I have a 1991 90hp Force.
Will a 1997 90hp lower unit fit it?

Any help appreciated, Thank You

Definately not. They changed to a Mercury style midsection and gearcase in 1995.

It may work.
But I don't like that seller.
I have dealt with him in the past, never again.
His listings often have mis-information, and he backs out of deals after you buy and pay for the item.
I see he is up to 34 negatives, and doesn't accept PayPal any more.

That unit has a 2 piece drive shaft, and a single port exhaust (exhaust exits from the exhaust snout above the prop).

Does your current unit have this exhaust type?
Or does it have the exhaust snout AND a through prop hub exhaust also?

You are looking for a unit that came from a 90-120-150 hp, 1990-1994, with 2 piece drive shaft, and either single port or dual port exhaust, whichever matches your current unit.
