I have a mercury 400 40 hp outboard.

I need a new switchbox for it. My question is, can I use the switchbox from a Merc 402? There is only a year production difference b/w the two, and the model number diff.

the part # for the 400 switchbox is 332-4172 and the 402 switchbox is 338-4733A2.

Normally I wouldn't even try mixing parts like this, but I have the opportunity to get a new 402 switchbox from someone for under 50 bucks. is it worth it?

any help would be very greatly appreciated.

Sorry no. The 70-71 400s used a completely different system than the 402 series 40 HP engines
