The particular parts needed for Yamaha F115 upkeep are consisted of within our Yamaha F115 Maintenance Parts Graph.
Allow's Get Started Doing Your Yamaha 100-Hour Upkeep
It is essential to put your engine over a non-porous surface like a concrete driveway prior to starting solution. This is necessary due to the fact that you are shielding the setting from any kind of prospective spills going right into the ground; second of all, you can locate dropped parts a lot easier than searching in grass or sand. Finally, perform the solution either under a cover or when you make certain there will be no rain. Water breach into your fuel or oil system is simply no good.
Collect your tools, make sure your parts are set out and obtainable, and also place on your protective glasses and also rubber handwear covers. Rubber handwear covers secure your hands from damaging effects of chemicals and also oils equally as safety glasses safeguard your eyes from any type of dashes or wayward components flying. To organize your components as well as devices, a portable device bench or the reduced tailgate of a pickup is quite useful.
Examine or Replace Flicker Plugs
We do spark plugs first as there is no sense in doing a full 100-hour service on a watercraft with a blown engine. The ignition system inspection as well as compression test will certainly tell you if there are a lot more serious problems that need to be examined before moving forward.
Initially, get rid of ignition system caps from each of the four plugs. After that take ignition system socket wrench loosening each and eliminating. Remember, "lefty loosey/ rightey tightey." As you take out the spark plugs, note the condition of each. If one ignition system appears to have any one of the following attributes, it might be a sign you need to take the engine in to be evaluated:
Carbon build-up triggering misfiring
The electrodes are worn and rounded
Down payments-- can trigger abnormal combustion and also melting of the electrodes of the spark plug and also engine damage
Overheated-- insulator of the spark plug is pure white, and also top of the ignition system is broken down.
Make sure to keep in mind which spark plugs your engine needs-- PartsVu suggests NGK. You will need 4 ignition system-- check out the Yamaha F115 Upkeep Graph to choose the right plugs.
Ignition system component numbers ending in a dash and afterwards two numbers (- xx) are already set with the proper void. We advise a pre-gaped NGK ignition system as opposed to attempting to void the plugs yourself. NGK ignition system designated with a letter "R" as BKR7HS-10 have included a resistor to decrease superhigh frequency interference (RFI). If your engine specifies an "R" styled ignition system, you must use it. Some engines are likewise equipped with resistor spark plug caps made to decrease RFI, which occurs whenever the ignition coil discharges. RFI negatively impacts computer-equipped ignition systems, digital determines, and radio devices.
Re-install the ignition system using only 18 lbs of torque to make sure that you do not break the porcelain shaft of the plug. Then, re-attach the ignition system wires. On the Yamaha 150 HP engine, they are numbered. On a lot of the V8 engines, they are divided down the left as well as the ideal side with each wire just long enough to reach the designated ignition system. If your engine's ignition system cables are hard to determine as well as re-attach in the right order, use some masking tape connecting the tap to the cord and also number it to make sure that you can find the correct order after you are finished. When installing the cords, pay attention for a clear-cut "click.".
Oil & Oil Filter.
An oil extraction pump is tidy, environmentally friendly, as well as without a doubt the simplest to make use of. These tools suck out all oil thru the dipstick port whereas the drainpipe method can leave some oil behind. No matter the method you choose, having an oil absorptive pad and store towel handy will conserve you time and discolorations on your driveway.
Using the oil removal pump: Remove the dipstick from the engine block, leaving the dipstick port totally free as well as clear. Place the nozzle of the oil extraction pump over the mouth of the dipstick port. Begin by hand pumping oil out of the engine by pumping the take care of producing the needed vacuum to extract the oil.
Once all of the oil is out of your engine, to continue completing your Yamaha F115 100-hour upkeep, remove the engine oil filter making use of a filter wrench. Have the shop towel and also oil absorbing decline pad all set as some oil will certainly come out when loosening up the filter.
We recommend correctly taking care of oil and also oil filter according to your neighborhood community standards. Your marina might have an oil garbage disposal area that can be used, or you might have to go to your regional oil recycling facility.
Currently, take the new filter in one hand and also with the various other dip finger right into extracted oil scrubing a light coat of oil over the seal of the oil filter. This aids to problem as well as prepare the seal to wed to the engine. You may hand tighten the filter onto the engine. The filter wrench is likewise valuable for those hard to get to locations or if your hand hold is not solid. Whichever method you utilize, do not overtighten.
Next, pour the proper quantity of oil into your engine- Oil Capacity F115. On newer versions, the quantity of oil needed is near the front of the flywheel cover. Likewise, on this label, you will see 2 columns with headings of SAE as well as API. SAE is United States oil weight requirements and also API is for international criteria.
Allow us make this very easy for you-- Usage 10W-30 oil. There are only two exceptions. First, you stay in a year-round cold water setting (Alaska). Or secondly, you reside in a year-round warm water environment (south Florida/ Florida Keys). These two exemptions make use of 20W-40. Every person else uses 10W-30 weight oil.
Utilizing the oil channel, put the appropriate quantity of oil into your engine. Area oil cap back onto engine-- hand tighten up only. Remember, the dipstick is the step by which you will certainly recognize the appropriate amount of oil is in your engine.
Fuel-Water Separating Filter.
We are firm followers in the regular replacement of fuel-water dividing filters. Making use of the wrench, unseat the gas water separator making use of a dustcloth to capture any excess fuel that may elope during this action. Draw the filter as well as examine it.
Gently lube the seal with aquatic grease so that it can be seated properly making a good seal to the place. Hand tighten up the filter. Do not use the wrench and also torque the filter tight as this can cause damage and may trigger the filter to lose the seal to the place.
There are fuel filters on the engine block itself and also depending upon the dealer/manufacturer, ideally, a 10-micron fuel/water separator system situated on the boat. Today's common use of ethanol gas has actually triggered a range or troubles with excess water as well as particulates in gas systems. To fight these issues, the installation of a 10-micron filter in between your gas storage tank as well as the engine block with its' collection of fuel filters will certainly stop much suffering later on in the future.

Even if you are acquiring non-ethanol gas Ring Free is advised with every fill-up. If you are making use of ethanol gas, Ring Free is a must.
T-9 Spray-- Liberally spray the entire powerhead down with T-9 spray, including electrical parts. T-9 assists to stop corrosion and deterioration, shielding your engine from harmful aspects. We additionally suggest spraying the whole trim as well as tilt unit with T-9 as an obstacle against the harsh impacts of water to which the trim and also tilt system is subjected.
Yamalube Marine Grease-- Utilizing a grease gun, ensure that you completely oil the zyrc fittings prior to finishing your Yamaha F115 100-hour upkeep. There are 3 of them: mid-section where the crankshaft fulfills the driveshaft and also one on either side of the guiding tube.
