Can I use any kind of oil in my Tohatsu 4-Stroke outboard?
For your 4-stroke outboard, you should use Genuine Tohatsu 4-Cycle Oil. Tohatsu 4-Cycle Oil has been specially formulated to handle the higher RPM's that outboards are subjected to, as well as special rust inhibitors to combat the harsh operating conditions of the marine environment. Genuine Tohatsu Oil reduces friction & wear and ensures the internal components are properly lubricated for optimum performance. If Tohatsu 4-Cycle Oil is not available we recommend using a 4-cycle oil formulated for use in outboard engines. An automotive engine oil with a rating of SAE10W-40 (API Grade SG, SF, SH or SJ) may be substituted.
Your Tohatsu 4-stroke outboard is equipped with an Engine Oil Warning Lamp. When the warning lamp is off, it indicates that sufficient oil pressure is present. If the warning lamp is on (red light is on) or blinking on/off, immediately shut down your outboard and check the oil level. Replenish as needed. If the oil level is at the appropriate level and the light continues to stay on or blink, consult your local dealer for assistance (do not use your outboard until a dealer has corrected the problem).
You may notice the engine oil warning lamp come on when you first start your outboard. This is normal and should go off after a few seconds.
Do I have to use any special type of gas (super unleaded, regular unleaded, etc) in my Tohatsu outboard?
The minimum octane rating that you should use is 87, however, we recommend using gas with an octane rating of 89 or higher.
I don't have any water coming from the "tell tale" water hole on my outboard. What should I do?
Immediately shut down your outboard! Do not start your engine back up until the problem is corrected or you will overheat and severely damage your engine. First check the water intake on your lower unit and make sure that it is unobstructed. If the water intake is clear then chances are your water pump impeller needs to be replaced or you have an obstruction inside your lower unit. Take your outboard to your nearest dealer for inspection.
How often should I have my water pump impeller changed?
You should inspect your water pump impeller each year before taking your boat out on the water. We recommend you change your impeller every year at a minimum depending on the amount of use you put on your outboard. One thing to remember is that even if you only use your outboard a couple of times a year you still need to have your impeller checked/replaced every year. Water pump impellers are made from rubber and will deteriorate over time even without being used (commonly referred to as "dry rot"); this can be just as damaging to your water pump as wear and tear.
I don't have a remote electric start engine, is there any way to shut off my Tohatsu outboard without having to pull the safety lanyard cord off each time?
Yes, simply press in the "button" where the lanyard cord attaches to the outboard. This will shut off the engine without having to remove the lanyard cord.
Do Tohatsu outboards come with lower unit oil already installed from the factory?
Yes. The lower unit gear oil has already been added at the factory, however, you should check to ensure it is completely full before starting your outboard for the first time. To replace/add lower unit oil we recommend any SAE 80 or 90 weight oil. You may also want to check out our web page giving you step-by-step instructions on how to change and check the oil in your lower unit.
Do Tohatsu 4-stroke outboards come with crankcase oil already installed from the factory?
NO!!! Tohatsu 4-stroke outboards are not filled with oil from the factory. Before you start your 4-stroke outboard you must add oil to the crankcase. If you do not add oil, you will severely damage your outboard. Running a 4-stroke without crankcase oil would be like running your car without oil...the engine will seize up and you will end up having to replace the engine block/powerhead (this type of damage is not covered under warranty). Please consult your owner's manual for the proper oil type and amount to add and for the proper break-in and operating procedures.
How can I tell what shaft length my outboard needs to be?
Measure from the top of your transom to the bottom of your keel. If it is from 15" to 17" long you'll need to get a Tohatsu outboard with a "short" shaft. If it is from 20" to 22" long you'll need our "long" shaft outboard. Tohatsu outboard shafts are measured from the bottom of the engine mounting bracket to the cavitation plate on the lower unit. Generally most boats need either a short or long shaft although some boats require a 25" shaft (ultra-long shaft) outboard.
What is the break-in procedure for my Tohatsu outboard?
The break-in period is the most critical time in the life of your Tohatsu outboard. Correct operation during the break-in period will prolong the life of your new outboard and will ensure optimum performance. Properly breaking-in your new outboard will ensure the initial smooth operation and lubrication of all moving parts (pistons, gears, bearings, etc).For a complete list of break-in procedures for all Tohatsu outboards (both 2-stroke and 4-stroke) click here.
