Saving Old Seagulls

Here are some pics to show progress. http://i278.photobucket.com/albums/kk103/synwhistles/002-2.jpg Prop and broken spring come off to reveal just how bent the propellor shaft is! http://i278.photobucket.com/albums/kk103/synwhistles/001-3.jpg And this is what's in the gearbox. http://i278.photobucke...

No. I've been running at 3/4 power out on the open water. No plug problems.
Thanks for the suggestion though.

Thanks for those replies. I can see I'm going to be busy checking them out!

So, changed the head gasket but still only runs for 20 mins. No marks inside the block to indicate problems there. Any more suggestions?

Thanks Chris! A couple of questions that will display my seagull maintenance ignorance; ..The gearbox contents have turned into a sticky brown gel, is there a suitable solvent or is a strip down the best method to clean? ..I wanted to clean the carby, but the float and needle seem to be retained in ...

I gather this is a 102 model, but I can't find the serial numbers. Any suggestions? http://i278.photobucket.com/albums/kk103/synwhistles/newseagull001-1.jpg http://i278.photobucket.com/albums/kk103/synwhistles/newseagull002.jpg http://i278.photobucket.com/albums/kk103/synwhistles/newseagull003-1.jpg...

The steering may be better with the motor forward but I the fumes would be annoying. Side by side I don’t think the speed would be that different the Russell R has a longer waterline may have the edge loaded. At nearly 22’ long the Russell R rows OK, stand up rowing. after the Goolwa Wooden Boat Fe...

Don’t understand why you would want to change either design. Beams are the same; 5'8", but the RR is nearly 2' longer, giving that extra bit of room for a long trip. I'd be using a mix of old and new, Seagulls and a 5hp Tohatsu, so the power available will be more suited to the PC than the RR....

I have been reading the Murray River Boat thread below here and am contemplating building a similar boat myself for a similar trip. Then I keep looking at the Seagull Trunnell plans and wondering about doing a trunnell conversion on the basic Russell R design that they used. I can see value in bring...

So, Riptide out of the way for now and it's back to the Seagull.
I have a head gasket on order, but tell me, does anyone ever make their own?

Here she goes. Don't worry about the purple lines, they are just some sunlight leakage in the lens. http://i278.photobucket.com/albums/kk103/synwhistles/th_011.mp4 I'm still not sure about what to do with the ignition advance. Should I tighten it up so's it does not move around so freely once the mo...

Well, I'm not going to die wondering about this, so into the workshop this morning, disconnect the cooling tube from the head, 4 bolts, a gentle tap with a rubber hammer and she's off. Here's the head. http://i278.photobucket.com/albums/kk103/synwhistles/001-2.jpg Here's the other side of the equati...

http://i278.photobucket.com/albums/kk103/synwhistles/001-1.jpg Flushing the cooling with a silicone nozzle fitted to the hose. A good idea! Good flow all round! Then tried to start it with the prop off and in a tub of water. A couple of kicks and then nothing. Looked at the sparking plug... covered...

That's a Wico-Pacy ignition. There's a 2 cylinder version (2 lots of yours) sitting in a box at my feet waiting for some attention, that came off an Anzani that I'm trying to find a contact breaker for. That's the sort of engineering that reminds me of dour Scotsmen with square fingers. I can pictu...

Somewhat later the same day.... http://i278.photobucket.com/albums/kk103/synwhistles/006.jpg It's a bit untidy, but this is a piece of delrin, drilled and filed internally to fit the flywheel nut and formed externally to fit this socket. (A bigger socket would have been better but nevermind for now....
