175 HP Fast Strike 1993 Johnson Lower Swap

[pthertel16]

Hey all,

I just had my lower unit go out on my J175GLETG and I purchased another lower unit but it is from a 1997 150HP Johnson. First thing I noticed is my original prop won’t fit. The thrust washer is smaller than my 175hp rated prop. Is the solution just getting a prop that will fit the smaller thrust washer? Will this unit be compatible at all or should I be looking to sell? The shifter and drive shaft look compatible but I’m worried that he water pump, gears, etc won’t be enough to handle the 175. Hopefully I’m wrong, any help would be great.

Tight Lines,

PH
