 |
|
Is it normal to hear a little scrapping when engaging the engines for the first time after a gear oil change?
I followed the manual but am uncomfortable with what I heard. The scrapping went away after a few seconds and didn't return then I tried again.
Was this sounds a result of the initial oil circulation?
Would this happen if the gear oil was too low?
I called a suzuki mechanic and was told they fill the gear oil and "let it settle" and then add more. |

It is fairly viscus oil. Check the top fill hole to be sure that there is oil there.
Scraping sound is not normal…but if it went away, should be OK. I do wait until the oil has settled before running the engine.
There is often a "clunk" as you engage the gears, with engine idling.
Not much in the oil change which can go wrong.

Sand between prop & housing will make a grinding noise.
If the gear case is making the noise you would have a Bunch of metal chunks in the oil you just changed.
Have a good one. |
