I know I should have asked this question prior to purchasing the engine, but just purchased what I think is a 2005 175 outboard.

If I understand the serial # correctly 754057 or the Model # 175ETXD it an Enduro with a 25" shaft.

The compression test (Cold) showed 120 Lbs in all 6 cylinders.

Are these known to be good engines?

Just trying to get some feedback.

Fresh water or salt ?-----Very good motors when new like all of them.------A lot depends on how it was maintained.-----Good looking does not count.

if its 2-stroke...... good up until the little linkage on the throttle that actuates the oil pump comes off.....

as Racerone indicated. a 16 year old boat motor is only as good as the care and maintenance it has received

Is there a way to confirm this linkage is functioning during the installation process, any oil indicator that lets you know there's an issue?

Will be installing soon.

Thanks/Jerry

no, there isnt any indicator. just check over everything

only reason I mention it....co-worker had newly rebuilt 2005 60hp 2-stroke (new power head and new lower unit) linkage popped off sometime in the last two outings....... motor started making lots of noise this past weekend (sounds like a bucket of wrenches in the dryer). linkage was off. compression down to 90/90/60. he's pulling the power head to have it rebuilt again. new crank, rods, bearings, pistons, etc.

That's why many boaters using 2 stroke automatic oiling systems are removing them and going for 50:1 pre mix after some years of usage. There's no indication when those systems fails, will surely know after the motor has been already screwed up due to lack of proper internal lubrication

Happy Boating

As machinery gets more complicated , expensive and easy to operate.-------The initial " new feel " is just wonderful.-----But as these new outboards get older there will cases of sad faces.-----Often some of this complicated electronic stuff can not be fixed or parts just are not easy to find.-----I can not believe the amount of ---NLA---- on parts for newer motors.----111torrance , now that you own the motor get a few manuals.-----Learn about the motor the easy way.----Often folks learn the hard way , which is via an empty wallet.

There is nothing special about the electronics of modern outboards. Nothing there that couldn't be fixed, upgraded or replaced outright if there is a market for replacement parts.

I suspect you'll find the OE's don't sale enough replacement electronics to make it worth the effort to source the material any longer.

Do you know of any electrical parts that is NLA by the OE and not supported aftermarket?

1990 model year motor. 30 years old now. One of the best that Yamaha ever produced.

The D in 175ETXD denotes D for the model year. 1990. Used again in 2005 but for different models.

Leave the oil injection system alone. One of, if not the, best made. The linkage referred to relates to how much oil is provided. If the linkage gets disconnected the system will default to the maximum oiling mode. You will know it by the amount of smoke or maybe carbon build up on the plugs. Easy to inspect the linkage.

A Yamaha multifunction tachometer is a useful tool to tell you the status of the oil injection system. Low oil in the remote tank or low oil in the main tank. Alarm will sound with low oil in the main tank. Motor will also go into RPM reduction mode.

Totally agree with this. Not sure I’m aware of many or any examples of these v6 particular oil injection failing when looked after. Nothing like as dangerous as the merc V6 versions. Probably about the only one I would trust
