Re: Lower Housing Cracked 1957 Big Twin

[danblue]

Sorry, my wife is going to help me with the pictures. The crack is on the very top rim of the Lower housing…this lower housing looks like an upside shark fin. The lower housing has flat head screws holding it to the main housing above. The crack is just below the seam where the lower housing (shark fin) and main housing connect.

I spoke to Doug at VintageOutboard.com, and he said water had gotten in there and froze causing a stress fracture…the pictures do look like pressure from the inside caused the crack…I’ll try to get pictures for you all.

Thanks a million!
