model 2007 115 hp optimax 115exlpto
max rpm 5750
i have an issue, the motor at idle sounds normal, when increase rpm it has a tick that is very noticeable.
power is as good as always
i have never gotten near the RPM that is says is max, the motor is all stock as I know ( bought used) my max rpm is 4900-5000 ish
the issue started after i warmed up the motor, idled out of no wake throttled up to 3/4 throttle and ran maybe 400 yards, motor slowed and died as if ran out of gas. i checked the priming bulb and it was very empty, i pumped it up and motor ran fine for 400 yards, died bulb empty again, reprimand and went on no more issues except the tick was there and is not going away.
plugs are not wet fouled, #3 is dry carbon black light filmed but not effecting spark test.
the ticking is in gear or in neutral,
I have compression checked the motor it is 97 #3, 107 #2 , 104 #1.
the compressor is new a year and half ago, with the belt removed it has no noise when turned over by hand.
the motor with spark plugs removed has no sounds when turned over by hand
the alternator has no issues when turned over by hand
the system makes no noise when turned over by hand and is no gear or neutral.
if someone can tell me how to upload the video you will be able to hear the sound of this ticking.
