I would concur, running wide open isn't a melt issue, if it can do it
for 60 seconds it can do it for an hour. It will reach steady state
temperature very quickly being as light as it is, from that point on,
all waste heat goes out into the environment. The TBO is likely
effected but as cheap as these things are (being high volume
uncertified) who cares.

who really wants to run their SeaDoo at 90 mph all day?

I'd estimate a 40 mph cruise wouln't take more that 40 or 50 HP, well under
the peak.

Put the engine in a plane, and it'd melt.

Unless those sensors are there to prevent damage when it is run out of the
water for cleaning and rinsing salt out and such. I'd guess it is meant to run
WOT all day long towing inner tubes and wake boards.
