Mark, the closest I can come to the SF-N2-3/4 (part #334111) uprated pump is the Superflo 3/4hp (part #340037) a standard efficiency motor.
Would this be a better choce than the Hayward Tristar 1/2 hp?

I like the fact that theabove Pentairs are ported for 1 1/2 inch plumbing.
Who might ship a SF-N2-3/4 to Canada?

Thanks, Gary
