Yamaha 130 2 stroke Blown cylinder??

[mattbat50]

Hi,

I have a 2003 yamaha 130 on an 18ft. mckee craft. We recently took the boat into a yamaha licensed dealership to get a small problem fixed. The oil from the tank under the console would not automatically go to the tank on the motor. we would have to manually pump oil into the motor every so often. The dealership said they fixed the problem but we still experienced low oil warnings and reguarly had to manually pump oil. about a week later we heard banging in the motor, like two poles hitting each other. We took the motor back to the dealership and they said that a cylinder had blown. I brought up the idea that they never fixed the oil problem but they said that if it was an oil problem all the cylinders would have blown. this is not correct. I called yamaha and they confirmed that just one cylinder could have blown due to oil Just wanted to know if anyone thinks the two problems are related and whether we should insist that they fix it for free. They want $3,900 to replace the cylinder. Thanks!

depende on how you were manually refilling the engine tank.
once the low engine tank alarm triggers you still have about 15min of oil left before the pump is dry.
what indicates was the tach giving when the oil alarm triggered?

hi, every time the oil got low, the tach would show one flashing bar (out of a possible three). and we would cut the motor off and refill the oil manually. There are two lines on the oil tank in the motor and we would fill it to the top line. It would run fine until the alarm went off again. It just seems odd to me that these problems occured so close to each other. Like a week apart back to back.

If you kept having to refill with oil because the alarm kept going off and you did not let it run completely out, then there should not be a problem from low oil.
I would have taken the boat back after I found out the problem was not fixed instead of waiting

ill ask again.
what METHOD did you use to manually refill the engine oil tank.
with only the left bar flashing it means the remote tank level or the switch or the remote tank wireing is defective.
even with the engine tank full you should have had a center bar lit telling you this.

oh ok. We used the switch on the motor that you hold down to refill the tank. The left bar on the bottom of the tac was flashing and the other two disappeard.

ok
that means the transfer pump and remote transfer wirining are intact and working.
why I was asking i if you pull the switch and screen assy out of the engine oil tank without FIRST drainig the tank ANY and ALL debris in the tank instantly head down the oil pump intake where it can block ouputs and inline check valves.
here is how the oil visual indicators work.
right bar only,remote and engine level ok, center bar, remote tank is low AND automatic transfer is prohibited however there is enough for two manual transfers.
left bar,remote tank is low AND the engine tank is low AND there is approxatly 15 mins of oil before the engine is damaged.
all three bars flasing,the remote level is ok yet the engine oil tank is low.
system malfunction.
means you had other issues and most likly never noticed the center bar lit.
it happens.
cant tell you how many times I get called about a horn, my first question is what is the visual indicates displayed,reply is invariably dunno didnt look.
had one last week,fixed the transfer problem,clogged remote tank filter, the guy called back all paniced because the far right bar with the green square was lit.
told him thats good.
he was freaked,said no way he had never seen it before.
he owned the boat since 99 and just last friday noticed the green far right bar.
