Pacific 22 / Mermaid - Page 3

I have got the the Sternpower 100 seriesmanual the Dover series operators manual and the Parts ID manuel. These have various circuit diagrams in them. I ordered got them from Mermaid at about £10 each. I am only in Truro if you did want photocopies of parts of them I could probably copy them and pass them on. I am considering re-wiring my 22 as some of the wiring looks very DIY and shoddy.

the sternpowr parts list is on the web with a blow apart parts diagram, and is downloadable in PDF, also the dover block i think. the manual is there aswell but is in norwegian! i think the website was for a company called king a/s . i will post it when i find it again.

Neville · 11 July 2004, 01:16

remember to check if your boat is a victoria marine boat or a halmatic, the wiring is different on these variations

I think this is it Neville?

http://www.kingsdiesel.no/stern.htm

The link's not quite right but still relevant, the pdf is here-

http://kingsdiesel.no/teknisk/dokumenter/15.pdf

Also in their technical section is some stuff of Ford 2700 and 2720 engines, Dorset and Dover blocks respectively, but I haven't time to download it right now - not sure what it is.

Here's a link to Mermaid Northeast (USA) site, with a servicing schedule. Says it's for Lehman, but basically the same thing. On second thoughts I'll probably get shot for saying that on a P22 thread!

My question is, are you all doing the 50hr oil change for the injector pump! This caught me totally by surprise, have talked to the engineers on here and they've never come across this either, how essential is it? It's no hassle to do it, but I haven't been doing it as I didn't know about it, and I guess the last owner probably didn't either! I know a couple of people who have the dover engine in tractors and they didn't know about it either!

Pete7 · 11 July 2004, 08:06

Oops, I thought the injector pump was supplied with oil from the engine ?

Pete

roohairy · 11 July 2004, 12:54

No it seems to be separate! Glad it's not just me. However since no-one seems to know about it maybe (fingers crossed!) it isn't too serious! Will be doing mine from now on, unless anyone knows better. Did Mermaid perhaps modify the pumps, since these oil changes are referred to in generic Ford 27xx servicing info? Anyone know?
Incidentally in the Norwegian document on the Kingsdiesel site there is a diagram identifying (I think - don't speak Norwegian!) the drain, fill and level holes on the pump.

Andy Cox · 11 July 2004, 18:14

Dunc,
I've got the same manuals you have, I'm after a wiring diagram for the boat, including the fire and engine alarm systems. Is that your 22 in the berth next to DM Marine's Avon at the Yacht Haven at Falmouth?

Neville, how can I tell if mine is a Halmatic or a Victoria, are there any easy ways of telling?

Roohairy, on my pump there is an oil feed pipe and I assumed that the pump is pressure fed with oil from the main oil system and it returns to the sump from the front of the pump and into the timing case.

Andy -

Looks like Mermaid have modified the system from standard then. Haven't even run my mermaid yet but have another engine with the same block which definitely doesn't have this mod.
Is this the pipe that comes out of the front end of the flat plate below the injector pipe unions? On the attached pic I have a threaded pipe in place of the circled bolt, is this part of the oil feed arrangement?

Seb · 11 July 2004, 19:04

Only identifying features which i have found are the logos on the disc in the centre of the steering wheel.

However, if the original wheel or steering system were to be missing, the only other way of telling would be to call Halmatic with the hull no. and ask them.

I believe that Victoria Marine are no longer in business so you wont be able to consult them!

Cheers

Most Victoria boats were made in 1990 - 91. If its a 91 boat, its probably a victoria.

On Halmatic boats the deck is screwed to plywoode member which are in turn screwed to the grp hull. On Victoria boats the deck is screwed directly to the hull.

Things like seats look similar, but are not interchangable. Some of the console panels are different, but since most are removed by the mod, yours probably wont have a console.

The layup is slightly different, with (if i remember correctly) the Halmatic boats have a natural finish inside the hull (noticable if you look under the small hatch at the front) and the Victoria boats have a grey flowcoat finish under the front hatch.

The most obvious thing that is different about them is the wiring.

With regards to the Dover block timing pump, the pump is fed with oil from the engine. There is also a pipe which links the oil feed from the engine casing to the injection pump. The fill hole is on the top next to the fuel screw. On the dorset engine, i cant remember completely, but i think there is no oil hose connecting the injection pump to the engine casing.

Remember the Dorset block is the 2700 series and the Dover is the 2720 series. The Dorset being the older less powerful block, more related to tractors and the old 'd' series lorry, the dover being common to the ford 'cargo' lorry.

roohairy · 12 July 2004, 00:15

You haven't seen the threaded pipe I described earlier in the thread then?

Sorry, meant to address this to Neville.

Andy Cox · 12 July 2004, 13:57

Roohairy

According to the Ford manual I have, the diagram that you posted, refers to the "Class 'A' and Combine Harvester Governed pump" where as the pump I have ( which they describe as the pump fitted to the Dovers ) is the "Automotive and G.P. Governed pump". The diagram referring to the latter shows a union located towards the rear of the pump on the outside and approx 1/3 of the way up from the bottom of the pump and this is described as "pressure oil feed connection", and this is where I have a braided oil hose fitted, in addition to this it also shows a plug just behind the bolt you refer to which is "oil fill plug (initial fitment only)". I can only think that you have got the Class A pump instead of the G.P. pump. This is the engine manual as supplied by Mermaid but is in essence the Ford workshop manual.

Thanks for your help Andy, I'm not at home at the moment so will have a look when I get back. I have a Dorset block in another boat and a manual for that, will need to take a closer look at the Mermaid to see what I've got.

Dunc · 14 July 2004, 16:59

Andy,
The one in the yacht haven isn't mine. Mine is landlocked on a trailor I hope to have it in the water soon.
Dunc

Andy Cox · 15 July 2004, 17:57

Dunc,

When you do get yours in the water, let me know and see if you'd be interested in a run up to Fowey or Salcombe. I'm slowly getting to grips with mine and a run in company would good for establishing reliability etc.?

Cheers

Sorry folks but the Pacific thread has come back to the top again

another epic saga

anyway for the small band of owners, been wondering what to do about boat covers for some time. Last weeks gale made the decision for me as the old one is now at the bottom of Haslar Creek and I am not spending £6 worth of air to get it back. Custom covers are about £500 which is out fo the question so ...

Spent this afternoon over with Bembridge Outboards IOW, (very busy as its the height of the season) but still very friendly people. Chose there biggest rib cover and then spent an hour trying to fit it to the Pacific. Well it just fits. If you have the standard MOD a frame it would fit much better and at £165 looks well made and a good colour to keep the temperature down underneath during the heat waves

Pete

Dunc · 17 July 2004, 20:41

Andy,
Sounds good. I'll let you know when its sorted I have a few little jobs to do before shes ready. Pete that cover looks nice. Certainly more practical than my tarp.

Neville · 18 July 2004, 00:51

Roohairy;

That diagram that you posted of the fuel pump last a page back is from a dorset block. The dover block which is more common has as i pointed out earlier an oil pipe and 2 fuel pipes going to it.

Check to see if yours is a dorset or dover , the 2 pumps are quite similar though.

On the dover , close to where you have that bolt head circled is a fuel return connection. But the dover pump does not have the 2 bolt heads - if that makes sense!

Andy Cox · 18 July 2004, 11:18

Dunc,
Likewise, I've got a few bots'n'bobs to do as well, the main thing being to re fit the gearbox which I removed a few days ago to replace the oil seal on the input shaft ( had an idea I was loosing atf. into the bellhousing ). This boat had stood still for quite a while and over the time, a bit of corrosion had formed on the input shaft and when I started using it it took the edge off the seal. Have now replaced the seal and cleaned up the shaft, so fingers crossed that has sorted it!
One other problem that I'm having is with the steering helm pump. At first I thought it was a bit of air in the system and figured that if I kept turning the wheel lock to lock I would eventually be able to work it out of the system. But the problem is persisting, the symptoms being, when I go to full lock on one side or the other and hold a bit of pressure on it, a spurt of oil is coming out of the breather hole in the filler plug as soon as I start to come back the other way. In addition to this, when travelling at speed (if that's an appropriate term to use for a P22) and I try to turn, there is a lot of resistance at the wheel which suddenly gives and out comes another spurt of oil.
Anybody got any thoughts?

Cheers
Andy
