Hi All,
I have a raw water leak somewhere in the exhaust side of my Kohler 8OEZ genset on my Mainship 400.
The leak appears to be coming from the left side of the genset, the Raw Water pump and HE are on the right side. There is not much room between the left of the genset and the port engine muffler, so the exhaust elbows (there are two of them) are hard to see and reach.
I took most of the enclosure off of my genset about 10 years ago put left part of the frame in place to mount the controller. The Genset is mounted on top of a starboard board, which is then bolted to a fiberglass shelf. The starboard board is basically the same footprint as the old enclosure.
Here is the crazy thing, the leak is seeping out UNDER the starboard board, between it and the fiberglass shelf. Logically, the only way water could get under the board is if the leak is originating outside the board, unless it is flowing over it and down under it somehow. But the top of board is dry. Here's some more info:
1. It only leaks when the genset is running.
2. It's a steady drip coming out under the board.
3. The Raw Water Pump, Heat Exchanger, Mixer Elbow, Siphon break and all of the hoses/elbows in the exhaust I can reach are dry.
4. There is no water that I can see anywhere on top of the starboard.
5. The metal drip pan, which is under most of the genset, including the raw water pump and the HE, stays dry.
6. The exhaust elbows are over the starboard, but not over the metal drip pan.
7. I ran a new hose from the strainer to the raw water pump, by passing the old enclosure. It is not leaking.
8. I tightened every hose clamp I can reach. Still dripping.
9. I put paper towels under the exhaust elbows, they are staying dry.
I'm really stumped here. I may have to unbolt the genset and slide it over, which is a big job.
Any tips or suggestions?
