Re: Mercury Mark 5 Lower Unit

[RICHARD A. WHITE]

Here is my thoughts… If you are building the MK5, you "should" be able to take all parts out of the MK6 case and just install them into the Mk5 case, benefits, it looks like the MK6 gears would allow for more speed as the are faster, if my math is right and I did not use a calculator so I could be wrong… Check the gear lash after installing and you should be good to go… Reading further is shows the 5 prop as being smaller, that would let the engine wind up a bit more, and the pitch is different, LOL…so they might just be equal…
Gosh I love Engineers……That last statement may not be true 🙂

Good luck and I hope I did not cornfuze you any more than normal 🙂
