Power Pack replacement

[nickcunn]

I have gotten hold of a 1973 Mercury 40hp and it needs a new power pack. Is this an easy replacement? Also it needs a ingtion switch is this also something else that I can do myself? Thanks in advanced.

Neither job is difficult, get the proper replacement parts, the switchbox is all screws and nuts but the switch will require soldering

Thanks for the info can you tell me what color wires go where on the starter switch. I have a switch with a bunch of letters on the back. The motor did not have a switch to work with and I don't want to screw things up.

On the back of my stater switch it has the following letters.

B
S
I
M
M

Can anyone tell what color wire goes to each letter. This is a project that is going on as I type.
Thanks

B = Red; S = Yellow; I = White ( purple ); M = Orange (Salmon); M = Black. Run a jumper from I to one side of the choke button.

Thanks for all your help with the starter.

Is there any way to bypass the switch box? Was told the box was out and so far I have been getting quotes from $236 - $300. Please anyone help.
Thanks
