Putting a trim switch in and leaving the one in the handle. Problem wired it to the engine inside same wire 3 strand marine in sheath the up and down in handle work the same but the button is slow up but fast down. Connections clean same wire same length and thoughts? I hope not a bad switch. Rick

Don't know what motor your talking about but the bean counters at the mfg sometimes cheap out and do away with the relays on short runs . heavy wire is cheaper than relays on merc's they only use a up relay to carry the heavy load , down they let the harness wires carry the load since you have gravity helping I'm guessing with the original just internal (short length ) wires they tried to get away without a relay at all, so the new switch with long wires is probably giving you a voltage drop .so check for a voltage drop at the pump motor leads if there is a drop you have to ether rewire with heavy wire or install a cheap 40-50 amp relay $7-8 at radio shack another couple bucks for the socket if you want to bother otherwise just plain old stake on crimp's.

PS a good tip for crimp conecters go to a electrical supply shop a get a tube / bottle of penatrox it's a conductive anticorosion grease they use to splice aluminium and copper wire together with in salt boats it keeps the green/black crud out of the connections almost as long as solder and paint on neopreme.I'm suprised vey few if any marine supply places don't stock it

Baddjohnny would it be better to run the switch into the box? If so how ya do it? Are the wire the same green blue purple inside the box and do you interrupt it at the handle? old merc box late 80's. Thanks Rick
