    Mercruiser 4.3L 1987 s/n B459735. When I changed my oil earlier due to a flooded carb pouring gas in the cylinders, I checked the manual, and the capacity said 4.5 quarts. I put 4 quarts in and checked the level, and it was overfilled on the dipstick. When winterizing, I changed the oil again...

    Depth/fish finder test?

    So I've got a fish finder with a big 5" or so screen and a small depth finder that looks kind of like an old school pager. Both are humminbird. I see two black blocks off the transom on each side of the boat that say "humminbirg", so I assume they are the sensors. Problem is, neither of the...
