Another one eliminated:

[CODE]Sm(1033) = 30915171019253321813 * C3005[/CODE]

I have trial factored the first 25000 Smarandache numbers to 2^32 with a C program. The factors are attached.
PrimeForm/GW has prp tested the cofactor of the first 10000, and those from 10000 to 25000 which have exactly one prime factor below 2^32.

No probable semiprimes were found beyond the two earlier reported: Sm(5053) and Sm(9706).
39 complete factorizations up to Sm(200) were rediscovered.
25 complete factorizations above Sm(200) were found:

Marcel Martin's Primo proved the first 12 cofactors. I am not planning to prove or prp test more cofactors.

Starting from Jens' list I can eliminate the following candidates:

This leaves the following as possible semiprimes between 97 and the next confirmed member Sm(5053):

In each case I have run at least 100 curves with b1=10000.
