lower unit compatibility

[coolrunning1]

I have a 1999 mercury (force) tracker 75 hp motor - serial # oe366999, model # h075412vt. Need to find out what lower units are compatible with it. Als, is there a way to look it up online? Thanks in advance.

Re: lower unit compatibility

The 70 and 75 used a Mercury designed lower unit with a prop from the Merc 40. The only two Force engines that used this lower unit were the 70 and 75 from the 1990s. It looks like the typical Merc lower unit and uses the same 10 inch diameter prop, but I don't know if a regular Merc lower unit would bolt up.
