I have a 1995 Sea Ryder W/ 120 HP Mercury Sport Jet ( Force Out Board ) so I am told , Its 13 spline ..The power head has a hole in the block ,, Looking at other Force power heads , Can any one tell me what power head is interchangeable? Thanks In Advance

I play a lot with the 90 sport jets but I know that the block for both 90 and 120 are the same as outboard the only difference is the Crank Shaft . I currently researching with no luck but was told the old force o/b that are white have 13 spline shafts . Hope this helps .
