Hi All,
I have 1998 Sea ray 175 with Mercruiser 3.0 lx apha one. Somehow my blower fan and Bilge is not working. I replaced the new blower fan and it is not working. So it must be the fuse. I have no ideas where to find the fuse. I don't know where is the fuse panel on the boat at all. So please help me out. thanks.

I agree probably a fuse. Ive never worked on a sea day but I'd suspect you've got a fuse on your dash and possibly another inline fuse back near the device(s). Go to bilge pump and to the blower and trace the wires. If the wire are continuous and no inline fuses near the engine bay then it's likely you've just got a fuse on the dash or under. If you're not familiar with boats you may be overlooking a fuse cover if you've got little black round plastic things next to your switches, those are fuse covers, twist em off

fuse or circuit breaker would be at the dash, near the switch.

Wow. This is my first time joining this boat forum. I could not believe how fast of all the responses. Thank you very much to everyone. I will try to find the fuse under the switch first today. It is very funny. The blower switch on the dashboard are build on top of the radio. So in order to find out if there is a fuse or not, i have to take out the radio first. Thanks.

Might also be the switch. Use a meter to see if 12V is present

When you say 'bilge', you mean 'bilge PUMP'?

Being a bilge pump and not a blower, look at the specs of the pump you just installed. Should be no more then 10 but probably 7 or so
