Maintenance; Break-In Period; Before Each Outing - Tayana 37 Operation & Maintenance Manual

The standard fuel tank is made of black iron, is baffled, and has a
large manhole with bayonet gauge. A copper fuel line is taken to
the engine's primary filter through a ball valve normally located
right by the fuel tank. Depending on the type of engine, the fuel
return line may inject fuel back into the fuel line at the engine filter
or lead excess fuel all the way back to the fuel tank. It is a good
idea to install at least one line filter/water separator and an electric
pump into the fuel line before you undertake any long voyages.
The electric pump will make it far easier to bleed the engine
should that be necessary.
Raw water for cooling is taken in through a seacock generally
located behind the engine. Note that this intake line has a large
filter before the engine. Cooling water is led to the heat exchanger
in the fresh water reservoir and then into the exhaust system to
cool exhaust fumes.
b. Maintenance
Please consult your engine manual for detailed procedures. The
engine manual must be followed exactly to obtain maximum
engine life and to keep your warranty in effect. The following
sections summarize the maintenance requirements described in the
manual and are intended as general information only.

(1) Break-in Period

During the first fifty hours of operation, the engine should not
be run at maximum rpm. At fifty hours, the following service
should be performed:
(a) Change engine oil and filter.
(b) Tighten cylinder head nuts in correct sequence to correct
torque.
(c) Re-set valve clearance and check oil feed to rockers.
(d) Check belt tension.
(e) Check all external nuts, set screws, etc., for tightness.
(f) Check shaft coupling alignment.
(g) Check fuel, oil and coolant levels and look for leaks.
(h) Adjust idle speed, if necessary.
