60 Mercury Formula one engine

[mercury2.5]

I saw in a search where some of you guys had talked quite some time ago about this engine. I have a mini stv I got from Greg Scott for my son that Mike Nass had built for him, I put a 40 4 stroke short shaft I had but its not quite enough power for it. I ordered a 60 formula one race engine Friday and said it would be 90 days before expected delivery, was just wondering if anybody had any good information on these guys at all. Is it still just a 4 stroke or 2 stroke, from what I have read it seems to be a 4 stroke still, anyway was just curious on any details of how well it runs, if its a 4 stroke then it will run forever, just curious, 15" mid I suppose is all that's different, thanks for any input.

Stock 60 hp powerhead just like the fishing motor. 15" mid with attaching points for string steering.. Stock 60 hp gear case .. Nice looking motor but no warranty.. They are pretty bullet proof I have only change one powerhead in 12 years..
