Every time I have cracked the water pump open, I have found the impeller
is in bad shape and has shed a couple of blades. The impeller
doesn't seem to make it beyond about 250 hours; I can't see any way it
would make it to 1000 hours like Yanmar says. In cold weather, the
engine has started in reverse a few times. Anytime the engine
turns backward, the impeller will likely be seriously damaged. |

size (inside diameter), 26 mm outside diameter, and 8 mm deep.
It's an open steel cage type. The
NSK bearing number means:
- 6 - Metric
- 0 - Extra light duty
- 00 - 10 mm bore size
- blank - Pressed steel cage type
- blank - Open bearing
- blank - Retention method: plain outer ring
- CM - Internal clearance: electric motor clearance

O-ring, Water Pump to Engine Seal |
National O-rings 6035030 |
|
|
1AG, 35 mm O-ring. Note: The same O-ring is also used for
the oil filler cap. The O-ring number means:
- 1A - Nitrile Rubber (NGA), Durometer Shore 70A
- G Series - For mounting applications (as opposed to rotary shaft
seals, etc.)
Inside Diameter: 35 mm
Outside Diameter 41 mm
Thickness: 3 mm
It's basically your cheap, garden-variety O-ring. No big deal. |

Water Pump Assembly |
|
|
|
I end up having to rebuild my water pump about every 250
hours. I bought a spare pump assembly so I could keep the boat
running while I took my time doing the pump rebuild. The pump
seems to quickly develop leaks around the seawater seal. The water
flows through the pump water drain hole, dripping onto the front face of
the engine block and then onto the oil lines underneath. The
result is corrosion on the engine block and oil lines. |

100 hours |
I usually change my
oil about every 50 hours. I use 15W-40 because I run the boat year
round; in hot and cold weather. The multi-viscosity oil is easier
for the engine to pump in colder weather, and
the Yanmar manual says it's OK to use. It's less fuss for me to
stock and use just one type of oil. If you run primarily in warm
weather then straight 30W is fine.
Quantity:
> 1.3 liters (44 oz) without filter change
> 1.5 liters (50 oz) with filter change. |

This is a
⅜ x 31 inch V-belt used on engines
with
serial numbers 03691 and higher. Original equipment is
a Mitsubishi REMF-1305 V-belt, but I have had trouble finding it. The Gates 7300 and Dayco 15300 are close matches. The
Dayco 3vx300 and Duralast 15300 will work well, even though their
dimensions are less well matched. The belt is properly
tensioned when you can depress the belt 10 mm at a point half-way between
the two pulleys. |

Oil Lines |
|
|
|
There are three external oil lines. One at the rear of the engine
and two under the fresh water pump. Water leaking from the pump
drips on the front two oil lines. These oil lines carry engine oil
to and from the oil filter. The salt water causes the lines to
rust out over time. I fabricated replacements. Here are the
salient dimensions: > Diameter of oil line tubing: 8 mm
> Original tubing material: steel
> Replacement tubing material: copper-nickel alloy (corrosion
resistant)
> Banjo fittings: 12 mm inside diameter (banjo bolt hole).
Designed to solder/braze to 8mm diameter tubing.
> Banjo bolts: m12-1.25x25mm (31 mm overall length). These
should be high flow bolts, not the brake line type bolts. The
brake line bolts have small diameter fluid holes and will restrict the
flow of oil. I couldn't find a high flow version so I bought a set
of brake line bolts and drilled them out. The fluid holes should
be 6 mm in diameter. Turn the bolt with a 19 mm wrench.
I made jigs from blocks of wood. These let me bend the tubing just
right to make replacements. |
