Saving Old Seagulls

What's the engine number of your silver century, & are you just replacing a faulty CDI?

Glad to see you've still got a pulse Bruce!

If you'd tried your original motor on your boat you could have measured the revs & speed, if you repeated the same test with the worked on motor, carrying the same load on the same hull, if the revs & speed have increased then logically power output also has.

That's an SD 110 Hugo, It doesn't use the standard century cylinder as stated, you can't see on the pictures but has a cast ally inlet manifold fixed to the flat side of the cylinder , if I remember right they also had a goldey brown 418 carb (ally float bowl) with a choke built into the throttle ...

I've just been informed that over 50 boats have signed up for The Bermuda RISR 2025, I'm sorry I won't be there this year.

Hope the Weather's good for them this year & the younger generation show the old timers how it should be done!

My Best Wishes !!

Your throttle cable is passing through the hole in the casting on the tiller arm base, this will damage the cable beyond repair!

That might be your problem.

Check what your plug gap is supposed to be, 30 thou is only used on the white Wypac CDI ignition.

Yes it does.
You'll notice the top screw has a domed end, that's fits in the dimple in the pinion bush & holds it in place at the correct height & keeps the pinion gear correctly meshed with the crown wheel on the prop shaft.

Lay your Seagull down on the ground to see which is the most stable position that will cause the least damage!

I hate to say this but "I hope all you Kiwis have a great Easter on the Waikato!" the thing that's causing me the most distress is, I won't be there with you showing you how a Pomme would do it!

Have a great weekend gentlemen!

Looks like I made a mistake on the date I should have said 37, sorry.

No prop shaft oil seal ,only Bronze bush with the prop shaft through the worn hole in the middle.

The oil that was used in the Wartime & pre War gear boxes was approximately SAE 450 a viscosity that no longer seems to be easily available.

It looks like the prop shaft/bearing is losing quite a lot of lubricant so there could be either badly worn bearings or too thin gearbox lubricant.

I spoke to Chris who will PM you his phone number, give him a call any evening, looking at your pictures your going to be busy.

Good luck Charles

The local man to talk to for you would be Chris Croul who lives in Beach Haven, not too far for you, his phone number I will PM to you when I've dug it out.
Please don't try to start with the drill again It doesn't do them any good when they're over 80 years old.
