Small refit Merry Fisher 805

njrs_123 said:
Evening Jake, hope the refit is going well? I’m really enjoying following your journey and as I mentioned previously, you have provided a wealth of information that continues to aid me with my own 805, and for that I am truly grateful. With that in mind, I was hoping I could pose another question and ask a couple of polite requests?

Firstly, I’m looking to order some Roca W12 Wiper Motors and wanted to check whether you fitted the 42mm or 68mm bulkhead version? Also, can I ask, did you fit Roca Pantograph Wiper Arms for 72 Spline Shaft (454mm-591mm), and if so, what size wiper blades did you fit? Were they 405mm?

Secondly, now that you have fitted the solar panels, would you be able to share some images and detail of how you attached them, location, connectivity etc?

Lastly, you had mentioned in an older post about the possibility of sharing a wiring diagram of your new installation. Is that still possible, given you clearly have a lot more knowledge than me and I’m really interested in learning more about what you fitted and how you wired things together. Of particular interest is the Victron equipment.

As always. appreciate all your help and thanks in advance.

Hey

Yes I will update this thread again soon, working on upholstery and vinyl wrapping atm

For the wiper yes you want the 68mm version. I tried the 42mm version first and it didn’t fit. Well it did fit but then I realised it has to sit at an angle and it’s then not long enough.

Then you want the biggest panto arms for the W12s and 560mm wipers. Any longer doesn’t really fit and also the motors will struggle to swing them. 405mm wipers will be too short.

Here’s some links I got for someone else

These wipers: Roca 12 Volt Window Wiper Motor W12

These arms: Roca Pantograph Windscreen Wiper Arm

And these blades: Roca 560mm Window Wiper Blade and Adaptors

It's not exactly a straight swap, have to do some fibreglass work, see here: Small refit Merry Fisher 805

I also really recommend getting one of these, they work brilliantly Amazon.co.uk

You will have to pull some extra wires through the ceiling but that’s easy.

I forgot to take photos of solar panels so far but they are 2x200W semi flexible panels going sideways.

Cable goes in through a gland I 3D printed and then down the rear pillar and into the battery compartment. You can access the area by taking one of the factory fit speakers out.

On the wiring diagram yes, just need to make it into a shareable format. Will do that soon.
 
Been doing bits and bobs

Started thinking about a bracket for the radar but thinning about it is as far as I’ve got so far.



Don’t think the previous owner had changed the fuel filter for a while


Gave the diesel tank one last clean out


Prepped for installing the new through hulls


Fitted the through hulls




Fitted a new anchor light


Did some melting on the fuel tank to fill old holes


Started on some vinyl wrapping


Looks good to me


Made a gasket for the fuel tank



Fitted the fuel tank fittings. Used Hylomar to try and seal it up, really don’t want it to leak. Worried about the Eberspacher pickup but we shall see.


New sensor


Worktop on


Did some reinforcing on this join to stop the floor squeaking.




These outer blocks will be removed after the glue sets

Have you done a budget for your project?.....it looks like it was done without any financial restraints.....and if we include your labour 🤔

Not really added it up or tracked it. But it's somewhere in the region of 10k or so. Maybe closer to 15 but that includes a bunch of navigation stuff I could easily remove (ultrasonic wind sensor etc). I’ve been thrifty with buying stuff for it off eBay collecting it over time. Autopilot came second hand from a chap on here.

Ive obviously got access to a lot of tools and equipment through my business that’s made it easier / saved money.

I paid 31k for the boat in 2023 which I think was a good deal in hindsight. 805s in the UK still seem to be advertised for 35 to 40k.

It’s hard to know what it’s worth if I was to sell it now. My theory is if you buy a popular / well liked boat in the first place for the right price and do a good job of a refit you will generally get your money back (excluding any labour) and it will sell easily. That was the case with my previous rib.

But I’ve not done it to make a financial return:

a) it’s an escape for me from work
b) it’s the perfect boat for my use now

I wanted a boat with:

- diesel inboard engine (because petrol is a pain to buy / transport
- single engine on shaft (twins on small boats just seems nightmare to service)
- ability to dry out
- no canvas or fly bridge
- plenty of lounging space
- plenty of space for electronic toys
- trawler speeds rather than planing
- a modern ish look

… and I wanted it all to be basically brand new because I hate old / broken stuff that constantly needs fixing.

Without spending a huge amount more money this was about my only option.

Did some more vinyl wrapping




 
The vinyl wrap looks like the same as we used on the cabin overhead on Casper, our last boat, it was a dark "wood" panelling before and the lighter wrap really made the small space open up, so much brighter in the cabin afterwards.

Yep, this is CoverStyl H10
Slats Patina H10: Architectural Vinyl Wrap for Renovation - Coverstyl

I was a bit apprehensive about wrapping the original woodwork but it was basically lacquered plywood and it would have been an enormous amount of work to restore it to original condition. And once I had done that it would still look like something from the 1970s.

The vinyl wrap is literally transformational and you would be hard pressed to know it’s been wrapped. It also means I can just fill all the holes / bodges previous owners have done rather than having to replace whole panels.

If it’s good enough for Setag I figure it’s good enough for me…
 
That's what the ceiling on Casper was too, just a thin veneer over 2mm ply, taking the ceiling down was going to be a big job in that I would have to remove the large hatch and then try and get it out from above the partitions, so I just wrapped it. I think it was distressed light oak was the pattern.
The folk that bought the boat liked it, so it was a good choice ;)
 
Great wrap work!

I’ve found a new sort of wrap. Architectural wrap used in lifts and alike. Super thick and hard to work with but epic stuff

Oh…and paint on fabric dye for soft furnishings…love it! 🤣🤣

Going to do something different with the doors but not sure what just yet

What “paint on fabric dye” do you recommend?

I spent £60+ on TRG spray dye to do an old v-shaped vinyl sun-bathing bow cushion (1800mm x 1400mm at max points) and coverage was terrible and it very tacky despite me leaving ample time between coats.
 
Test fitted the curtains to measure the triangle bits



Perhaps should have used a liner, can do that later maybe. Be fine when it’s less bright.



Mounted the heater control panel


Bought a new antenna for the AIS off eBay, previous owner had bodged it.

Printed some special brackets



I wanted to mount the antennas as high as possible in the ‘brow’ of the cabin over the windscreen. That way they are mounted in a good location but it doesn’t look like starship enterprise from the outside.


Did one for the Garmin GPS24XD as well, maybe over engineered it





Seemed to work really well


Then designed this funny looking thing to tee the windscreen demisyer vents into the eberspacher. Printed it in ABS so should be ok with the heat.


Need to see if it fits tomorrow


Sent my colleague into the engine bay to change the oil pressure sensor, thought we were going to need to make a special spanner but we managed it with just a standard stubby spanner.


Gave the engine bay a bath


No idea what happened to the old sensor, it was working fine when the boat came out of the water but now it’s massively high resistance. New sensor works perfectly though and oil pressure straight up.

I put a bit of red hylomar on the thread, not sure if that was wise or not.

 
Transport is now booked for the 28th August to go back in the water so pressure is on.

Fitted the VHF antenna, Shakespeare Quickfit one that can be unscrewed.



I fitted a big plywood backing plate behind it to screw into.


8 foot antenna


Sorted some wiring out


Got rid of the rust stains in the roof from previous owners tractor spotlights that rusted


Put packers in the fridge compartment so I could screw the fridge in



Fitted solar panels on the roof


3D printed these things to let the cable in




The connections conveniently hang down behind the speaker


Put a block in to support the wiring harness in the wall. Fitted some switches


Took the fuel filler out to reseal. Also revealed all the railings on the roof but forgot to take photos.


Eventually wrestled the fuel tank back in, had to remove all the fittings again.


Replaced the fuel tank breather


Some utter idiot had tried to seal it with ptfe tape??!!! What is wrong with people ffs


New one in


To be continued…
 
Woke the old lady up, couldn't be bothered to swap the beater vice out





Made up this ali plate to mount the steering cylinder, the dro on the mill made it easy





Got these made up earlier in the week


I lost the original trims that went on the windows


Had to scribe them in


That'll do


You won't be able to see the bit at the bottom once it's painted black


Then bolted the plate in


Thought I was finished with the steering


Epoxy primered the window trims



Then 2 packed them


Then realised I forgot about the rudder sensor ffs, stared at it for about an hour before coming up with this plan


Mounted this


Then made a turret spacer thing for the rudder sensor itself to bring it to about the same level




Then started mounting the fuel transfer pump, the boat lives on a swinging mooring and often has to be filled from cans. So with this I will just have a wonder hose that I can stick into a can and suck it up like a digger does



Decided to mount it on the ceiling and used the bolts that stuck through from the flybridge ladder to hold it up so it's easily removable.


It will be something like this
 
Decided I better paint the pump to try to stop it from corroding too much


Hopefully the 2k will stick, was nightmare wiping silicon off


Did the ends of the suction hose


Gave the trims a quick whizz over with the polisher


Then fitted them but that was such an annoying job forgot to take any photos


Decided to replace this silly plastic fuel tube with proper stuff. The Planar / Autoterm kit really was utter junk. The heater is fine but everything else they supplied should have gone straight in the bin.


Plumbed up the fuel tank


Don’t have the correct jubilee clips to finish the heater. The junk that came with the kit was zinc not stainless.

You can see the contraption I came up with for the rudder sensor.


Shortened the exhaust, multitool is quite good at cutting it.


Fitted some hoop things


Then strapped the exhaust in. I think the factory used cable ties but that seemed pathetic.








It’s coming together now. Think just about everything externally / in the bilge is done other than a polish. Just the internal stuff to finish this week.



 
Absolute top draw work there. Proper attention to detail! She looks stunning and can’t wait for the finished article

Thanks, I somewhat regret ever starting it having spent the best part of 2 years doing it! Been a proper test of willpower.

Replacing every mechanical, electrical and plumbing system with new was way more work than I estimated.

I’m looking forward to spending 2026 afloat rather than in a car park 🛥️
