Saving Old Seagulls

Hi as the title says what is the biggest Seagull HP made ?? Oh as an aside Shirley "dribbles" oily residue down her exhaust shaft..is she just a dirty girl or or a well used girl ??(I am ex RN so am ready for the bad news that she is well worn!!)

Apart from the very early Marston Twin, probably the most powerful Seagull is the very late (and not very Seagull) "Seagull Sport" which generates enthusiasm in the Seagull racing fraternity. As to the actual HP, the other Charles is far better placed than myself to provide figures. They will be rather lower, I fear, than expected.

Dribbling is quite normal...

So what is the max HP around ??Just wondering so as to power my 14ft Mayland. ?

charles as a newbie to seagull specs, marston twin you now have my attention i honestly thought they were single pot
boy i have a lot to learn. new to the history of seagull, its very intresting. coventry victory is also pricking my attention hmmm

The thing is with the Seagulls, not everything is known about them, even the unknown ones.
