P22 missing parts

Hi there,

Would very much appreciate some help from the P22 owners out there in identifying some parts that are missing from my boat.

Engine box rear:

There is a large hold (approx the same size as the exhaust) which has at some point had a fitting around it as there are 6 screw holes. There is nothing connected to this and i cannot see its purpose. Any ideas?

2 x holes next to each other just above the deck level approx 50mm diameter.
Again, not connected to anything. Purpose?

To the left of the large hole, 1 x metal vent fitting with an internal inch tube to attach a pipe of some sort to. Purpose?

2x wooden mounts that appear to be made to have a rod of some sort stored between them. Purpose? (similar but larger than the dipstick holder).

4 x holes arranged in a square shape (length of side approx 200mm). Internal metal fixings. ideas?

Engine box starboard

There are 4x large bolts in the side of the box towards the aft that are not holding anything. Should there be an original fitting here?

Engine box lid

Aft of the porthole there is a brass fitting which has a missing cap and is therefore only an open hole. What is the purpose of this?

Instrument panel

Should there be some sort of protective cover for this a there are
missing fixing all of the way around it?

Console side starboard

3x power sockets. The two upper are 'NUC light socket' and 'special ops light socket'. The lower ones label/plaque is missing. What should this read?

Any help/advice would be very much appreciated.

Cheers,

SEB

Seb, The big hole on the back of the cover with the screws round it is to take the bilge pump. Its a henderson MK V pump. The bits of wood sticking out are the bracket for the holding the lever for operating the pump when not in use. The two large holes that you also talk about are for the bilge pump pipes.

The chrome vent on the back vents the engine (if i remember correctly) , and goes to a box in the sump on some models). The round fitting on the top of the cover near that 'porthole' is a fire extinguisher injection point.

There is a protective shroud for the console. This gets eaten by the sun and falls apart quickly. You could have something simple made up by a local sailmakers. The label on the side of the console should read 'charging socket' which is of course 24volts. If you dont own a 24 volt charger its quite useless as with some of the other electrics in the console.

Pete, with a 23" pitch on the back we got 29 knots last week. This was with 165 hp, half a tank of fuel and 2 people. Acceleration wasnt good and I dont thonk that the engine quite reached wot. Also we hadnt pumped out the bilges and I think there could have been a little weight down there. I think the best alrounder prop for 165 hp is 22" which got us 27 knots. Also our boat would have been a bit lighter than yours not carrying the liferaft.

P22 missing parts

Brilliant! Thanks a million- will save me messing about trying to find parts that look like they should belong there!

Any ideas about the fire system? Is there suppost to be a detector in the engine box? If so, do you know where i can get one from?

Cheers again,

SEB

Oh, did you ever get a pic of the a-frame that you were having made?

Seb, There is a fire detector ('Firemaster') on most MOD p22s, the system is in the console and they are normally mounted directly in line with the round henderson hatch on the side. The system sounds an alarm, switches on a light and shuts the engine down.

The setup is quite expensive, and I think its a bit of a waste of time. The engine bay has to get quite hot to set it off, by that time quite alot of damage would have been done. Next, it normally shuts the engine down. Well that really screws you up cos not only is the boat on fire, its stopped, and once you have put the fire out, the electrics will be toasted so you might not start it again.

A good idea on petrols but not diesels where diesel fuel does not ignite very easily.

Probably the best way would be to install a couple of automatic extinguishers in the engine bay. The one problem with not switching the engine off is that the intake of the engine running can deplete the extinguishing agent, but I think I would prefer to be in control.

Ive not managed to send you that photo because my camera has packed up. Get it back this week....

Nev, copy of the wiring diagram e mailed to you this morning and the hard copy is in the post.

If you want to sell the 23" prop I would be interested in it. Could you bring it down to Weymouth ?

P22 missing parts

Cheers for that!

However, the firemaster and alarm are still fitted inside the console and seem to be perfectly in tact.

I have traced a wire from this system into the engine bay and it has been cut off so i assume that the actual detector doesnt work! (although the alarm keeps going off and a light says 'fault') but i think this is because the instrument panel is in bit and is shorting somewhere?

Is there just a basic smoke detector that will connect to the cable in the engine bay and if so, assuming that all of the other electrics in the system work properly, will it work? - or are there more parts that i will need?

It seems pointless having half a system there that doesnt work so i may as well get it going!

Cheers for the help again.

Look forward to hearing from you.

SEB

Seb, the ones that we have seen are fire detectors rather than smoke detectors. At the end of the day it will still basically just open or close the circuit going to the alarm. Probably better buying the sensor from the makers of the fire system or ripping the rest out. The sensor is located about 18" directly below the hole for the bilge pump. It is a grey box with a 3 inch long small round thingy pointing forward out of it. You never know, could be worth phoning the makers of the system (not Halmatic though) as it may be cheap enough to buy. On the other hand....!

Pete, sorry about that prop, it cost 300 and is on a customers boat now!

I do know of a dealer in sternpowr bits who has a few standard 16 3/4 x 21 navy props for 200 each. (SR Marine, Mermaid Marine agent). I will however not renege on that deal with the whisky though! May see you at the weekend.

Nev, who is SR Marine, just had to pay 300 to Lancing after I crunched a prop in Portland Harbour.

The stern power drives are great at removing lobster pot markers though, took two out during the week which were invisable.

Don't worry about the wiskey can't stand the stuff. However the girlfriend loves the shortcut biscuits you have up North. A box would be worth loads of brownie points.

Pete

SR Marine are in Plymouth, 'Stan Gillam'. He has alot of sternpowr parts, and knows the drives inside out as he used to recon them for the MOD. He has new ones for 200, I think they are all 16 3/4 x 21 though. His mobile is 07836 637415. Office 01752 815050.

Got the paperwork through from you. Thanks a million, I had most of it but was missing an important part of the ignition circuit on our manual. Also the C of G detail was interesting (well for squares like me it is interesting!).

Biscuits will be down this week. I am on the south coast at the moment delivering a boat, but am heading back up north on sunday or I would have looked you up....
