Chris, You can download the instruction book for the P55M from www.semidiesel.com/onl.html It takes a long time to download and you need Acrobat Reader to read it but it's all there.

I also am in the process of restoring a P55. I have found Dave with Fairways Marine in the UK to be a wealth of knowledge and parts. Fortunately, my engine is complete and I even managed to purchase the boat with it. The engine had been removed from the boat about 12 years ago and put into storage. The boat is complete, right down to the original sails, masts, sculling oar and even the boat hook. The wood is very sound and I will have to replace only about 4 or 5 of the hull planks. The interior of the boat was stripped right down to the ribs. Lots of fun to do and I am looking forward to sailing it this summer. BTW Peter...you never got back to me with a price on the P5. I would love to build one of these boats from the keel up.

I'm seeking information for a friend (no access to internet) whose well advanced on his P55 restoration. He's asking whether there is a gasket between the gearbox and the block?

I've located a booklet on the semidiesel database of engine manuals but it hasn't got sufficient detail. I'm chasing a technical manual.

Also, I saw a message from someone about the fuel mix being important. Can someone tell me the correct mix as it wasn't in the booklet either?

I've located a Solex carburetter booklet on http://www.oldengine.org

Also, see a story on restoration of a P55ME by Andrew Hollis at http://gosh.ex.ac.uk/~se99aph/P55ME.html - thanks to Chris G for this info.

My P55 project to start shortly.

thanks

Tim @ Sydney, Australia

Hey, obviously no one checked that I gave you a vague reference to the Solex carburetter booklet - here is the link to the page on Peter and Rita Forbes' website found via the link on the oldengine.org.com website http://www.oldengine.org/members/diesel/solex1.htm

my apologies

I've recently acquired a Stuart Turner Marine Engine P5MX. I'm having great difficulty in starting the engine. Magneto is fine, sparking at correct point near TDC, carb/air intake/jet appears to be working, but it won't two-stroke.

Any suggestions would be gratefully received.

Many thanks,
Ian.

Ian,

I'm still learning about my P55 so do not venture advice but listen to those with more experience.

In the discussion thread "Thinking of Seelling a Stuart Turner P55" Russell Ward posted a message on 9 June 2002 offering some good advice. However for some reason his message has dropped off.

Fortunately, I quote the following points from my hard copy:

1. "Nothing to go wrong if set up right to start with ie you need plently of compression and a good mag"

2. "you need the oil/pertol mix as per the manufacturers specs" which according to the handbook is 20cc of oil to 1 litre of petrol or in other words 20:1

Hope this helps and thanks to Russell for his advice.

Sounds like to rich a fuel air mixture. Close the needle valve up a little until it two strokes.

Ian .......the P5 series has the Stuart type carb. It is a good one as it has an adjustable mixture ie the knurled screw in air intake . This has the little anti vibration tab on it . The adjustment is achieved by screwing in the cap ,this is a cone ......screw in = richer mixture . Screw out = leaner mixture . Like all these Stuart engines they are easy to start as long as they have good compression . If they dont then put a few drops of oil in the spark plug hole .
Hope this helps .

Tim ......there is a gasket between the gear box and the engine block , nothing fancy just so long as it stops any oil leaks . Thickness is not critical you can adjust the cone centering quite easly . Those bloody little hex head cap screws are a bit difficult to get torqued up but you dont see many oil leak problems .

I have a Stuart P55 with a Solex carby. I am having severe flooding on full throttle. Fuel bubbles from the main jet and the engine drowns in petrol,& has no power. I need to either restrict the fuel flow with a smaller jet, (a 100 is fitted now) or add more air to the throttle body to restrict suction on the jet. Does any one have any suggestions?

Just a correction to an old post by Tim Mulvey:

The carburettor handbook reference was changed in a big reorganisation of our site, the new reference would be:

I have fitted a smaller p6 Stuart Turner engine into my 23ft Buchanan Spartan but am still using the larger propellor that was used on the larger p55 engine with reduction gear box -I find that any revs over a third have no effect- -can anyone advise me what type and size prop I need to obtain full power as little as it is
thanks Ken Gregory

Stuart Stern Gear specs chart found in the Stuart Marine Engine Catalogue shows that reduction model ie "R" in the model type eg P55MR uses a 14 inch diameter propellor compared with a 12 inch version for the non-reduction gearboxes.

The reduction box turns the propellor at half the revolutions of the direct gearbox hence it has to be a larger diameter to move the same amount of water. I'm no expert on the dynamics but can recommend an article that appeared in the (English) Practical Boat Owner magazine No. 6 June 1967. It's quite technical but not needed if Stuart owners use refer to the chart in the catalogue as mentioned earlier.

The Stuart branded propellors have "Stuart" and the propellor size stamped into the boss of the propellor. My boat has a direct drive gearbox and uses an 8x12 Stuart propellor ie 8 inch pitch and 12 inch diameter.

PS: I didn't see where the pitch is mentioned in the catalogue but presume 8 inch pitch is standard.
