What did you do to your boat today

Anyone know what the white drain tube goes to in the picture? It drains into the bilge and goes up to the starboard side. I can’t think of anything on that side?

@Dream_Inn the generator starboard is held in place with 2 or 3 screws. I found in my 350 that if I remove the screws, I can easily slide it to access the back side.

Nice @Dream_Inn !
But would’ve been easier if you used an O2 sensor socket.

Burn.....ouch!

I need a new water heater....

I washed half of our boat today....we have 6 to 9 inches coming in over the next few days..waiting on a couple of parts to finish off the brakes.

My FB270 has a drain for the cupholders on the port side. Does the 330EC have cupholders or a cooler drain anywhere starboard?

My cup holders don’t have drains, only the 2 out by the swim platform. I think I remember seeing a plastic drip pan behind the access panel under the captain’s seat. It’s probably a drain for that. When I’m not doing anything, I’ll pull the panel and take a look.

Yesterday unloaded no brought stuff home. Today filled up and pulled her out, power washed the bottom. Winter isle this week.

Thanks @aero3113 for the prompt about your bypass - I got one and will fit this week ready.

So, we are anchored out today and decided to run the generator for some lunch. I got the ec60 error again! After trying a few things, I unplugged the sensor and started the generator for lunch.

Looks like I’ll be going back to marina tonight instead of staying out. Admiral was really looking forward to a nice quiet night on the hook.

I’m hoping maybe it is just the cheap sensor I bought on Amazon. Of course Kohler doesn’t make them anymore, so it’s what I’m stuck with. Anyhow I ordered a direct replacement and also the correct tool to change it out. 🙄. If it’s not that AI of course gives plenty of ideas, right or wrong

1. Water Intrusion into the Exhaust / Manifold

Cracked Exhaust Block or Manifold: A cracked or degraded exhaust block (such as Kohler part GM39129) can allow raw cooling water or condensation to leak into the exhaust stream and hit the hot oxygen sensor. [1]

Failed Catalyst / Riser: A failing or clogged catalytic converter / exhaust riser (such as Kohler part GM39607) can trap moisture or disrupt exhaust gas flow, wetting or shocking the O2 sensor and causing it to read out of range. [1]

2. Wiring and Harness Issues

Chafed or Shorted Wires: The wiring harness running from the O2 sensor to the SECM (Smart Engine Control Module) can chafe against the engine block, melt from exhaust heat, or suffer from corrosion due to the marine environment.

Corroded Connectors: Saltwater moisture inside the sensor plug can skew the voltage signal high, mimicking a sensor failure.

3. Fuel and Combustion Problems

Rich Fuel Mixture / Ignition Weakness: If the generator is running rich due to a weak ignition coil, bad spark plug, or a fuel pressure issue, the oxygen content in the exhaust drops significantly, forcing the sensor voltage high. [1, 2]
Exhaust Leaks: An exhaust leak upstream of or right around the O2 sensor can draw in ambient air or alter the gas readings, confusing the controller.

4. SECM or Controller Glitches

Module Communication / Ground Issues: A failing SECM or a poor ground connection to the engine controller can misinterpret normal sensor voltages and throw an EC60 error. [1]

I looked into the white drain tube. It is for a drip pan that’s behind the access panel under the captain’s seat.

With the hot water heater bypass installed, I was able to winterize the water system with only using 2.5 gallons of antifreeze. I don’t know why I waited so long to install it!!

aero3113 · October 9

I forgot to post this before. Found some mold under the head garbage pail. Nothing some Mold Armor and a hose couldn’t handle. Love that stuff!

rasbury · October 9

Oh my!

Dream_Inn · October 9

Mold armor from HD is fantastic!! That pink will be going into my boat in two weeks, but still enjoying tonight.

Ian · October 9

Mine wasn’t that bad but needed a clean too.

This morning I fit the hot water bypass and then winterized it all.

I think I posted this last season but a collapsible bucket works perfectly when cleaning out the strainers.

Today I cleaned up after winterizing, power washed the engine bay, cleaned the scum line off, took off all the canvas, put on its winter cover, strapped to the trailer all ready to back into the storage shed. All canvas washed once I got it home.

Dingy to do next week or week after.

Howdy, Stranger!
