I rebuilt the entire board and used it for a few years and it worked perfect. We were loading up to go to Celina last year and amphi would not start. One of the relays went bad. Better now then on the lake. I have spare relays, etc however I left it all in place and hooked up but took it out of the system by unplugging the connectors.


        

I agree with leaving the hardware in place but bypassing it electrically. I do not imagine that anyone actually waits for it to cycle before starting their Amphi? Most people jump in, turn on ignition, hit bypass button, and start engine. It adds no real value so I would rather not have to worry about it failing in the middle of the lake. I also think this was a USA only feature to meet USCG regs.


        

Yes it does add real value! Its is a good thing to keep operational. There is a reason it is required by the USCG. If you are on CG regulated waters and do not have an operational blower, they can impound your car and fine you. Besides why would you purposefully disable a safety feature as important as this. I always use mine for a short time upon starting. I keep tabs on what the exhaust from the blower smells like. If I smell raw fuel, I look closer to find the problem. When my tank is 1/2 full or more, I run it constantly while swimming or driving just to be safer.

This is what can happen if you have a fuel leak and don't use the blower...

You are not disabling the bilge blower, you are just bypassing the switch that you need to press before starting. Does anyone actually wait until the blower cycles before starting? Again, I think most people hit the bypass button as soon as they turn the key. I suspect that more fires are caused by leaking oil coolers or burst oil cooler lines than by fumes in the bilge.


        

I use the blower just not the timing part. I also installed one in the engine compartment and it keeps amphi running cooler in the hot summer when cruising slowly in the water.
