It is cold in Louisville on the Ohio River, and I thought it might be a good idea to replace my plug-wires and spark plugs this week. I have a 1989 Sea Ray 390 with HUGE Mercury engines. Any advice on a good plug wire brand and plugs? Thanks as always for the advice.

Thanks, everyone. I just ordered Merc 25W-40 from Amazon. Any advice on filters?

I had to replace both my impellers this year. Stupid Ohio River/ Harrods Creek. I pulled all the hoses and found most of the impeller pieces in the impeller housing, thermostat, and hose leading to the thermostat. You should be fine once you get most of the big pieces out and confirm you are NOT...

I was working on winterizing my boat, and the stupid seacock handle broke. This is a perfect example of an easy job going wrong. I live in Louisville, Ky and was planning on keeping my boat in the water this year. Questions: Should I try and fix this in the water? Any idea why the seacock was...

Hello All, The 115 Volt AC circuits are dead. I checked the shore power, and it is on. I also checked the fuse. Does anyone have any additional advice on what might be the cause of the problem?

Agree I pulled the space heater. It was a bad idea. Thanks
