I wish you had photos too! :) If memory serves you went to bigger engines. The C18's are near identical to the 12v92's, actually a smidge...
My lead guy has been doing detailed layout and mock up the last few days. The good news is the holes in the deck/engine room ovhd will not need to...
Can I not simply add some pitch to existing props? It seems like not much change from 1.66 to 1.757 but maybe I'm underestimating. No, I'm not...
I'm starting a new thread to cover the Repower of my 1994 54' Donzi (by Rosciolli) Sportfish. Today I formally placed the order for CAT C18 ACERT...
I spoke to soon on going with the 1.525:1 gear ratio. Upon closer investigation discovered the existing gears are 1.66:1 (not 1.60 as thought). So...
That's a perspective on 1(ea) 20kw and 1(ea) 9 kw that I hadn't considered. I will have to give this some more thought. I don't have room for...
I'm partial to Northern Lights. I've heard nothing but good things about them. My current set-up is a 20kw and an 8 kw. The 8kw meets most of the...
I'm repowering for the reasons mentioned. Difficulty in finding parts and service, especially for the DDEC electronics. I like the idea of getting...
What do you like about the Sturdy controls? You bring up a good point that I need to look at all the options out there. I should look at Sturdy,...
I have not looked at those or any others for that matter.
I'm getting ready to start a repower of my 54' Donzi (details covered in another thread). I'm going with CAT C-18's and ZF665-A gears. I've been...
I'm going with the ZF 665-A with 1.525:1 ratio. This is the closest ratio I can get to my current 1.6:1. I'm told at WOT at 2300 rpm the shaft...
So I have decided to move forward with the repower project. I'm finalizing some details with CAT but I'm going with the C-18's at 1150 hp (1136...
I met with CAT last week. They are working up a proposal. More when I get something..........
You are correct and I was mistaken on gear ratio. The existing gears are 1.6:1. The gears are badged Detriot then have a Twin Disc model number....
I met with CAT dealer late last week. Will see what kind of proposal they come back with. They are also going to give me some detailed drawings of...
All great info any very much appreciated. I wasn't planning on replacing shafts unless a problem is found. We pulled shafts a few years back and...
The spec sheet I have indicates the 12V-92TA dry weight is 4,895 lbs dry. Not sure where you found the 5,861 lbs you indicate? I attached the...
I appreciate all the input. It would be difficult for me to seriously consider MAN's. Not because they are not good engines but the service and...
Well fortunately I'm in the shipyard business so lots of resources at my disposal. However, we are large commercial, not yacht so a bit different.
