I picked up my seawind the family bought me for my birthday yesterday. Mine seems to have been upgraded as well. I will keep mine water only as well but it sure is a pretty plane. Father in law had the real one on order when it was still a Canadian venture but passed away before he could take delivery and his yard aped son sold it back to the company (he's a real pilot).
We (sons and I) start work on it tonight. I went with the OS 91 4 stroker in mine. Also have a Neptune 40 that maidened two weeks ago at Boshkong lake in Haliburton Canada. Gotta love them seaplanes!
