Saving Old Seagulls

Thanks,

Is it just my computer?
All the photos have gone. When I click on the blocks, it says image no longer available.

John, The flywheel itself is totally enclosed. There is a small blue plastic disc in the top of the part of the flywheel where the rope starter is wound. The tank is steel, oblong, and covered in what seems to be blue plastic. The engine is in very good condition and runs well. It was an executor sa...

My 40 minus has the number
EF 195 BB3
The engine identifier says made in 1973.
BUT directly underneath, it says that EF engines were made in the 1980's
Confused.

Thanks Adrian.
I have a 2.4 meter at the moment but find it too small.

Could you please tell what boat you have, size and type of floor?
Mike

What I have difficulty with is that the 40 power head coupled to a 40 minus leg and propeller will produce (allegedly) 45 lbs. thrust.
Swap the same power head onto a 40 plus leg and the power apparently climbs to 55 lbs.

Is that why the featherweight is only quoted at 45lbs, but the same engine with 40 plus leg is quoted at 55lbs?

On the weekend I tested a 1983 Mariner 2 hp on flat water in a cutting off the Thames.
It developed a bollard pull of 50 lbs.

Thanks Charles. I was wrongly advised and bought 90 oil, I have 140 on order. My guess is that the 'leak' was unburnt oil from the combustion chamber gathered in the exhaust. I have now used the engine quite a bit and can say that I am a convert. Seagulls obviously have their draw backs, mainly leak...

Charles, Yes my new top washer is some sort of fibre, but as I say, it is not thick enough. I don't know whether my fuel cap is defective, but it seems fairly new. If you take the washer off and tighten the screw, it does not go all the way down leaving a 1.3mm gap. Because the washer is only 1.3 mm...

Did you look at the plug?
I would not be surprised if it was white.
I had a similar situation with a Mariner 2hp. Turned out that the air screw on top of the tank cap was getting obstructed.

Charles , I did, as explained above, the new washer etc. could not work satisfactorily

Phil, That is very kind of you but no need. The rubber washer is still steeping in petrol with no ill effect so far. As for Sikaflex, it is a polyurethane mastic and is so effective that they say 'It will stick ice to water!' It does not dissolve in anything, so when building campervans etc. if you ...

Phil,
I am testing this rubber washer, so far, so good but I suspect that it will not hold up long term.
Plan B is to make a sheet of 2mm thick Sikoflex between two oiled sheets of glass and use that!
