hey slug.......without pinching your Seagull thread on old engines......
About 60 years ago I remember my dad taking my elder brother & I out fishing on a lake on the south coast of NSW in OZ.....[Narooma?]
From memory it was about a 15ft clinker hull with a single lunger inboard petrol engine with a flat leather strap around the flywheel to get it going
Steering was via a tiller
I distinctly remember being concerned about the water in the bilge under the [boum boum]
............. it was raining & I wanted to go back to shore.....
....
At the same little boat yard were the same 15ft clinkers with what I believe were Seagull single cylinder [put put] outboards.......Derek
