2000 supra launch 21 master power switch

[mikep]

I recently bought a 2000 Supra Launch 21. At times the master power switch (button) will not engage. The first time this happened was after the boat sat outside at the dealship when being serviced and a heavy rain filled the hull. Yesterday it would not engage and I'm guessing that it had something to do with the fact that it's been almost 100 degrees here for the last several days. Can anyone shed light on why this is happening? Should I replace the switch? If so, does anyone know who might carry one? Best I can tell the switch is an E-T-A 45-700-IG1-P10-DD and I believe it is 30 amps.

Thanks

Does it look like this: http://www.skidim.com/prodinfo.asp?number=45700IG1P10DD30AMP ?

If so I'd just replace it. They can get worn out and either not stay pressed (on) or will shut off momentarily with a gentle touch.

Yes, it looks exactly like that. Thanks for the help. I'll take your advice and replace it.
