View Full Version : Cable style trim indicator / Hydraulic steering?

01-23-2015, 07:32 PM
Has anyone done this? I have converted to the SP-A style transom and outdrive for the power trim, and would like to run the cable indicators for my drives and K planes.

Also has anyone ever set up external steering on the SP-A drives? The top cover is different than the 260-70-80-90 drives. I picked up a Manual Hynautic system, so I have the Helm, Valve, Rams, and Transom brackets, I just need to figure out how to attach them and a Tie Bar to the drives.

Mock fitting of the transom and K Planes

I powder coated the K Planes white to match the Volvo Out drives:cool:

I also polished the Reservoir, brackets, and rams from the Hynautic steering and rebuilt them as well.

Both pics that George posted are 27' Magnum sports, although the red one has some rail hardware I have not seen.

Marshall That's my red sport before I did the restoration & cleaned up the transom. I removed the very ruff looking power trim because with my drives raised 3" like Jeff's Mag in the other pic you really don't need it. Running on the second Volvo pre set pin is all I need. If I ever feel I would need trim I would put my clean set up on but as of now, no need. My sport like Jeff's never had tabs & we both feel that there really not needed, & that keeps things clean & simple in the engine bay & on the transom.
As far as the stern rails many of the sports have them in various forms. Mark

I kind of thought that it would have been obvious I was referring to murfman's pics cause everyone knows what a Mag 27 looks like :banghead:
It's just that the angle along with the small amount of boat shown + the raised deck molding had me confused.
And I thought the transom looked a little thinner than a Mag transom as well.
