300hp and 350hp 8 Cylinder GENUINE Yamaha 4 stroke service kits

YOU MUST READ THIS 1ST. Ordering a 2 Stroke service kit has never been easier. Just select your hp and we will take care of the rest BUT you must provide your serial and model number in the notes section with your order. These are the common service parts and there is sometimes a few extra things needed like anodes or a thermostat but you can just select these separately by clicking here and finding your engine and adding them to the cart as well. Please read below to see what comes with each engine in the range. (If you have a HPDI engine please give us a call for the parts you will need)

Click Here to see what your serial number sticker should look like. We need all these numbers.

Picture 1 - You will get the appropriate quantity of NGK spark plugs for your engine.

Picture 2 - You will get a genuine Yamaha impeller.

Picture 3 - You will get either the water pump base gasket or the water pump housing O-Ring depending on what pump your engine runs when we look up your serial number.

Picture 4 - You will get the inline fuel filter for your engine. The picture shows just the most common one but styles do vary a bit and we will supply the correct one.

Picture 5 - New split pin for the prop shaft after you have removed the prop and greased the prop shaft.

Picture 6 - 2 new drain screw washers for the gearbox filler and drain screw.

Picture 7 - You will get enough gear oil to do your engine. A 2hp to 8hp will just be the 250ml squeeze tube, 9.9hp to 130hp will be the 1ltr bottle and the V6 engines will be both as they take just over a litre. Unless you have your own pump you will need to buy the screw in hand pump for the 1ltr bottle here.
