Operating In Salt Water Or Polluted Water; Operating In Shallow Water - TOHATSU MD 35B2 JET Owner's Manual

M25 Jet Drive
• Know the waters and area you will be boating; tides, currents, sand bars, rocks, and other
hazards.
• Check steering for free operation.
• Check for debris around the rudder and reverse gate which may jam or hinder operation.
• Before launching, examine the jet drive water intake for obstructions which may prevent
pumping of water.
• Ensure the driveshaft bearing on the jet drive is lubricated.

Operating In Salt Water Or Polluted Water

If the boat is kept moored in the water, always tilt the outboard so the water intake is completely
out of water when not in use.
Wash down the outboard exterior and flush out the exhaust outlet of the jet drive with fresh water
after each use.
When used in salt water more than in fresh water, remove mounting hardware, grease, and
reassemble once a year. Failure to do this may result in hardware that is difficult if not impossible
to remove at a later date.

Operating In Shallow Water

The life of the impeller and water intake can be greatly increased by avoiding the intake of sand
and gravel. The intake suction will act like a dredge when the water intake comes close to the
bottom. It is better to stop the engine and drift up to shore when landing, and to shove off with
an oar when leaving. The engine can idle through areas of water less than 61 cm (2 ft.) deep, but
there should be more than 61 cm (2 ft.) of water under the boat when increasing speed to reach
full plane.
Once the boat is on plane, the boat speed will prevent the ingestion of gravel and other debris
from the bottom. The suction is still present, but the water intake passes too quickly over the
bottom to allow debris to be drawn into the water intake.
When boating through shallow water areas, choose a course of travel that avoids sharp rocks and
other underwater obstacles that could damage the boat. Running the boat through these areas on
full plane may be helpful as the boat will be riding higher in the water. If the boat gets stuck on
the bottom, immediately stop the engine and move the boat to deeper water.
