Information needed:

I have a 1996 200 HP Mercury EFI with a gear ratio of 187:1. The lower unit locked up the other day. I have a new lower unit on a 2000 150 HP Mercury with a sticker on the lower unit reading 187:1 Gear ratio.

Will the lower unit off of the 150 HP fit the 200 HP outboard?
I think if the gear ratio matches up, they will work.

I have a tourney coming up in a few weeks, so any help ya'll can give me I appreciate it.

Thanks,

Jared

The 150hp you have must be a Xri or Xr6 as these had the same gear ratio as a 200hp, standard 150hp(2liter and some 2.4 liter) are 2:1 ratio.As long as ratio are the same ....no problem.

And if not just means a prop change of 200/187 = 7% more pitch if all else in the prop is equal...for a 17P means 18P and for a 26P means 28P, or the next inch up if the engine rpm's can stand it and may be more readily available?????????
