what to look for and what to stay away from in used #6 drives
looking for a little education on # six drives. what are the diffs and advantages of wet vs dry sump, and any other info i should consider when looking for a pair. how often does a #6 need to be gone thru if your only putting 1000 ho thru it? thx for any input or advice, ratman

A dry-sump takes about 4 quarts of fluid and a wet-sump takes about 4 gallons. That ends what I know about #6 drives, except that they are phucking coooool!!!

#6 wet sumps are not getting hard to find parts for. However, dry sump is the way to go. The wet sump six can be transfered to a dry sump for about $5000.00. Water in the drive is defiantly something to note. Also how much power has been in front of it and did it have trannys or crash boxes. Believe it or not but a bravo drive takes more power to turn then a dry sump #6 drive. Check the prop shaft to see if it is bent with a dial caliper. I believe spec is .003 from merc however I know you can get away with a touch more. Find out if the drive has ever thru a prop blade. These are just a few things. Thanks Cam-shaft.

Re: what to look for and what to stay away from in used #6 drives
They have a tiny little oil pump in them like an early '70's electric shift omc 4 cyl drive. Any water or dirt will wreck the pump in short order. Drive damage is next. If youre paying alot for one, send the oil out and get it checked at a lab, this may tell you whats goin on with it. have someone check the backlash too. I think they are pretty neat drives, but I have seen alot of them apart at a local shop. I've never seen a Konrad have to come apart yet. Maybe because they are less common, but I'm thinking they will need less servicing than anything Merc. makes < BBB

Ratman I think I remember you telling me you persued a
different route.
I am by no means a SSM guy however I just learned this.
One little trick to check for wetsump or dry sump
is on the lower unit right under the cavitation plate
there is a drain screw this is a indication of a dry sump.
I droped my lower units and there is a spray bar inbetween
the gears. Another indication.
Kind of a surprise because I bought the boat thinking they
were wet sumps
