Mercury Tower of Power - Lifeline 6's

[MARK BROWN]

Hey all, New here and need help with my inline 6 Merc, how interchangable are the parts and pieces from the 115, 135,150 inlines, Is it a pain or can most of the parts fit each HP, Carbs, elect etc...

Depends on year but quite a few parts will swap....the 125 and 135 are different block wise

Carbs, reeds and reedblocks, can vary, as can pistons, blocks and exhaust tuners. Ignition systems changed in the very late 70s. Gear ratios in the late 60 and early 70s sometime varied, but by 1973 were 2:1. In some cases, parts of the throttle linkages were different between hps
