Wooden boat with Olympia 3-3.5hp 1930

- My boat. The engine is an Olympia, manufactured in Vaasa, Finland, in the thirties. It's a single cylinder, sidevalve, four stroke, with 75mm bore and 110mm stroke. Peak power is at about 1000 rpm. The flywheel is very heavy. It has a handle which is used for crank starting. When the engine is running, the handle can be folded into a slot in the flywheel, by placing a shoe, or similar, close to the flywheel.
I have taken the engine completely apart to restore it. Spare parts are hard/impossible to find these days. So you have to make them yourself, or be creative with using parts from different engines. After a lot of searching, I found a piston with about the same dimensions as the stock piston. It's from a four cylinder Fiat from the seventies. The diameter is a few mm larger than stock, so the cylinder has been bored/honed to the right piston clearance. The piston top has been milled a few mm to get the right height/compression ratio. (About 6:1 in these engines). The connecting rod bronze bearing has been replaced and honed to fit the new piston pin. Shims in the crankshaft bearings has been changed to get the right bearing clearance. After the restoration, the engine is mechanically almost silent, and runs really smooth.
In the video, the engine stops just as I'm about to put it in gear, simply because I forgot to turn on the fuel valve...=)

Probably says something about me that I would rather cruise around in your wooden boat than the white speedboat that was next to it. :)
That is one of my favorite boats , and no better place to cruise in it.
You did a great job with this old engine!
That looks very peaceful. I'm surprised at how easily it travels on a motor with such low power.
Torque!
love this stuff, thanks for sharing, super cool
That is very impressive ! Scoots right along . Well done
Good to see it still in service.
Nice job Bjorn! This is great!
This is what I wanted to see, one of these motors in use on a boat. Thank you.
Very quiet ! Excellent video
Charming boat and engine....classics😁😎
Built to last. Very nice rig.
Wonderful old engine, i bet its been running for years and years like that and i was quite surprised to see how fast it pushes along, i presume that its seawater cooled so little chance of it overheating, really made to,last. Great video.

I love this boat!!!
This engine is heritage of my hometown 🙂
Har haft encylindrig Wickström min far hade 16 hk Olympia i stora båten. Man fick sota dem emellanåt. Härligt.
Scooting right along ! Lovely.
Чё за речька ford edge впадает
Nice relaxing video :-)
Very cool. I once had a similar combination. Slighty larger boat and an Andros k-11 engine.
MMMMM! Well done!
Good torque at low rpm!
What a thing of beauty
Wow thanks for sharing. I think the boat and motor are beautiful together and have been made aware of these old motors now and have my eyes and ears open along the New England coast for something even to restore to running. Would love to find something with a sail maybe a knockdown?
Very nice!
Make and Break engine. Good job on restoration. Thanks for posting, East coast Canada.
fwiw, this is a 4-stroke engine not a "make and break"
@@lantrick Thanks, I thought it might be like the Acadia and Atlantic marine engines of the past,used by inshore fishers.
@@guffylips976 I happen to LOVE. Hit and miss (make/break) engines.
Thank you
Would like to see closeup videos of engine when running idle in dock
Isso e um motor do tempo da arca de Noé...
Brilliant 👍
amazing - from the time when people had more class - and weren't in such a hurry! :)
Interesting how similar are the Albin motors from 10-15 years later..definitely more refined but this Olympia is impressive
Awesome!
Det påminner om gamla tider i Hangö by, mvh Östen 80+ 👍🇫🇮
goes great
Very nice,but...
You forgot to turn on the oiler...
The lever should be vertical to feed oil. It would be a shame to ruin that engine because of a simple oversight. You did fill it though... :) !
I know =) I noticed it when I watched the video. I rarely forget it, but it happens from time to time, I can admit. There are lots of knobs to turn on this motor, which is one of the reasons I enjoy using it. =)
Nice!
Beautiful job! Is this considered a dory style boat?
Very nice! where to hurry
❤️ this!
Nice engine, well done on saving it.
Did you finally remember to turn the drip oiler on ;)
This engine doesnt nesseserily need the drip oiler. Its only purpose is to add oli to crankcase when its beeing burned away. When people use the oiler too much the oil level will start to rise.
Nice Diesel engine sound,I guess spark plug is just a decoration 😅
Wow. Still run today
Beautiful boat with a classic rebuilt engine! Do you fish with this boat?
Thanks! I mainly use it for transportation. I'm not much of a fisherman! But I sometimes fish with nets from a smaller rowing boat.
How long is your boat, and how many knots? I love the beautiful job you did.
Hi! It is about 15 feet long, and speed is 4-5 knots. Thanks!
She’s not pretty, she’s not comfortable, she’s not fast. But she is a perfect timeless old chugger. A good sounding slow turning one Luger. Just right for a putt around the bay. I bet it’s a very satisfying ride, especially with that old motor you’ve kept alive by shear grit and determination. She is a nicely easy driven boat. Moves nicely through the water and looks to be a pretty solid little boat.
It was interesting to watch your start routine, and I was surprised at how easy it started!
What do you use for a transmission and do you have forward and reverse?
Does that little engine make enough heat to take the chill off while your cruising?
What kind of boat is it like if I wanted to find plans what would i search for?
-fin träbåt har du. Här i Vasa"s Sjömuseet finns många såna urgamla motorer.
That is the first time that I have gotten sea sick in my living room.

Will the boat remain straight if you release the rudder?
No if I release the rudder the boat will turn to starboard because of spin of the propeller. But by leaning the boat to starboard, I am able to balance that force. So that's what I'm doing in the video when I'm walking to the middle of the boat. I think this effect happens because the tiller is long and heavy, so when I'm leaning to starboard, gravity pulls the tiller to starboard, which creates enough force to keep her straight. =)
Komea vene ja kone. lataa sisää videoita näistä!
I will need how wide the beam is, how long is and how much it weighs. Horsepower. I’ve made friends with the head engineer at Acme and he will tell me what size prop you need, possibly I can make one out of steel for you
Finns det någonstans att få tag på "tändmagneter"? Jag tar emot tips. Hälsningar Stig Österberg, Dalsbruk, Finland.
What size is your prop and what pitch is it , that would really help me out as I am building a boat similar to yours out of steel
My propeller is not the right size I think. It easily starts to slip/cavitate a lot, which means it spins freely, and isn't producing any drive. Then I must release the throttle, and apply it carefully again when the prop grips. This usually happens at less than half throttle, so I have never used more than that. I usually run it at 1/4 throttle, which is enough to reach hullspeed (about 4.5 knots). Prop is 13.5 inches diameter and 9.5 inches pitch.
It's a 2-blade propeller. Do you have a similar boat? whats the dimensions of your propeller?
@@bjornnyman6891 sounds like your gearbox might be slipping. It can be easilly adjusted.
@@galax650, that is very interesting information! I always assumed it was the propeller slipping. I have to look into that. A screw which needs adjusting?
@@bjornnyman6891 Yes, open the metal plate on top on the gear. Then when inspecting the gear drum there is one bolt that needs to be losened. Then turn the gear to tighten the clutch pack. Just a little adjustmeant is nessassary. If you tighten the gearpack too much its really hard to put it in gear, and it could be damaged.
an engine with character, hey?
it is quite fast for being only 3,5 hp
Класс )
My prop is 13” dia. 11 1/2” pitch. It is three blade. It is supposed to be for a full displacement hull, And the hull is 21 feet with a 20 hp gasoline engine. The parameters I gave the prop what is for a21 ft Full displacement hull, With a hull speed of 12 kn for cruising and a 2 1/2 to 1 reduction from the motor. The weight of the hull is 1600 pounds, or 1600 pounds displacement. I making a very similar to your boat on RUclips and it will be made out of steel. I will let you know when I launch the RUclips channel. The name of the company that made this product is acme. I just happen to find it at a swap meet for $30. When I called up the company to see what it was for they asked me what it was going on and I told them and it just happened to be the right one.
Mitkä ovat potkurin mitat?
I have translated your question, since I'm native Swedish, so I don't know the Finnish language. (But I have my boat and some family in Finland). The dimension on my propeller might be wrong. See my other answer from today about slip/cavitation. Dimensions are 13.5 inches diameter, 9.5 inches pitch. Do you have a similar boat? whats the dimensions of your propeller?
starts easily, where is this
FINLAND
Is that an Albin engine?
Albin made similar engines, but this engine is an Olympia. Albin was manufactured in Sweden, and Olympia was manufactured in a Swedish speaking region of Finland.
Are you sure that's not a Chrysler boat motor mine would do the same thing as soon as you would push off it would stall out
=) not a Chrysler! It stopped that time just because I forgot to turn on the fuel valve =) I can't say it's the most reliable engine at low revs, but I'm usually able to keep it running. It often needs some adjustments on the fuel mix knob depending on temperature of the engine and engine speed/load and so on. So if I have leaned it out when out to sea to prevent soot/carbon buildup, I usually have to set it a bit richer to prevent it from stalling when slowing down near the dock. Another thing is the valve for the water cooling of the exhausts. If I leave the water valve open at low revs it will eventually push water into the cylinder and stall the engine due to a drop of water bridging the spark plug gap. =)
If you give me the size of your boat and your estimated weight and horsepower I can contact me and talk to the head engineer and he will tell me what size prop you need
