RFI and Wiffle Balls

The rearview  picture gets the setup overlay whenever the marine VHF transmits.   It appears to be RFI from inside the pilothouse's navigation console.  Turning off the VHF's breaker, which also powers the cameras, removes the setup screen.  Since neither ham radio affects the video, I suspect the RFI is getting in via the common VHF/camera DC power breaker.

The wiffelballs worked today to keep the coolant from escaping.

Fuel Additive

This is the second round with Diesel Clean.  Each time the maximum recommended dosage was used--20oz per tank.  I'm hoping it will reduce the engine's exhaust smoke. 

Added coolant to the overflow bottle.  Hopefully the wiffle balls will keep the coolant from escaping from the cap's vent hole. 

Loosened the raw water pump from its flange but was unable to back it out.  I'd hoped to get some liquid gasket between the two to stop the small oil leak.  Next step is to pull the raw water pump.

Whistles

Nellie's whistles were sounding anemic. The problem lay in the compressor's regulator.  Not enough air could get by it.  The drain valve was removed and replaced with a female air hose fitting.  The line supplying air to the whistle was then plugged into this unregulated port.  What a difference, the whistles now sound great.

Desperate Times...

This is either an act of lunacy or genius but it is driven by desperation. Either way I hope to solve the problem of the leaking coolant overflow bottle. Coolant has been escaping out of the cap's vent hole.  Try as I may I have been unable to stop it. Even reducing the bottle's water level to almost nothing hasn't helped. The engine's vibration, and subsequent coolant sloshing, is the source of the problem.   Hopefully the balls will contain all the fluid well below the cap's level.

Anchor Washdown Hose

Finding the right length hose for the anchor washdown bibb has always been problematic.  While in Ace Hardware the other day I found a good solution: individual, aluminum, hose fittings (shown above).  The hose, purchased separately (under $1/ft), can be any length you like.  In the future, when the hose needs to be replaced, the aluminum fittings can be reused.

Replacing Deck Caulk


Teakdecking Systems SIS-440

Dug out some failing seams, taped the edges, put in SIS-440, used a putty knife to level the surface, and removed the tape before the caulk setup.  Got a great result.  The SIS-440 set up fast, stuck well, and seems the perfect durometer for a deck joint--not too hard or too soft.  The color also matches the existing caulk.  It's also priced under $15/tube.  What's not to like?

I bought this tube last winter and it summered aboard in the southern Florida heat.  Amazingly, the tube was still good.  Clearly, shelf life isn't a big problem.

Hydraulic Steering Pump Leak

There has been a slow hydraulic oil leak from the steering shaft for a while.  I was unable to wiggle the wheel off.  A gear puller was needed. Replaced an o-ring around the shaft.  Yahoo, it worked.
