    Battery tray for trailer

    I was wondering if anyone knows where I can get a metal battery tray to mount to my trailer tongue? I've got an electric winch on the trailer, and we tow the boat behind multiple vehicles. I was thinking it would be easiest to mount a battery to the tongue of the trailer so the winch will work...

    Acceptable compression on '87 4.3?

    I'm looking at purchasing a boat with a 1987 Mercruiser 4.3 liter 175 HP in it. The dealer said the compression tested cold at 105-110. We tested it warm and it ranged from 125 and 135. I'm new to I/O's, and was wondering if this is acceptable compression? I'm trying to make sure I'm not...
