So I finalized some decisions and have all the big stuff now firmly on order: 2(ea) CAT C-18 ACERT @ 1150 mhp - 2(ea) ZF665A gears with 1.97:1...
So I just got my first prop recommendation from ZF. They indicate if I go with 1.97:1 then I really need to increase prop diameter as 28" is too...
These photos are old from when I bought the boat and surveyed it. All paint was removed and redone. The prop nuts are now in proper orientation....
All the furniture, cabinets, TV lift, carpet, etc have now been removed from the salon. Upon removal of the A/C valance in the ovhd of the salon...
I wanted to do this in a separate thread so as not to make my Repower thread too long. I'm starting a repower of my 54' Donzi and have determined...
We will look at all this once the boat is out of the water and in the building. That's scheduled for late this month. Right now I'm leaning...
Sorry Lew, I misunderstood a post from a few years ago.
I'm supposed to hear back today from ZF on available ratios and lead times. If I do need to change shaft size then it makes sense to go with the...
Thank you PacBlue that is really helpful. Now I just need to better understand what the safety factor really means? In other words, I realize the...
I was really hoping to keep the 2.5". I'm currently exploring 1.525:1, 1.757:1 or 1.9:1. I realize the 1.9:1 is probably best option but I'm...
Have you called Hynautic to see if they offer something? Not yet. I'm still trying to sort out gear ratio issues with ZF. I no sooner think it is...
I need power steering even if I'm only running one engine. I do long hours of slow speed trolling on one engine only. I wouldn't want to have all...
Thanks for all the great input.
The C18’s are approx. 1” shorter than the 12v92’s
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...
