Now that I have your attention...
I have an I/O and it goes hard into gear. As I am pushing the throttle forward (or backward) out of neutral I am greeted by a very heavy "thunk" sound as the outdrive goes into gear. It doesn't grind, it just goes into gear very hard.
This is not a new issue...I bought the boat one year ago and it has always done this. I've tried adjusting the idle speed but no matter how low I go, it doesn't seem to help (I've set my idle as low as 600 rpm and it still goes into gear hard). I changed the outdrive oil last August and saw no signs of metal shavings that would indicate my gears are being ripped up.
I usually get one of two responses from people riding in my boat...1) "Is it supposed to do that?" 2) "That means you have a good outdrive"
Does anyone have any ideas on what I can do to smooth the transition into gear? Should I be concerned about it?
FYI I have a 1998 Mercruiser 5.7L engine and outdrive.
