225HP 2-Stroke restarting problem

[TownsendsFJR1300]

it attaches through the discombobbulator plate.
if that fails, you simply need an alternator.

not to be confused with a wobbeleator plate.

Duh....What colored alternator??? 110 volt, 220 volt???

ok
I have a 1995 225 Yamaha.
does it have a TPS?

That depends on the rotational direction of the #2 connecting rod...

Of course that's measuring at the large end journal...

What is No Alex, I mean rodbolt?

[rodbolt17]

it will all depend on that stupid model number.
the 225tlrt does not, its a carbed 2.6L.
the225txrt does,its a carbed 3.1L
the 225turt does as well,its also a carbed 3.1L

see how its possibly important to identify stuff???

other than paint code and fuel pumps the 2.6 and 3.1l motors don't share a whole lot else.

if you go with a 225tlrv the difference is even greater as the L indicates its a 2.6L carbed while the 225txrv and turv motors would be 3.1L EFI OX66 motors.

over the years there have been MANY subtle and sometimes not so subtle changes even with the same HP rating.

I thought you were playing trying to fool us with the wording. Yamaha Japan in the parts book and the tune up specs calls is a throttle sensor, not a throttle position sensor.

But, I agree with you wholeheartedly that a complete model identity is not good enough. For instance, I have a problem with a Yamaha 150 Vmax. Is it carb'ed, is it OX66EFI, is it an HPDI, is it a four stroke, all of which come with the meaningless Vmax designation.

[rodbolt17]

but Vmax sounds sooooo cool.

unlike the new SHO.

[boscoe99]

You got your regular output, your high output and your super high output motors.

I am still trying to figure out how a 225 HP HO or 225 SHO puts out more power than a regular output 225 HP motor.

Now is the Saltwater Series motor more corrosion resistant than a non-Saltwater series motor?

Is the SWS II propeller more corrosion resistant than the basic SWS propeller?

Is a Pro150 more professional than a non-Pro 150?

[boscoe99]

How about supermax ex-lax? Does it provide more ooomph out the exhaust tube?

225 TXRQ is the model number. Attached are photos.

What I notice now, is attached to the hose I can start and run the motor through all RPM no problem. If I try out on the river where the propeller has resistance the engine struggles and dies out. For example, today I tried out the motor with the hose for water source while on the trailer and all ran fine. I took the boat to run it WOT, I got off the dock opened it up a few times, then all of the sudden at idle it struggled and stalled. I got towed to the dock. When I took the boat home I attached to the hose again and it started right up and went to WOT. It seems load has something to do with it. RPM is 500 in water, and 700 out of water. It stalls at 1100 RPM in water nearly every time.

You are correct there is NO choke on this motor.

Since I don't quite get your outboard engine humor, I thought I would share a joke told to me by a football coach.


An old man was out Fly fishing at his favorite spot one morning, he cast out and reeled in enjoying the scenery.
As the old man cast out he heard a voice, hey look down here, it was a frog saying
"I will make your dreams come true if you kiss me, as I will turn into a beautiful maiden."
The old fisherman continued to cast and reel in his fly.
Again, the voice "Hey if you pick me up and kiss me I will turn into a beautiful maiden"
The old fisherman continues to cast and reel in his fly.
Again, the voice with the proposition.
So the old fisherman bends down and picks up the frog and puts it in his pocket.
The frog shouts "Hey I told you I would turn into a beautiful maiden"
The old fisherman replies "Well, I thought about it for a bit and at my age I think I would rather have a talking frog"

This guy brings his best golf buddy home, unannounced, for dinner at 6:30, after golf. His wife screams her head off while his friend sits open mouthed and listens to the tirade.

"My hair & makeup are not done, the house is a mess, the dishes aren't done. Can't you see I'm still in my pajamas, and I can't be bothered with cooking tonight! Why did you bring him home unannounced, you stupid ****ing idiot?"

"Because he's thinking of getting married."

[TownsendsFJR1300]

LOL on both above posts!!

Yep, looks like the TXRQ is indeed carbed;

I spent a few hours taking the carbs off / cleaning / reinstalling / test at hose and test at ramp today.

The carbs were very clean, all of them. There was one float that was a little out of range. The pilot screw was a 1/4 turn too open as per the yamaha service manual I purchased today. End Result: Ran perfect on the hose, however once submerged in the water it ran like crap and stalled out many times.

I noticed the prime ball does not stay hard all the time.

Any ideas? I am going to check the spark and compression at every cylinder to rule that out next. I am considering rebuilding the 3 fuel pumps too.

Thanks in advance.

[rodbolt17]

my first suggestion was to check the fuel pumps.
if they leak it idles like crap, more so under a load.
its not uncommon for the pump diaphrams to rupture.
it should be done as routine maint OR anytime the carbs are done.
only TWO of the pumps supply the carbs, the upper one with the two solinoids supplies the enrichment system via the top carbs fuel bowl.

if ANY rupture a diaphragm it runs like cwap.
