I'm looking for shaft info (for prop purchasing) and HP/torque rating for #7 drives.

Thanks

#7 ?

You're looking for info on something that does not exist???

https://www.mercruiserparts.com/bam/.../31026/2322/60

here’s a breakdown of the lower for a 7

they were marketed more for an express cruiser type of boat

For Diesel cruisers....like a 47 fountain sport cruiser

If they don't exist, how do I have two hanging off my boat?

Well that`s news to me.

#7s have been around a long time. Try calling mercury customer service if there is such a thing.. next i would try calling bam...

My mistake. Never even heard of a SSM7 until now.
Me too.

From what I remember Nick there a wet-sump version of the #6 with less reduction and bigger gears and I am sure a lot of the internals are obsolete now, I would baby them with the low input speeds you have and large pitch props.

BABY them Nick..
