Hi!!
My Tohatsu 9.8 2009 4st (with abt 50hrs) started to make strange noise.
After a few moments when under load ( sometimes 3-4 secs, sometimes after a minute or so) makes really loud high pitch noise, sounds like whining tranny to me.
Increasing revs increases the noise level and pitch.
Nothing when idling, but noisy on F/R gears.
Motor works for a while on forward gear and idle revs normally but sooner or later I got that terrible noise, no matter revving orr not
I brought my OB to the dealer a week ago, but so far they are unlucky after assembling/dissasembling lower unit couple of times already.
No signs of mechanical wear, slack etc.
I had not hit anything
OB used with Quicksilver 270, fresh water only (river estuary)
Any ideas, previous experience !????
