Minn-Kota Powerdrive v2
Been hearing a grinding noise from the gear box of my 7 year old Minnkota trolling motor. Is this common? Can it be lubricated?
Thanks

Grinding noise when you turn the motor left/right, or when the prop turns?
If it's the latter, then you have a problem. My guess is that you had some water enter the lower unit, it rusted out some of the components inside, and those rusted bits are causing the grinding noise. Either that, or the bearing is shot.
If you want to take it apart, you can get schematics (and any parts you'll need) from Northland Marine. Looks like the PowerDrive drawings are at:

Some of the links don't work, they made a mistake in the web addresses and you have to get rid of the extra "PowerDriveV2%202008-09/" in the URL.
Let me know if you decide to go this route, I can give you some tips and suggestions.

Shinbob, waiting the link you provided to download. Anyway, it's not the lower unit, works fine. the top unit makes a louder than normal noise when the motor is activated. Also, my foot control pedal doesn't turn the unit right anymore since I last used it.

Sorry, can't help you too much with the upper unit. Are you saying that when the prop is turning, there is a grinding noise from the head unit? That's odd, as there should be nothing mechanical going on up there if the only thing turning is the prop motor.
The shaft on my terrova is hollow, and is essentially an open tube leading from the lower unit to the top, i.e. not capped at all, so it's possible that you may be hearing noise from the lower unit being transmitted to the top? I'd still pull the prop and see if there's anything odd going on with the shaft.
I've heard of some issues with the powerdrive foot pedals -- checkout the iboats forum, they may be able to help you more over there. If you have a multimeter you can at least isolate the problem to either the foot pedal itself, or the trolling motor.

I listened to Devor last time I needed trolling motor parts and called John at jonestrollingmotor. John is very knowledgeable and has a huge inventory of parts in stock.
When I ordered parts last he was away from his desk but told me it should be around $60-65 (which is what it priced out to be from a different online retailer ) but if the parts were cheaper I would see it on my statement.
Sure enough when I got the parts it was $45. He could have easily charged me the $60 like I said was fine on the phone but he didn't. He now has a loyal customer for as long as he is in business.
