Jackplate Interference with Hydraulic Steering with New 25" Transom

Rybones · #1 06-24-2018, 09:09 PM

Just raised my transom to 25" on my 74 20SF. Attached new CNC jack-plate to my 1994 Erude 150 and dry fit it to transom to determine cav-plate to be 1" above straight line off hull bottom, even added 1/2" more for the 6" setback provided by the JP and marked my height and then did hole/template layout. Drilled my engine mount holes approximately 2" below new transom height,measured from bottom, got it all pretty darn perfect with engine and jack-plate mounted for height, centered and level. However, I go to mount my Hydraulic steering (SeaStar) and it doesn't fit because it needs to hang down and with the 6" setback now the JP and the top of the transom are now in the way. Yes, I could raise the JP and keep it raised to solve the problem but then i'm out of optimal deep water running height and in ultimately it just diminishes and defeats the purpose of having a JP and the versatility it was meant to provide. This is not a "why do you need a JP conversation",I'm just hoping someone has run into this before and has a fully functioning work around for this. Currently I have removed the JP and am continuing rigging without, but hope that eventually with the proper solution I can use the shiny new high-speed JP I bought 4 months ago. (because my transom was only going to take me a month..)

maybe show some pics of your issue. On a different boat I had, when I moved the motor back, the steering hit the transom and my solution was to add hydraulic steering. Do you have any pictures of the interfering parts?

Unfortunately I didn't take any pictures and I have already taken off the JP so I could move forward with the rigging and address the JP when I have a work around. When I was writing the initial post I realized the pictures would be really helpful but it was after I had already moved on.

I haven't seen where you indicated the shaft length of the motor.

Cant figure out how to post a picture Cadillac with chandeliers on front for you Dirtwheels. Just remember, girls from Atlanta will CB each other on vacation. So the new pick up line should start with "you're not from Atlanta are you?"

FYI, got my ride done, sea trial tomorrow. No jack plate for now.
