Hello
I was on the hook over the week-end and of course it rained. Water got in the ignition swith and it shorted causing the buzzer to sound. What is the best way to water proof the switch? Is there a rubber boot that goes over the switch? I'm going to have a cover made to cover the whole control panel but I would like to have the switches covered with something with a key slot.
Thanks
 
I have always taken extra steps to keep my helm dry, that's the best bet. Although sometimes water can get in there. What kind of boat is it? If the problem is water seeping behind the dash panel, then you should put some self adhesive foam weatherstripping along the back edges of the dash panel, then secure the panel back in place. If the water is entering from around the ignition switch itself, perhaps a little bit of silicone around the hole will help. But don't use anything too agressive like 5200, you'll need to take that ignition switch out someday!
 
When I had to replace my ignition switch, it came with a rubber boot that had a slot for the key to fit into. But my helm is not exposed to water.
 
It's a 50 foot Gibson houseboat. The rubber boot with a key slot was what I was thinking about but don't know where to find them.The water got in thru the key slot. We had a heavy downpour when this happened.
 
Or you can hook up a toggle for ignition and push button for starter. There are boots specifically made for these type switches.
 
The rubber boot was included with the switch. Don't know if it can be purchased separately.
 
Our SR in signature was missing it when we bought it used. Mechanic rustled through his stuff and gave me a used one. Still, changing that switch might be a good idea. If it made up with rainwater in it, I think there's corrosion in there that made the water conductive. It used to be common for older MerCruisers to simply start cranking. Would kill the battery or burn up the starter. Good reason to have and use a battery switch.
