Before you get started, check out Yamaha’s Maintenance MattersTM publication under Extended Storage then put together a checklist of everything you’ll need, and be sure you have the proper Yamalube® lubricants, additives and filters for the job. (A list is available in your owner’s manual and on our website). The correct amount of engine oil for your four-cylinder model can be found on late model Yamahas on the engine cover under the cowling. Your dealer also has handy Yamaha Outboard oil change kits that have the correct amount of Yamalube 4M, the Genuine Yamaha oil filter, and the drain plug gasket you’ll need to do the job right.

Now it’s time to refill the lower unit. Pete winterizes so many outboards he uses a bulk can of Yamaha lower unit lubricant with a pump, but you can use quarts and a hand pump available from your Yamaha dealer. Thread the fill hose into the drain plug hole and carefully pump in the lubricant until it starts weeping out of the upper vent. Pause for 5 minutes to allow all air to escape, then slowly pump additional lubricant until it comes out the vent hole again. Make sure to change the gaskets on both the vent and the drain plugs (do not reuse them). here

For the next step, Pete uses a portable fuel tank with a small amount of fresh gas treated with Yamalube® Ring Free, Yamalube EFI Fogging Oil and Yamalube Fuel Stabilizer and Conditioner. Start by placing a hose flusher over the main lower unit water pickups and turn on the water.

This is a 4-stroke 150 hp Yamaha Outboard boat motor for sale. This engine has a 20″ Shaft which is ideal for bass, flats, and pontoon boats. This engine is an EFI with only 415 hours. We have fully boat tested this Yamaha 150 and it runs excellent. The computer diagnostic and compression tests show this engine is within spec and ready to run. These are very strong and reliable outboards. They are very powerful for a 150 hp outboard engine. This motor would be ideal for a bass boat, flats boat, pontoon boat, mako style, whaler style, center console, or any boat that can handle a 475lbs. 4-stroke 150 hp outboard.

I seem to remember from marine tech school, that counter rotating, Yamaha lower units, were stamped with an L, just above the anticavitation plate, in the rear.

[im3w1l]

Beware of engines coming out of a distributor from Nashville. The "Salesman" swears that two 30" engines were ordered. He has no explanation why two counter rotating engines were sent.

I got confirmation on that L stamp, from several other folks also. My first suspicion was the LF in the model number [links]

Thanks in no small part to Yamaha’s dedication and commitment to the reliability of the Enduro line, they were able to produce future motors backed by a great reputation for reliability. In 1981, they began producing outboard motors for leisure use in the U.S. By 1983, they offered a lineup of two-stroke outboard engines that could get from 40 to 220 horsepower. Today they still offer quality lineups of two-stroke and four-stroke outboard motors in the U.S. more

[Broggly]

Yes, you’re going to pay more for a Yamaha outboard motor. Is it worth it? Absolutely. [links]

Yamaha’s reputation for reliability was earned through the consistent production of quality outboard motors. By offering innovative features and great control, Yamaha motors have powered everything from simple boats to high-performing cruisers. The dynamic performance of these motors combined with lower operating costs and better fuel economy makes for better boating experiences. here

Today, Yamaha produces outboard an assortment of dynamic two and four-stroke motors. How did Yamaha become one of the most trusted brands of outboard motors in the U.S.?
