How to select the propeller for outboards?
Propellers have two basic dimensions; diameter & pitch. Diameter is the distance measured across the propeller hub line from the outer edge of the circle that is made by the propeller’s blades during rotation. Pitch is the distance that a boat will travel if rotated one revolution without any slippage. When describing a propeller both the diameter and pitch are given. The diameter is referenced first and the pitch is second. Therefore, a 11? x 9? propeller would have a 11-inch diameter and a 9-inch blade pitch.
Theoretically, a propeller with a 11-inch pitch, when rotated one full turn, would advance a boat 11 inches through the water. In reality, no 11-inch pitch blade will advance a boat 11 inches with one full turn. This variance is referred to as slippage. In general, changing to a higher pitch prop will increase your top-end speed but reduce your acceleration (reduce your “hole-shot” power). On the other hand, decreasing the pitch will increase your hole-shot but sacrifice some of your top-end speed. If the hole-shot speed is important to you, for example if you pull water skiers most of the time, then you would want to go with a lower pitch prop and sacrifice some of your top-end speed but increase your hole-shot speed to get the skiers up faster. UNDER NO CIRCUMSTANCES SHOULD YOU EVER USE A PROP WHICH WILL ALLOW YOUR OUTBOARD TO OPERATE ABOVE THE OUTBOARD’S RECOMMENDED MAXIMUM RPM’s! Remember that in any application, discrepancies in performance can result due to the different boat hull designs, the final carrying load and your particular needs. NOTE: It is highly recommended that the outboard be checked with a tachometer to ensure that the engine is operating within the correct MAXIMUM RPM RANGE.
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 Parsun outboards with a “short” shaft. If it is from 20? to 22? long you’ll need our “long” shaft outboard. Parsun outboards 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. We recommend that you consult with your local dealer to determine which is the correct shaft length for your particular boat. Now we supply two kinds transom height for outboards.
The follow draw had explained the transom height in detail.
All non-ferrous metals spare parts are applied the surface chemical treatment without chromium. It improves the ability of anticorrosion and also avoids deleterious material left.
Adopt the high quality and high strength stainless steel to make the key spare parts, for example: shaft, fastener and Stampings.
Adopt the good surface paint coating to protect products against corrosion. All “PARSUN” outboards are treated by Well-known brand painting in U.S.A., in order to meet the needs of different materials and medium under different environment preservative effect, each of the relevant parts are sprayed the painting of four to six layers.
Adopt the self sacrifice anode to avoid the electrochemical corrosion on the outboards. Each “PARSUN” outboards have mounted the kirksite anode on the engine and lower casing. PARSUN will provide the new kind kirksite anode”PS09-1” in 2009. The new anode meets the U.S. MIL-A-18001K authority standards. Its base material is made by the purity of more than 99.995% of zinc. On the other hand, it add some special chemical composition, could provide the better anti-corrosion effect expend the useful time and simplify the maintenance
Because of outboards are used in the different working strength and environment, in order to ensure the outboards have the good performance and life, user must according to the owner’s manual to maintain the outboards. Especially require anti-corrosion maintenance for outboards. As follows:
The outboards need lift out of the water when non-running. Use the fresh water to clean the cooling water channel in the engine and surface of the outboards after running in the salt water.
Cleaning the surface attachment of the outboards, for example, seaweed, shellfish and other feculence.
If there some wear or tear on the painting when you using outboards, please carry out remedial work in time.
Please use alloy anti-corrosive under paint firstly, then paint the surface.
Regular inspect the anode
A. Check the anode after running every 50 hours (or three months). Use the multimeter to check whether the anode have the good electroconductibility, ensure the anode have the good conduction with relevant parts and connecting wires.
B. Cleaning anode. The anode surface would produce some new chemical compound produced by chemical reaction and attached with the aquatic in the water. These factors will cause the anode not continuing work. It will cause serious consequences if the anode could not be cleaned timely. You should remove and clean the anode by the fine sandpaper then re-mounts the anode on the outboards.( we recommend the customer use the new kind “PS09-1” anode to replace the old anode, this way will Simplify your maintenance work).
C. Change anode. It must change the anode when the anode excessive corrosion. Normally, we suggest the customer change the anode for every one year or one year and a half. To avoid the painting, greasing, oil attached on the anode when mounting. To ensure it have the correct physical and electric connection after mount the anode.
Overall, anti-corrosion maintain is an important work for outboards. As long as we maintain the outboards carefully and timely, it could solve this problem. At last, we recommend the customer use the “PS09-1” anode to protect the outboards and get the better result.
When you find it is difficult to start the outboards that has been stored for some time, please check the outboards carefully as instructed in our owner’s manual first .If after inspection, the outboards can’t start yet, we think you should clean the carburetor. Because the fuel in the carburetor would go bad after a long time and produce some particulate which thus affect the starting of outboards.
Besides, the fact if there is some impurity adhering to the needle of the carburetor will cause the fuel to leak from the carburetor.
Please remember to use the special washing agent to clean the carburetor and start the outboards as the follow steps:
Pull the starter rope slowly until the engine engages;
Pull rapidly to crank the engine;
Allow rope to return slowly;
Repeat until engine starts;
Push in the choke knob after the engine started.
Generally speaking, there are three reasons for this problem. The first reason is the cooling water passage was blocked, so you should check whether the outlet of the outboards has normal water current. 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 of 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.
The second reason is that the oil is too short. The last reason is that the end users start the engine out of water and then make the water pump to be damaged.
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 owner’s manual on how to change and check the oil in your lower unit.
Please note: there are not gear oil if the outboards transport by the air.
NO!!! Parsun 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.
What is the length of cable for Parsun Outboards?
There are two kinds of cables for remote outboards. One is the cable for controller; the other is the cable for steering wheel (Please note: there are 2pcs cables for controller, one is for throttle and the other is for gearshift). We normally provide 14’’ cables if you don’t have special request. But we can also provide different lengths of 12’’, 14’’, 16’’ and 20’’ for your option.
Please refer to the following drawings of cables:
Push in the choke knob after the engine started.
The cable for steering wheel
The break-in period is the most critical time in the life of your Parsun outboards. 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).
