Default The camshaft crapshoot

OK, it is not an aircraft engine, just an interesting observation. I bought this engine 15 years ago from a fellow that had it in his garage for 20 years with the cylinders full of oil. It is a flathead 4 cylinder sailboat engine with a design that dates to 1949. This is the early model that was built before 1969, how much before I have not researched the number. I opened it a couple months ago to check it out as a replacement for the tired engine in our boat. I was surprised at the condition and I would guess it only has a couple hundred hours on it. The rings were all stuck, but a slow fix. We put 11 hours on it last week on a 3 day trip, ( the wind never blows the right way for me), and it runs very strong.

Good on you Will. All I needed was a rebuilt transmission that the marina had fall, winter, and spring to do. SO, after waiting for the Mississippi to flood twice in that time span, snow to come and go, the core being rejected, spending four times more than budgeted, she was scheduled to be launched yesterday. NOT; due to the brakes failed on the launch vehicle so maybe next week!!!

I swore off all boats... I traded a Hatteras for a Stearman and recently told the Stearman past owner, he should do the same when he called me with problems on the boat. He wholeheartedly agrees. ESEB = Enjoy Someone Else's Boat, a motto to live by.

"Hole in the water you pour $ into." There should be a similar saying regarding airplanes. The only one I recall was what a friend told me when I purchase a T6 project many years ago, "Most effective way to turn $ into noise yet invented by man."

I usually describe the plane as a hole in the sky you pour money into.

Get a seadoo.. fun , cheap and reliable. Used to have a bigger boat and what a pain. Seadoo is trivial to trailer, fits in my garage on a dolly, we can wake and swim off it and even take it on little road trips to see different lakes/rivers etc. Think I spent 9k on it 6 years ago and nothing since then. less gass to!

Castleman, is that a Continental flathead? I have one on my 50's era Lincoln Pipeliner. Has a fairbanks/morse magneto for ignition.

Have a Lincoln S4-200 with Continental and mag. Brand new 66. Belonged to my bosses dad who had a welding business. Bought a 66 Dodge 200 truck to put it on; his dad only took it off twice. I removed the welder a couple of years ago, but use it occasionally. Tried to move the truck last week; brakes frozen. Grrrr.
Lycoming sharing lobes on opposite cylinders don't help. Those lobes never get a break.

No, it is an Atomic 4. Design from the late 40's hence Atomic. It is a flat head with the planetary/disk behind it that uses the same oil, oil pan (cast). Magneto was an option in the old days. The reverse gear will last 2 engines, very reliable. I had an online biz selling parts 10 years ago, Nuclear Engine. which did not make any money but I could work on boats 60 hrs a week if I wanted to but did not. 350# and about 25 hp. Runs very smooth. Mine is bolted direct to the fibreglass, no rubber, and when it is at idle you can only hear a little exhaust. They were killed in the early 80's by the kabota tractor engine conversions. Diesel seems to be a testrone thing. Everyone would parrot the fire hazard thing but I would ask them if they have propane heat/cook. I adapted a mallory dist and put electronic ignition in it. In 14 years hardly touched the engine except for the carb cleanout a couple times and the normal exhaust elbow replacement. Now let me tell you about my recent conditional inspection.......

I've heard of these little engines but not being a blow boater I've never encountered one. Sailing on the Mississippi is a study in contradiction. Current is never ceasing and crabbing in to the wind can be short lived due to the width of the river. There are quite a few sail boats up on Lake Pepin due to the river being several miles wide there but we don't see too many down here where the river runs less than a mile wide.

Ha Ha! The mighty "Big Muddy" has flooded twice in the last 7 months, so it looks a lot like Seattle around here most days!
