Boat › Outboard › Mid section

The midsection generally doesn't require much attention, but does help attach the outboard to the transom of the boat and houses the outboard's exhaust, driveshaft and cooling water pipe.

The leg off, and what passes through

With the leg off this old outboard, you can see the cooling water tube that comes down from the water jackets and slots into the water pump as the leg goes back up. A little later (at 12:17) I show where the exhaust comes down through the leg and out around the propeller.

The engine mounts have excessive wear and need replacing

Open ›

If the engine mount rubbers are worn or perished you may notice the outboard motor move or be heard to clunk as you shift from forward to reverse.

The exhaust muffler has corroded or its seal has failed

Open ›

An outboard's exhaust travels from the bottom of the powerhead, through the muffler, down into the lower unit then out through the propeller.
