Repowering a 54' Donzi Sportfish

Those resilient mounts under the gen are secondary. There are resilient mounts inside the cover too so it is double isolated. If memory serves Northern Lights calls them auxiliary mounts or something like that. Suppose to further reduce vibration and therefore reduce noise.

Apologies if you already addressed this point and I missed it, but why did you need to cut the aft e/r bulkhead?

It's not the E/R bulkhead, it is the aft salon bulkhead. The window opening wasn't large enough to get engines out and in so we had to make the opening taller and a bit wider.

Yes, the opening is for a Simrad NSS-12. It networks in with the other 3 on the bridge. This has been a great addition we did a few years ago. It is used mostly when we are trolling. We put it on split screen and show fish finder/depth and chart plotter. This way we can see what's happening and what's coming to work the downriggers. The bottom counters in our area change rapidly and excessively. This reduces the need to constantly yell down from the bridge.

When we originally installed it we brought the wire down through the bulkhead where there is a fairly deep void but then had to take a long route to get up to the bridge. The long cable causes it to lose signal occasionally. Now that everything is opened up we will be running a much shorter cable directly over to the port side, up the pillar, above the headliner and straight into the bridge console. The cable will now be half as long. The void between the aft bulkhead and the interior panel is something like 6" deep there. I think Donzi did this to make it easy for them so it could just be a simple flat panel inside.

I have also asked the team to see if we can fabricate and install a cable chase from the port pillar above the headliner and into the bridge console so we have future ability to run cables if desired. Nothing definitive yet but I really want to do this if we can. The stbd, aft pillar is packed with cables and steering hoses because this is the only way to get in the bridge console unless the headliner is down. I hope to never have to mess with the headliner again. I'm already nervous about getting it restored and looking good.

LOL! I sure hope this debate is over and done with. If folks want to continue it I suggest starting a dedicated thread.

You are correct Capt J - a hose is the way to go, just not sure there is enough depth here to do much good. I'll let you know what we come up with and try to get some pictures of whatever we do.

That's pretty creative. But my TV is on a lift and I keep it retracted in the cabinet whenever we are underway. It also doesn't face the cockpit and with window tint wouldn't do much good.

Lew, let me know if you want any more details or pictures on this to help you if you decide to do the same.

Finished the 9kw other than a few final dressing items. We blue fit the new Veem props to the new shafts. Pretty much a perfect fit on both the props and the couplings. It’s nice when everything is CNC machines with standard spec’d tapers. We final torqued the coupling keeper plates and safety tied the bolts.
Please, please don’t everyone start yelling about the prop nuts. This is just temporary to draw them up for the fit. We will switch the nuts around for final install.
