I seem to have the same ticking problem that I found in an old post, went out yesterday and made a full throttle run. shut engine off and when restarted noticed a ticking sound. On idle its not as loud as when its increased to 1500 or so and also noticed its got a double tap sound when returning to idle. I am 40 years master certified technician and have found this post. I will bore scope and compression and leak down today,
If it is the same piston skirt sound I would like to know if anyone knows the root cause (lean) and what can be done to prevent this after the repair. 1997 sport nautique 285hrs. Somewhere I seen reference to a PCM service bulletin for piston shrinkage, if anyone has a copy or direction for the repair of the root cause. Sorry to jump ahead without inspection, but think this is probably whats wrong. Also if reboring the engine, any suggestions on piston replacement that is better (teflon skirts)? Thanks
