"Fresh Air"

  1. Muffler Mod for an Olson

    There is an old saw about choosing whether to "raise the bridge or lower the river" and after our new engine was installed we had to deal with this kind of decision.

    To wit: the distance from the top of the exhaust elbow on the engine needs to be XX inches above the top of the water lift muffler body in order to avoid possible back flow.
    Our former Universal diesel had a higher cast "neck" than the new Beta. The Beta has an optional higher one, but it would ...

  2. New Location: Racor & Lift Pump

    As a part of the engine replacement project, we decided to move the Racor and electric lift pump out of the engine bay/compartment. Current ABYC "rules" seem to demand a metal bowl under the clear filter bowl, and this seems to defeat its purpose as a way to see any water accumulating. Further, the engine compartment in a small boat is crowded already.
    So I moved the location for the coolant overflow tank from the under-cockpit-seat area to the engine compartment. This is visible ...

  3. Wiring & Engine Detail, part 2

    These photos show the Halon bottle in place, and also a much better look at the inside of the compartment where the meter and terminal strip are mounted.
    As an "extra" there is a shot of the new coolant overflow tank showing how the level in it almost matches the hose take-off place on the coolant cap. This is preferred to having it higher or lower.
    The former Universal diesel had the coolant bottle mounted somewhat higher, in the port seat lazaretto under the hinged cockpit ...

  4. New Hour Meter & Halon Status light (part 1)

    After removing the old (crumbling lens) Halon status light in its escutcheon plate, I needed to install a new one. The purpose of that light is to see if the Halon extinguisher has discharged, without opening the hatch to the engine compartment and potentially re-intorducing fresh oxygen when the suspected fire is hopefully out but the metal is hot enough to re-ignite. Or so goes the theory.

    Current ABYC "rules" want this light installed on your Dashboard where you would ...

  5. Starboard (under) Side Deck Reveal

    Here are some pix of the underside of the starb. deck above the galley. I opened up this area two years ago to get at the wiring that goes thru there to the next area aft, the overhead in the hanging locker.
    At the time I was changing all of the bulbs out for new LED bulb assemblies. The original fixtures are still looking like new, FWIW.

    I needed to clean up the wiring that fed the bulkhead light and the light over the aft berth. Factory had used 3-way crimps for these wires ...
