FYI, I went to check on the trailer today, I needed to pull the battery out for a recharge. My trailer had a cover on it all winter. So I opened the top of the battery box and found that its filled up with water. I don't know how it got in but I will be drilling holes on the botton of the box to let the water out. Let me know how did yours turn out.
Hi Rufus, nice rig. We just picked up a Hummingbird 17RK too. Is yours an RK? Have you winterized yet? I can find the water pump or water heater bypass in mind. I'm guessing it's under the mattress but not sure.
Thanks
Rob
