On my last two 8-10 hour passages when I started heading in to the dock I noticed the engine RPMs took 10 or more seconds to respond to lever commands. Even more so for reverse than forward. Made for a dicey docking evolution. While running, the engine goes into reverse or forward immediately, I can hear and feel the clutch and see the water start moving. But when I go to throttle up, there is a 10 or more second delay until the engine ramps up to the RPM. So I clutch in, wait couple of seconds, move the throttle to 1800-2000 rpms and nothing for 10 seconds, then it speeds right up to the rpm's When not in gear, the engine responds fine to throttle commands.
When first leaving dock (engine @ 140 degrees) there is plenty of throttle response and no issues.
- I've checked the throttle cable and linkages and all appear adjusted properly.
- 25 hours since fuel and oil filter service. Sight glasses are clear, no bubbles and no leaks.
- Air cleaner is new at 25 hours.
- Turbo vanes are clean, exhaust elbow is not blocked.
- A little whitish, blue smoke at startup, but not burning any oil and the smoke clears after less than 15 minutes.
- Temps appear normal in the 160-185 range.
Thoughts?
