OWNERS MANUAL
1.
Trailer Launching
. Before launching make sure that all drain plugs are in place securely. To drive off of the trailer, the
intake part of the jet drive should be immersed in the water. Use low speed and gentle handling when driving on or off
the trailer.
2.
Starting
. Always start your boat in neutral. Warm up engine properly.
3.
Break-In Time
. The thrust bearing and shaft packing, and or the mechanical seal need break-in time to insure long life.
4.
Packing Gland Inspection 12-S, 12-TD, AT-309, TJ-309, & J120-AT
. After the first hour of the break-in period the
packing gland should be inspected and adjusted if necessary. With the boat in the water and the engine running, tighten
the packing gland nuts equally. Excessive tightening of the gland will result in heat damage to the shaft. Excessive leak-
age of the gland can result in poor low speed acceleration and possible water damage to the boat engine.
5.
SD-309 & SD-312 Weep Hole Inspection
. A weep hole is provided to indicate the condition of the mechanical seal.
Water running out the hole is an indication of a failed seal or that there is foreign debris between the seal faces i.e. fishing
line etc. A blast of compressed air in the weep hole will sometimes clear the obstruction. If it continues to leak, consult
your dealer.
