Hi,

I've found all of your comments on re-foaming interesting. And thought I'd
send along some original Evinrude statements about the manufacturing
process:

Last night I sent some scans (which apparently are too large for the mail
list server) of the original Evinrude construction process.

Here's what the paragraph said of the original construction and foaming
process:

"Rigid, closed-cell polyurethane floatation (equivalent to 73 life
preservers) provides additional structual strength. Foaming is done under
250,000 lbs of pressure. Closed dies lock the hull in a steel embrace during
the foaming operation."

"Special foaming machines produce high-pressure foam twice as dense and far
stronger than poured-in foam. It can't "work" or develop voids; won't absorb
moisture, shrink. or pull away from the hull regardless of temperature or
operating conditions."

If you do the simple math that one live preserver could support an adult
weighing 170 pounds x 73 then that equals roughly 12,410 lbs of floatation.

I think Evinrude was more than meeting the floatation standards of BIA or
whoever it was reasponsible for setting such standards..
