I have an 07' 200 HPDI. I'm hearing a strange noise when the motor is in gear fwd or reverse until I bump the rpm up to about 900. It sounds like the gears are not fully meshed and it is kinda bouncing around in the gear. I think once I get a little more rpm there is enough pressure to hold the gears tight against each other.
I was looking at the maintenance manual and there is a why to adjust the gear backlash, but not something I could do. Anyone experience these symptoms? And is there any way to check this without disassembling the lower? When I turn the prop while its in gear how much play should there be if any? I'm gonna check and change the lower oil and see if makes any difference and the the prop nut is plenty tight enough. Thanks in advance for your input.
