Components Needed
The certain parts required for Yamaha F115 maintenance are included within our Yamaha F115 Maintenance Parts Graph.

Let's Start Doing Your Yamaha 100-Hour Maintenance
Presenting Location
It is necessary to put your engine over a non-porous surface like a concrete driveway before starting solution. This is essential since you are securing the environment from any type of possible spills going right into the ground; secondly, you can discover went down components much easier than looking in lawn or sand. Lastly, perform the solution either under a cover or when you make sure there will certainly be no rainfall. Water intrusion right into your fuel or oil system is just no good.

Collect your tools, make certain your components are laid out and easily accessible, and put on your safety glasses as well as rubber gloves. Rubber handwear covers shield your hands from harmful results of chemicals as well as oils equally as protective glasses secure your eyes from any splashes or errant components flying. To organize your components and also tools, a mobile tool bench or the decreased tailgate of a pickup is quite valuable.

Evaluate or Replace Spark Plugs
We do ignition system initially as there is no sense in doing a complete 100-hour service on a boat with a blown engine. The spark plug evaluation as well as compression test will certainly tell you if there are more severe problems that need to be examined prior to progressing.

Initially, remove spark plug caps from each of the 4 plugs. Then take ignition system socket wrench loosening each as well as removing. Remember, "lefty loosey/ rightey tightey." As you take out the spark plugs, note the condition of each. If one ignition system shows up to have any of the following features, it might be an indicator you require to take the engine in to be evaluated:


Carbon build-up causing misfiring
The electrodes are put on as well as rounded
Deposits-- can cause unusual burning as well as melting of the electrodes of the spark plug and engine damages
Overheated-- insulator of the ignition system is pure white, and also top of the spark plug is broken down.
Make certain to note which ignition system your engine needs-- PartsVu recommends NGK. You will require four spark plugs-- check out the Yamaha F115 Maintenance Graph to choose the appropriate plugs.

Ignition system component numbers ending in a dashboard and after that 2 numbers (- xx) are already established with the correct void. We advise a pre-gaped NGK spark plug rather than attempting to space the plugs on your own. NGK spark plugs designated with a letter "R" as BKR7HS-10 have actually integrated a resistor to reduce superhigh frequency interference (RFI). If your engine specifies an "R" styled spark plug, you must utilize it. Some engines are additionally geared up with resistor ignition system caps designed to decrease RFI, which occurs every single time the ignition coil discharges. RFI negatively influences computer-equipped ignition systems, digital assesses, and radio equipment.

Re-install the spark plugs utilizing just 18 lbs of torque so that you don't split the porcelain shaft of the plug. Then, re-attach the spark plug wires. On the Yamaha 150 HP engine, they are phoned number. On much of the V8 engines, they are divided down the left and also the appropriate side with each wire only enough time to get to the assigned spark plug. If your engine's spark plug cables are hard to identify as well as re-attach in the proper order, use some masking tape attaching the faucet to the cable and also number it so that you can locate the proper order after you are completed. When installing the wires, listen for a clear-cut "click.".

Oil & Oil Filter.

An oil extraction pump is tidy, eco-friendly, and without a doubt the easiest to utilize. These devices suck out all oil thru the dipstick port whereas the drainpipe approach can leave some oil behind. Despite the method you select, having an oil absorbent pad and also shop towel accessible will certainly save you time and also stains on your driveway.

Making use of the oil removal pump: Remove the dipstick from the engine block, leaving the dipstick port totally free and clear. Place the nozzle of the oil removal pump over the mouth of the dipstick port. Begin manually pumping oil out of the engine by pumping the manage creating the required vacuum cleaner to draw out the oil.

Once all of the oil runs out your engine, to continue completing your Yamaha F115 100-hour maintenance, get rid of the engine oil filter using a filter wrench. Have the store towel as well as oil absorbing decline pad all set as some oil will appear when loosening the filter.

We suggest properly disposing of oil and oil filter according to your regional area standards. Your marina may have an oil waste disposal area that can be made use of, or you may need to go to your local oil recycling center.

Currently, take the new filter in one hand and also with the other dip finger right into removed oil massaging a light layer of oil over the seal of the oil filter. This aids to problem and prepare the seal to wed to the engine. You might hand tighten the filter onto the engine. The filter wrench is likewise helpful for those difficult to get to locations or if your hand grasp is not strong. Whichever method you utilize, do not overtighten.

Next, pour 6E5-45945-01-00 of oil right into your engine- Oil Capability F115. On more recent models, the quantity of oil needed is near the front of the flywheel cover. Additionally, on this label, you will certainly see two columns with headings of SAE as well as API. SAE is US oil weight requirements and also API is for worldwide criteria.

Allow us make this simple for you-- Use 10W-30 oil. There are just 2 exemptions. Initially, you stay in a year-round cold water setting (Alaska). Or secondly, you live in a year-round warm water atmosphere (south Florida/ Florida Keys). These two exceptions make use of 20W-40. Every person else utilizes 10W-30 weight oil.

Utilizing the oil channel, pour the correct amount of oil into your engine. Area oil cap back onto engine-- hand tighten only. Remember, the dipstick is the step through which you will certainly know the correct quantity of oil remains in your engine.

Fuel-Water Separating Filter.
We are firm followers in the regular replacement of fuel-water separating filters. Using the wrench, unseat the fuel water separator utilizing a dustcloth to capture any excess fuel that might elope throughout this action. Draw the filter and also evaluate it.

Lightly lube the seal with marine grease so that it can be seated appropriately making a good seal to the mount. Hand tighten up the filter. Do not make use of the wrench and torque the filter limited as this can trigger damages and also might cause the filter to lose the seal to the mount.

Gas Filter.
There are gas filters on the engine block itself and also relying on the dealer/manufacturer, with any luck, a 10-micron fuel/water separator system located on the watercraft. Today's common use ethanol gas has triggered a variety or troubles with excess water and particulates in fuel systems. To fight these problems, the installation of a 10-micron filter in between your fuel container and also the engine block with its' collection of fuel filters will stop much heartache later on down the road.

Lift Pump Outlet Filter-- usually a mesh style filter in a clear white real estate. Usually placed near the lift pump outlet or near the fuel VST. This filter needs to be replaced and can not be cleaned. On F150, F200/225/250 engines, the filter may be covered by a black rubber boot.
VST Filter-- located affixed to the inlet of the medium stress electric fuel pump inside the VST. Eliminate the VST and also inspect/replace the filter as routed in the maintenance timetable or as needed.
Injector Filters-- these demand special care, see your dealer for solution.

Even if Upgrade Aluminum Outboard Propeller 13 tooth are acquiring non-ethanol gas Ring Free is recommended with every fill-up. If you are making use of ethanol gas, Ring Free is a must.

T-9 Spray-- Freely spray the whole powerhead down with T-9 spray, consisting of electrical components. T-9 helps to stop 10.25 x16-G and also corrosion, shielding your engine from hazardous components. We also suggest spraying the entire trim and also tilt device with T-9 as a barrier versus the severe effects of water to which the trim and tilt device is revealed.

Yamalube Marine Grease-- Making use of an oil gun, make certain that you adequately oil the zyrc fittings before finishing your Yamaha F115 100-hour maintenance. There are 3 of them: mid-section where the crankshaft satisfies the driveshaft and one on either side of the steering tube.
