This is the big boy, a British Seagull, Silver Century Plus long shaft, built in April of 1976. Not positive how to confirm hp, but I'm assuming the large prop would dictate more hp. It hasn't run in several years but stored inside, so I poured a little mix fuel down the carb, turned it over by hand several times, and it fired up the first pull. The clutch engaged, and disengaged perfectly. I bought it from the estate of the original owner...

As you can see, it has wear, but it's fully intact, even has the original pull cord. The spark plug cap is chipped, and there's a shallow chip on a prop blade, but all original parts appear complete, and in good condition. There's a little rust here and there, and the gas tank paint is worn. Throttle works smoothly.
I have not tested further, the tank has no sludge or loose rust, it could be rinsed out I'm sure, but it was put away dry.

 I'll let the photos say the rest. 
Ask any questions prior to bidding please!

This will be shipped UPS ground, within 3-4 business days after payment is received. I have to obtain $40 in packing materials, and that takes a little time. 
NOTE: Partial assembly will be required due to shipping constraints, nothing major. May remove two bolts on tank, and pins to detach the mount, will not remove prop... 
Shipping this will be a chore to say the least!
Local pickup, or delivery by me is possible, even preferred, within the Austin, San Antonio Texas area for a reasonable fee, which would save you a bundle...

This, is the one you want to use, so the other one you've got, can stay on the wall! Or, you want to make it like new? Here's a solid one...

 Unless stated otherwise, nothing I sell will ever have foul odors, or soiling... 

If you buy from me, my goal will be to make you happy. If there's a problem with your order, please contact me to work it out...

Thanks for interest in my item!
