There should be a law that boat designers should be forced to service their own boats. That might make common maintenance tasks, like changing engine oil, a little easier. In most inboard or I/O engine installations, changing engine oil is looked on with the same fervor as going to the dentist.
This is a perennial question that seems to pop up on every sailing list I'm on at least once a year or more. Here is the official word from Yanmar on the subject.
Advisory Number: MSA08-003:
DATE February 8, 2008 Dealers and OEMs
TO: All Marine Distributors
SUBJECT: Gear in Neutral While Sailing All MODELS:
All Sailboat Engines
We continue to get questions regarding the correct gear position while sailing
with the engine OFF. This advisory is issued as a reminder; Yanmar requires that if sailing with the engine OFF (not
running) the transmission shifter must be in the neutral position or internal
damage to the gear or sail-drive will result. This damage will not be
covered by Yanmar’s Limited Warranty. Please instruct customers and dealers who
deliver the sailboat to the customer, of the correct (Neutral) position for the
marine gear while sailing.
If the customer desires that the propeller shaft not spin while sailing, either
a folding propeller, shaft break, or other suitable device may be used.
However, Yanmar accepts no responsibility for the selection, installation, or
operation of such devices. Please also refer to Marine service advisory “MSA07-001_Yanmar Sail Drive
Propeller Selection” for additional information.
If you have any questions regarding this advisory please contact a Customer
I have a 6 HP Tohatsu outboard. I have been looking for an in-line water separator for some time. All I could find were for larger engines. I would be even happier if I could find one for a funnel as I store gas in regular cans also and then could just put it through the filter when filling the boat. Does anyone know of a simple water filter?
Most of us running our inboard/outboards
(I/Os) and inboards in salt or brackish water understand the potential harm
that water can afflict on our expensive machinery. Corroded and leaking
manifolds and risers, blocked cooling passages and overheating engines, to name
just a few of the hazards.
One partial solution is a fresh water
cooling system, where outside water is used to cool the engine antifreeze in a
heat exchanger. This will help eliminate the ill effects in the engine block,
but the raw water side of the cooling system is still vulnerable to salt and
Another, better, option is to install a
fresh water flushing system in your boat. Such a system allows the engine to be
flushed with fresh water after you have returned to your slip. Most of these
units have to be added after purchase of the boat and vary widely in concept
and execution of the product.
