1999 Yamaha 4 stroke 50 HP outboard ***Australia***

Hi everyone,

 

I am considering purchasing a used 1999 Yamaha 4 stroke 50 HP outboard with 364 hours on it. I dont know alot about Yamaha's or 4 strokes as far as reliability goes.

 

Has anyone had one that can tell me anything positive or negative about it?

 

I have heard that 4 stroke engines are good for upto 5000 hours, any truth to this? Anyone got one that has that many on it?

 

Does anyone know if the 99 era of 4 strokes had any problems in relation to beinfg carburated as now they have EFI?

 

Any comments will be appreciated,

 

Thanks,

Honestly, the simpler the better IMO with outboards. I hate 4-strokes, as the 2-stroke was GREAT. It had better take-off speed, it was VERY simple, never having to worry about changing oil. If you have an onboard tank, made it even easier, never having to pre-mix your oil.

 

As to the yami's, they are great engines. I know plenty of people using 2-stroke models from the late 80's to early 90's, with well over 3,000 hrs, running as strong as the day they were built. I have NEVER heard of a problem with any yamaha's, and would not doubt that 5k hours is easily attainable. 350 hrs on that motor I would call barely broken in.

I've got a 2000 Yamaha 50 4 stroke and it has been a great motor. Have had one issue with the tiny jets in the carbs getting blocked by something even with a racor 10 micron filter but I like it. Definitely does not have the hole shot that the 2 stroke does but top end it's the same. Just takes a few more seconds to get there. Barely burns any gas.
