biggest difference is the gearcase and prop.

Motor # 2 is a international model manufactured in 2005
Didn't found a match for the US/CAN market on my files but the "closest/similar" match for US market is F50TLR

Motor # 1 match with a FT50BET internacional model

thank you

I understand the lower unit of the t50 makes it the high thrust ?
your guess:: will the lower units switch ? I am going to find out tomorrow

(1) model T50 TLRC serial # 64JL1004290
(2) model f50 DET serial 3 60AL1000097

took lower unit from #1 and installed on #2
all seems to fit ok
will install engine on vessel today

back at you all later

the propshaft anf gear ratio should be different between the F and the T models.
other than that, not much changed.
