Took boat out for first time this year. 1985 Johnson 90hp v4. Faint rattle or tapping sound that gets faster but not really louder with increasing RPM. Not present at idle. Motor runs fine except for this rattle. It seems like more of a plastic sound vs a metal sound.
Toward end of last year I replaced the stator and then took it out. Ran great. Since then the only thing that has changed is I took my new torque wrench and set it to 102 ft lbs and tightened the flywheel nut a little more. I also changed lower unit oil. Before taking it on the trial outing late last year to test the stator I tightened flywheel to 100 ft lbs with my old torque wrench. Spec is 100 to 105.
I plan to put it on the hose tomorrow. Anything obvious I should check? I do have a nice voltmeter with DVI adapter and factory repair manual if needed.
