M4-30…I got one in my 35 MKII and it
fits well in the space with no apparent mods to what it sits on…it is
also basically a Kubota engine I believe

Nothing is an *exact* drop in, but Beta Marine has IMHO the best
“almost an A4” diesels. They are based on Kubota blocks.
I lucked out and got a very nice A4 that had been rebuilt as a project by an
engineering officer for $1500 on Craigslist. I bought it within about 45
minutes of the ad going up.

If so, I believe the Universal M4-30 is a drop in replacement for the A4 on
a 35 MKII. I know the previous owner of my 35 MKII after several (4)
disappointments with A4 replacement engines or heads took the plunge and so
I ended up getting a 35MKII with a diesel already installed and that little
4 cylinder has lots of power for the boat and runs quiet and smooth as
silk…he also changed to the H5 Autoprop when he installed the
diesel…that’s a really good combo…It does require a
significant expense to do the job, but why not, especially if ones intends
to keep the boat, you never regret having a could auxiliary propulsion
system

I know he's looking for an Atomic 4 but I thought he might find value in
converting to diesel.
