i have a 1998 volvo penta sx cobra outdrive. is there supposed to be any moving parts in the outdrive while the outdrive is not in gear? the noise seems to get quieter when i put the boat in gear.

All the gears in the upper are spinning any time the engine is running. What kind of noise is it? A rattling noise may be heard if the engine isn't running as smooth as it should, it's from the backlash in the gears.

I assume you did check the gear lube.

Re: Noise in volvo penta outdrive?

the engine runs fine, i just had the outdrive serviced. i checked the fluid level myself before i took my boat out, it was overfull so i called the repair and told them that it was overfull and i was told that it would be ok. its kinda hard to describe the noise, sounds like a knocking noise to me. is there a normal amount of noise due to the gears turning. if the gimbal bearing is going bad, what kind of noise would it make?
