Hi I should introduce myself, I live on Vancouver Island British Columbia Canada, Have built a 13' wooden steam powerd boat, presently have a 12' clinker rowboat, interests are mostly mechanical, consequently I am starting this thread

I am going on failing memory, but I seen to recall the the Lunenberg Foundry in Nova Scotia made the Atlantic series of engines from the late teens to 1995 when they closed their foundry.
Their first 2 cyl 14hp had the crankcase cast so the crankshaft slid in from the rear. Here is where the memory gets cloudy, I believe around 1938 they changed the crankcase so now it was split horizontally. My engine is of the newer style. I have yet to find it's year of manufacture.
This engine came to me in a 20ft steel lifeboat, story is the life boat came off a freighter that hauled fruit from SA to eastern Canada. When and how it came to recieve the Atlantic I do not know. About 25 years ago this boat was shipped to Vancouver B.C. It then ended up in Nanaimo on Vancouver Island and was used locally as a dive boat. Too many years of salt water cooling ended it's usefull days. It was left over several winters which were cold enough to freeze the water jackets. I acquired the engine as a total wreak. Both cylinders plus the manifold were frost split into many pieces, I thought i could braze the bits back together but found the rear cyl was corroded right through into the combustion chamber.
By putting a grease fitting into the tapping in the top of the cyl I could pump the cyl full and push the piston out (front cyl) it was stuck but finally moved. Rear cyl was siezed too but the grease started coming out through the cracked water jacket so I know it's perforated, I'll have to cut the cyl off the piston to get the rod out to reuse it.
After several years of procrastination, I contacted the Lunenberg foundry, as luck would have it, they still had 2 new machined cylinders, 2 finished pistons, a unmachined manifold, and enough rings to fit both pistons. Price was not cheap but what are the chances of finding good used parts? Plus these were the last of their stock.
So it's Nov 18th 2010, I will recieve the parts sometime in Jan of 2011
Time to start cleaning the bits and getting the bottom end ready. I will have to find a coil for the ign system.
20 million items on Ebay but no primary coils. Guess I'll have to make one.

Making primary ign coil. 2 discs of 3/4" ply 3" in diameter cut with a hole saw. For the iron core I used #16 gas welding rod which comes in 3' lengths, by bundling about 35 pieces together with elec tape and then inserting this into apiece of plastic tubing I was able to cut the bundle into 6" lengths using an angle grinder and thin cutoff grinding wheel. Cut enough to make a round core 1 1/2" in diameter. This I wrapped tightly with electrical tape leaving approx 3/16" of the core untaped at each end. I used a 1 1/2" speed bore bit to counter sink each piece of ply then epoxied these onto each end of the core. I mixed micro balloons into the cold cure epoxy to thicken it, but sawdust would have worked too.
2 days for the glue to set. One ply disc was drilled with 3/16" holes to pass the wires through,and I then patiently wound # 16 automotive electrical wire around the core. It takes about 300 lineal feet of wire to put approx 400 turns around the core. Wire was passed through the drilled hole next to the core (other hole was drilled near rim). When the windings were finished this end was passed through the rim hole. I then bound the whole winding with electrical tape. 2 terminals were epoxied to the end cap and the wires soldered to them.
This construct was reccommended to me by Chris Hawse and I must say it produces a very hot spark.
Now all I have to do is restore the engine.

Wil post pix of Atlantic later as I lost all that were in the puter, side note , almost bald from pulling hair trying to get pix onto page.

these pix are from the Mystic Seaport Museum my engine is almost Identical except that this is an 8hp twin.

I'd be interested in seeking pics and some info on your steamer, as well. 13' is pretty small for a steam launch, so your power plant ought to be interesting.

Lost all pix will take more in the next couple of days

10 cu ft boiler, single cyl double acting engine 2 X 2 1/2 12X20 3 blade, Becker rudder, has a moving rear edge that compounds the turning force. Red Cedar on oak makes about 3.5 mph on 90psi. Engine and boiler were built in Victoria B.C. Canada about 1976 Cliff Blackstaffe built the engine , unfortunatly he is deceased now. made approx 25 of these in his lifetime, 2 are in Nanaimo 1 is in a town south of here .
I added pix to original post.

Hold on to that little Blackstaff engine! Now that he's gone, I expect his engines are going to increase in value. He was quite the legend among the steamers. Nice little plant, there.
