Sternjack
 
Hello.

I have finally got my hands on an sternjack.
Unfortunately i have a rare hull. A Donzi 21 Hornet III.

Its gonna need alot of work to fit, so im just wondering if the forum crowd thinks it will do good?
The boat needs alot of bowlift (especially with the -2 lower) and needs to be trimmed, also, its only 21ft so its a little short in seas.. hence why i want to try it.

However I need to:
Lenghten external steering ram
Make longer studs (mayfair steering bracket)
Mill out the drive-yoke to 31mm from 27mm
Lenghten a set of trim-rams.
source an 27mm driveshaft
Paint etc etc.

I’m running a 22 classic. I would give bblades a call. He shortened a bravo prop barrel for me , much like the fs. Anyway , I don’t need a lot of trim to get the bow up. I also have a -2 imco lower.

Alreade have a bravo fs, labbed. And a hydro p5x.

However, 21 and 22 are completely different hulls.

21 hornet is "Wide beam" like 8ft Wide :)

You need the Sternjack install directions ? Probably not I guess, but I have them on my PC if you do. :)
