Hi all

A new member from Norway here.


I bought an old racing boat that was raced in a series called SuperVee here in Norway.

The boat was buildt here in Norway.

Not sure what the setup was back then, looks like a trimax drive or something similar.

But its been a pleasure boat the last 10 years now, and its been running with a supercharged Teague V8 and a Speedmaster 6 drive.


I bought the boat without the engine, but with the drive. The drive needs to be rebuild after it broke down. Not sure how bad it is yet.

But could somebody tell my what generation drive i have?

Tried to do some research, and from what i understand it was first the K-Drive ( Kieckhafer) , then Speedmaster 6, then 6A and then the M6?


Do i have the Speedmaster 6? And is it worth rebuilding? Can i still get parts for it? When did the drive get reverse internaly ?

Can't help
but what a great looking boat
Good luck,

Tnx! Hope this winter will be short..

But can anybody recognize my drive ?

It’s a 6

The skeg has been modified, but by the looks of it, I’m guessing it’s a wet
sum

They don’t have any shifting provisions in them,

Its wet. But do you think its a first gen?

Found the problem. A gear in the upper housing is missing half of the teeth. Where to order parts? And where to find a manual?

mercruiserparts.com

there’s a section. All else, the manuals are in there

Thanks, think i found it. But it doesnt ad up, my messed up pinion gear has 17 teeth, and the lowest option is 19? Either way, all options are "out of stock" wich im guesing means " to old and out of production " ... Any alternativs?
