I am looking for some info on stern power drives. I have a pair of them on the back of a 27ft cat w/smallblocks in my shop and i have never worked on them someone has used jb weld on the upper of the port drive and I am wanting to know if anyone knows where to get parts for these things or a manual possibly.

What kind?

Arneson
Kama
BPM
Trimax

I think Stern Power is in Indy.

http://www.sternpowr.com/

This may be the company

I have a guys website saved on my other computor that seems to fool with alot of them. ( not shure but I think it is something like JTM ) I talked with him a year orso ago about some stuff. I had a 28 Pantera that had a stern powr drive on it. & yes the correct spelling is : Stern Powr if you get searching. My email address is : [email protected] Just send me an email & when I get to my other computor @ the shop I will just forward you the info from there. Talk to you later , Scott

Actually I just done a search & found his website , Hope this helps. jtmperformancemarine.com
I also have access to 2 MX-107 drives ( a Rt. & a Lt hand ) With 2 really nice Spinelli stainless props.
I also have A 19 spline 25 pitch Nibrel Lt. hand prop that I would sell.
If you are interested in any of this let me know.

i got a pair of sprt master lowers and 2 xr uppers i need to get rid of.

thanks i talked to them today and parts are availible so are manuals they are made by american propulsions systems

No problem , Glad to be able to help.

I had Sternpowr on my Sonic boat. I had the mx107. They can handle alot of horsepower, and are pretty simple to work on. parts are still available. I had a shop manual for the drives, but I gave it away with the boat. A marine mechanic shouldn't have much trouble working on it, no special tools, but you do need to order the parts and I would try to get the service manual. Props were tough to come by, but I heard they make different shafts now and hubs. Good luck
