Saving Old Seagulls

Has anyone out there ever seen an HSD, I've only ever seen one complete one.

This is a rare one it would be fascinating to see 2 pictures of any that are out there, full length & engine number.

Your forgetting he was using the L all the time, many of the Seagulls during that time were long shaft, liitle boats weren't as plentiful in the 50's & 60's & not many had money for toy boats!

If that week they were only assembling 40 that's all the punches he'd need to hand.

Has any one thought about the gentleman who stamped this engine number? All day long his job comprises testing the motors in the test tank, & providing this featherweight passes the test, it's taken out of the water cleaned off, taken to the bench where the number is stamped, where the number is fou...

Remove the piston & clean the crank & rod with fuel mix, remove all the waxy deposit with a paint brush.

Part of the carb choke shroud.

Don't take it apart until your sure it's necessary, is there any rust or discolouration around the big-end needles or excess play in the big end? Yours looks like it hasn't had a hard life from here, so leave it alone! Oh that wasn't yours it was H-A's. And I don't know if there is anyone in the UK ...

Could it be an earlier one H-A, single water inlet holes, long pinion shaft, but no oil nipples, can't remember if any of the AC's ever ran oil.

I've never seen that style before, though I do have a 20 litre red remote steel tank with enough of a water slide transfer & fuel mix to show that it was sold by Seagull about that time.

Nice find!

Jennings is considered better than Bell even though it's earlier. Or try Motorcycle Tuning two stroke, John Robinson. Two-stroke Tuning, Roy Bacon. The Two Stroke Engine it's design & tuning, K. G.

I've never seen a Minimax that weighted less than 60 lbs, you might get one down to 35 lbs if you use carbon composite but that could be 3000 euro plus, if you did all the work.

See if you can find somebody with one that you can test drive in Holland.

Whose the author of your two stroke book?

Your weigh will also make a difference. Look on the Kiwi sites for a boat called Microgull a shallow V bottomed speed boat with a windscreen, black hull yellow deck, that weighted less than 40 lbs before painting, 6mm ply below waterline 4mm above. The carb has to suit the complete inlet tract! Bria...

Before you start on your Minimax, have a look on the New Zealand Seagull racing web sites , they race in water conditions similar to yours which are very different to the open sea in Bermuda. In NZ only Pirate Pete uses a Minimax & he uses a 5R on the back, but he does post films. Have a look at you...

Check your HC it should have another letter in front of HC.

The piston is too low in the bore to move it far with the grease nipple method.

Check the jet in the 418, if it's fitted with a 100 it's been removed from a Curlew where the 418 was the standard carb.

But if it's wearing a 110 jet, there's a factory fit possibility.
