2007 Rinker 370 EC

370ec

I have a 07 370 Express Cruiser, we went to check everything out this weekend and the shower is draining extremely slow. Does anyone know is the boat has a sump? If so where it is located? And what the part number for the pump? would be so that I can take one with me when I go to the boat next weekend. (I live 3.5 hrs from the boat)

Thanks for the help

Welcome to the RBOC. On my 342 its located in the aft cabin on the port side under the bed cushion. You may just have to clean it out. I run white vinegar through mine a couple times a season to help keep it clean. Good luck and keep us posted on what you find....

On my 280, I have the 500gph model 4141. I replaced it this year and the best price was on Amazon.

We found out the hard way that using the clear soaps and shampoos cause fewer clogs than the ones you can't see through.

On my 05 360 the sump box which contains the pump is located in the floor storage locker at the bottom of the cabin stairs. It is tucked up closest to and underneath the bottom stair. Mine drains slow too despite cleaning. I think the drain line is undersized.  If I recall mine uses a Rule pump.

I can probably take some photos of my '07 370 tomorrow if you want.

This is what my 2007 370 has:
Attwood Sahara series S500
Pump model 4505
500 GPH

It is located at the keel directly inboard of the head, in the sole locker next to the air conditioner pump.  (Same location as on the 360.)
