Saving Old Seagulls

The Owners Handbook says "with the exhaust outlet only an inch or so below the surface" but you do need to ensure that the water pump is submerged. So more like the "or so" than "an inch" IMHO. So long as the pump is deep enough to pump cooling water its not critical. M...

If you have a good spark the you are half way home.

If you have already cleaned the carb make sure that when you reassembled it that the centerpiece is fitted so that the little retaining screw is located in the slot in the shoulder not in the round hole.

I purchased a 1973 forty plus mark 2 FP218hh3 last year and am having trouble starting/running it. As it had not been used in many years I initially pulled the flywheel and cyllinder head and verrified that there was no internal corrosion or blockage. After cleaning and setting the points and thoro...

Caustic soda granuals. Tip a fair amount in the tank. Add water till half full. And give it a good shake. Leave it sit for a while. And tip it out and flush. You may have to do this a few times until its all clean inside. The fuel tank will get very hot to handle so wear some gloves. cannot comment...

A '75 engine could be converted to run on a 25:1 fuel mix. Details on the SOS website.
They still tend to drop some black oil but not quite so much. I have converted both of mine ( '73 40+ and '74 Featherweight)

As said the copper coloration is not due to the plating or deposition of copper but is due to the copper remaining when the alloying zinc has been removed. Its called dezincification and can eventually affect brass quite deeply so as to weaken it to the point of failure. It is why ordinary brass is ...

M9O in both my Seagulls

R8J in the lawnmower , Villiers Mk 2 Midget.( should be M7J according to the parts list.)

M8J is listed for the Mk 3 Midget

Any idea what the differences are?

. . Some info to explain the meaning of the API rating and the SAE viscosity grading: What does API GL mean? API stands for American Petroleum Industry and GL stands for Gear Lubricant, see below for their definitions: API GL-1 Straight mineral oil API GL-2 Mild EP for worm gears API GL-3 Mild EP fo...

Looks like the carb is tilted. That maybe why its leaking fuel a bit. It should be upright

You will find links to exploded digrams of the carbs on the SOS website in the FAQs section http://www.saving-old-seagulls.co.uk/faq/faq.htm You'll identify the choke flap from the relevant diagram no bother. From what you say about the "carb needle" it sounds like a Villers carb but I tho...

Looks OK to me. 2 stroke plugs always seem to be black and oily on anything running a more oily fuel mix than 50:1 Do you have problem you are trying to solve? No need to resize the pics. Click the picture in the post then click the enlarged picture and you get the full 4320x 3240 image ... that mak...

I use a 1974 Feather weight on my little (8ft) plywood dinghy I have converted it to 25:1 mixture and usually use a TCW3 oil However to get it to run without 4 stroking the whole time I have had to screw the needle adjustment down to about 3 turns "below flush" Checked all aspects of the c...

This what an 8 COM plug looks like when new. It has an 18mm diameter thread I expect the plugs in your Yamaha were 14mm

Yes carrying handle.

It then needs two people to carry it so pretty useless for smaller models that can normally be carried in one hand. Useful perhaps for the heavier ones... provided you have the second person available

Yes you must study the Tech specs very carefully if you are considering an electric outboard. Probably the most advanced ( and expensive ??) on the European market are the Torqeedo models http://www.torqeedo.com/uk/products-2 which range from a light weight model with 33lbs static thrust from only 1...
