If I buy a used/rebuilt Atomic 4 online and have the yard install it the costs will be similar to just rebuilding the Atomic 4 I currently have...

Thoughts?
No, it should be cheaper. If you find a running, used engine and have your yard install, you can probably get by for 3K-4K. Please see the posting in this forum I made about the A4 for sale in Muskegon, MI for $2,500.

Re: $6,600 to rebuild Atomic 4? replace/rebuild

In my normal polite manner i have to say



I find it hard to believe some of you have pulled a motor out of a sailboat



Cleaned up the 40 year mess



You could not possibly have bought many parts form Moyer as i was into over a 1000 dollars for a much more minor rebuild

And doing a complete tear-down is a bitch with the integrated transmission





And then left the boat in a reasonably professional manner

Re: $6,600 to rebuild Atomic 4? replace/rebuild

Two thumbs up - didn't that feel great when you lit that thing for the first time in that spotless engine compartment?

I'll bet it cost a whole lot less than the 5 figures a diesel swap would have cost as well.

I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.

Re: $6,600 to rebuild Atomic 4? replace/rebuild

Tom, the pricing I quoted is right from MM's site. The OP mentions nothing about replacing the shaft, stuffing box shaft log, repainting the engine bay etc. if so, I could see the cost reflected in more parts and more , a lot more labour.

But let's not overestimate the complexity of an atomic 4.

It's a whole lot simpler than this:

an engine which can be torn down and rebuilt in less than 10 hours. fewer bearings, simpler valve train, half as many heads, no separate cylinders or a split case to align and torque down, etc.

It's 5 o'clock somewhere:

Re: $6,600 to rebuild Atomic 4? replace/rebuild

Moyer gets between 3000 and 6000 + dollars for a rebuild

Now I know your spoiled because you live in a freshwater area BUT I own TWO saltwater A4s and even with the unit in Seafever having been converted to FWC 30 years ago

I can assure you unless you can drill out bolts much faster than me you will not have one apart in 10 days let alone 10 hours because I had to use supreme caution to break as few things as possible to return it to its current state and that was still over about 2000 in parts as I forgot about all the stuff I used from my second motor and did not have to buy

Stuff like rust wiping out the seal area on the output coupling Is a 65 dollar part and it just keeps going up till you hit a pretty big number

If seafevers block had needed a bore job you would have had to drill out ALL 18 studs and a whole bunch of other stuff to get it to the point it could even be put in a boring machine





mucho rust




The donar motor saved me mucho money




The motor mounts that now move ,water pump that pumps and valves SO you can service the impeller without dumping the antifreeze was over 600 dollars alone

Re: $6,600 to rebuild Atomic 4? replace/rebuild

Do you replace the valves or grind the angle on them at a machine shop? I do not know. I assume some intake valves might be good as they have less heat to deal with. Lead has been removed from the gas that acted as a lube for the valves. Is this engine from the 1970s when gas still had lead? Todays valves are made better? Cost of the part vs labor ? Next the head a trip to the machine shop clean, check it for cracks, machine new valve seats and guides so the valve will not wobble and beat out the new seat. This is how I think it might go if it is kind of hard to pull an engine in and out and enjoy a lot of time between major engine work. That is just some points I might think about on the top end. I have not made it to the block and the bottom end. Would they lap the valves and call it good. Price and quality and expectations? Reply asap I would enjoy learning more about inboards. Kind regards ,Lou

Re: $6,600 to rebuild Atomic 4? replace/rebuild

Tom, I get your point.

My point is, unless we get more info from the OP- the condition of the engine currently, is it FWC, what is included in the quote, etc. the numbers don't add up.

Further, it is such a dead simple engine, it shouldn't intimidate the novice. get on the tools, get your hands dirty, become intimate with the beast that bears you, (okay, that didn't come out right) and get it done.

I understand the unique joy of removing oxidized studs from oxidized blocks thanks to salt exposure- welcome to old cars and ontario winters. The A4 does have an advantage- no aluminum or magnesium blocks or heads to really make things frustrating.

It's 5 o'clock somewhere:

Re: $6,600 to rebuild Atomic 4? replace/rebuild

Can I ask what do we mean when we say rebuild. ? Does it mean taking parts to the machine shop? Does it mean running a hand drill hone run up an down the cly walls and lapping the valve seats, new gaskets, bearings and done? How much has to be done to get to get x amount of trouble free hours. Each engine will have its on needs. What I am asking is how much is enough on average? Regards, Lou

Re: $6,600 to rebuild Atomic 4? replace/rebuild

Lou, it's all about the spec. For instance, if the valve seats and guides are worn beyond spec, if the cylinders are beyond spec, if the crank bearings are out of spec, it is going to cost more to rebuild than an engine that hasn't got scored and ovaled cylinders, spun bearings, sloppy valves, etc. A well maintained and babied 2000 hour engine will be a cheaper rebuild than a beat to hell, never maintained 500 hour engine.
