Indmar 350 H.O., Operator'S Manual

Page: 16 / 80

Indmar Marine Engines 1-1
A new engine may use a more than normal
amount of engine oil before it is broken in.
Check your oil level hourly during the break-
in period. Once the engine is broken in,
check the oil level before each day’s use and
more often during sustained periods of high
RPM operation. Some oil use during opera-
tion is normal.
The following checks assumes your dealer has performed
the pre-delivery service and inspection. Complete the
following pre-start check list before starting your engine
for the first time. If you have questions about any of these
procedures, see your Indmar dealer for assistance.
FIRST TIME OPERATION
1. Check the boat hull and/or garboard drain plug. Make
sure they are installed and secure. Check the boat
owner’s manual for additional pre-operation checks.
2. Make sure all engine drain plugs are installed. Refer
to Chapter 7, Storage and Winter Layup. There are
several drain locations:
Block – Two drain plugs on each side; 5.7 Liter EFI
engines have an Engine Knock Sensor (1, Figure 1-2)
installed in one drain hole.
NOTICE
On the 8.1 Liter engine, removing the knock sensor
does NOT drain the block. Remove the plugs from the
brass fillings on both sides of the engine to drain
water from the block.
Exhaust – The drain hose must be connected.
Transmission – The transmission oil cooler has one
drain plug. In addition, the Walters V-Drive (if
equipped) has two drain plugs.
