|Help needed about Stuart turner Engines
|Posted on Wednesday, July 23, 2003 - 08:06 am: ||
I belong to a vintage engine restorers club in Auckland, New Zealand called V.E.R.A (Vintage Engine Restorers of Auckland) a while ago i aquired a single cylinder Stuart marine engine, which i thought to be a P5, having also recieved 2 unwanted twin cylinder p55's i thought i had sort of "the set". With the engines came a 30 page handbook on the p55 and p5 engines. I have had the p5 running, but while pulling it apart for a full restoration, i found that there was a large crack running through the water jacket into the lower half of the cylinder. It looked to be unrepearable at the moment without having to spend alot of money on it because it has a piece of the cylinder actually missing. So i put this engine aside and advertised that i was looking for another one so i could hopefully make two out of the one. I recieved another single cylinder p5 engine. This one actually has a badge on it saying it is a p5 model. I wanted to know if you could tell me what the other one is please. These are the following details on both of them.
The first supposed "P5":
Has no name badge on it, but is definetly a stuart. It has a 2 1/8 inch bore (or 55mm). The water pump is run from the side of the crank case and moves on 45 degree angle approx. It has the magneto inside the flywheel, similar to a Villiars engine.
The second supposed "P5":
Stuart Turner Ltd
Is a larger engine to the first, larger, more flat flywheel. It had the magneto running either geared or chained off the crankshaft (enclosed) and the pump run off the same gear, but opposite to the magneto.
I am unable to get the bore and stroke of the second Stuart as it is siezed at the moment and i am having troubles getting the head off it. If you could help me with this, it would be muchly appretiated. and if you would like further information about the two p55's, maybe the serial numbers etc i will get them for you.
thanks for any help

Firstly on your engine numbers I have some approximate manufacture dates as follows:
P5VC16423 - I haven't got this one on my list - can you check it again?
P55: P55MC27722 - this falls in the range of engines built between Oct 1949 to May 1957. 2,600 were made over the 7.5 years so yours would likely have been made in about 1952.
P66: P66D22B777 - this falls between May 1969 and Jan 1976 with with 894 built over that 7 year period so yours would likley have been made almost certainly during 1975.
In respect of the first supposed "P5" you state that it "Has no name badge on it, but is definetly a stuart. It has a 2 1/8 inch bore (or 55mm). The water pump is run from the side of the crank case and moves on 45 degree angle approx. It has the magneto inside the flywheel, similar to a Villiars engine"
This is an R3 not a P5 - based on the bore size, the angle of the water pump and the location of the magneto. The R3 is 1.5HP and both the bore and stroke are the same. You will find that the exhaust outlet is also different to the "second" genuine P5.
In respect of the second supposed "P5", this is a typical P5.
I responded to Aaron via personal email about the Australian Heritage Fleet engine area in Sydney providing him with a lot of reference material at a small cost (we get no goverment funding). Our address is

I'm trying to locate a Stuart Turner P55 which I owned about 30 years ago. I know this is a long shot but I have faith in the Internet.
The engine is a P55 which I salvaged. It came out of a wooden boat that sank after launching. The seas were rough and I watched the keen but niave "sailors' attempting the lauch from Burns Beach in Western Australia. The boat was lifted up and forward by the waves and holed on the winch post of the trailer. The waves then lifted it back off and took it far enough away from the trailer to allow it to sink. The "sailors" almost immediately gave it up and I asked them their intentions. They said I could have it and gave me the address of the -real- owner who they were going to return the crank handle and magneto to.
Anyway, I contacted the owner who agreed that as I appeared rightfully to be in posession of the engine, I might as well have the crank handle and magneto.
I cleaned the engine and got it running just fine. Having not long been married and saving to buy a house I reluctantly sold the P55 from our rented home in Nedlands W.A., around 1970/71.
If the current owner reads this, It would be great to hear from them.
How did I salvage the P55? - well, that's another short story.

I had 5 Stuart P55s shipped from Perth in WA last year and am currently restoring 3 of them. The other two were fire damaged and will only yield some parts. I also have one in a boat and have restored a P5. You could call me a keen Stuart enthusiast.
I will contact you in a few days with further information after I contact my friend in Perth who organised it - a couple were his and he sourced the other one. He has another and knows about a couple more.
Would you have the engine number???? - a long shot.
Do you have any Stuart info or the bronze handle. I could use another one or two bronze gear change handles. Also, Bob Price in the US is also after one.

I am looking forsomebody in Perth,Western Australia who can help me with info,etc to get a stuart turner P66 up and running. Motor is complete and ready to go. Timing is perfect,spark is strong but refuses to run.Any help would be very much appreciated.

Dave....if your timing is ok then we can eliminate that.Your magneto may be sparking but what about when the plug is under compression?
What about the plug no doubt you have a new one.
If all that is ok then think about compression and in particular ,crankcase compression. Check your seals ,check the clearance of the centre bush ,if it is more than .008''replace it.
One way to check if all other settings are correct and overcome the lack of compression is to rig up a starter motor ,an electric motor driving the flywheel rim via a vee belt is enough for this . Spinning it at speed will overcome the compression prob [ unless it is really bad].
There are other things to look at ,all basic but sometimes therein lies the problem . These can be dirty carb ,wrong fuel mix,choked exhaust or flooded crankcase.
It can be frustrating but persevere.

I have a P55MEA which I have now got new points and coils for. Does anyone have info with respect to setting the timing up on this engine.
Any info gratefully received.

Re timing on the P55. On the flywheel is marked "TDC" (top dead centre) for each piston and another mark "M" about 2 inches or a little less before TDC.
Withdraw the magneto, loosen the bolt on the magneto coupling disc and also loosen the coupling from its tapered shaft. Replace the magneto and time it for when "M" for one piston, with No 1 near the flywheel being the easiest, is on top (12 o'clock position). Turn the contact breaker until the points for that piston are just breaking. Withdraw the magneto and tighten the magneto drive shaft coupling bolt.
If you have an impulse magneto then follow the same steps until you initially replace the magneto then rotate the magneto spindle anti-clockwise until the points are closed, then reverse until they are beginning to separate. Without disturbing anything, withdraw the magneto and tighten the bolt on the coupling drive shaft.
Check the timing to ensure that the magneto coupling disc has not slipped. Then the magneto can be permanently fixed in place.
The above extract is in the Engine Manual.
