Thank you to DC and Frank for your good advice re fitting a glass bowl CAV fuel filter to the "Seafarey" and relocating the anchor light to the highest point of the boat (Rocket Launcher)

Bought the CAV filter ($89.00) and found that you can only buy it with a filter for diesel fuel which means outlaying a further $29.00 for a petrol filter element. Anyone have a use for a CAV diesel filter element?

Another feature of the CAV filter is that the fitting connections have a hard tapered seat instead of a tapered thread that is sealed with teflon or similar tape. This means that you can only buy in line fittings instead of the right angle fittings that I need for the position of my filter. A right pain in the ar$%.

I ended up having to cut the thread off two right angle fittings and the hose connection off two of the CAV inline fittings and then silver soldering the bits together to make two right angle CAV fittings. Then I stuffed it up by not allowing the extra 1/4 turn needed to fully seat the composite fitting fully home. Ended up using some Plasti Bond on the thread to (hopefully) seal the fitting to the filter. has not leaked during tests yesterday so fingers crossed.

DC kindly supplied and fitted a small drain ball valve to the bottom of the filter to replace the screw out plastic plug that comes with the filter. Much easier and cleaner to drain any water etc via the valve into a container rather than removing the screw in plug and water/fuel going everywhere. Thanks heaps DC!

While I was at it I relocated the tank vent to just forward of the filter. That is, in a sheltered position at a high point of the outboard well. Unobtrusive and now no chance of sucking in any spray. Thanks to all who commented on this item.

I bought a new anchor light and pop rivetted the bracket for it onto the top of the Rocket Launcher. Not quite 360 degrees coverage due to the location of two of the rod holders but good enough for me and, from a distance will show as an all round light.

Ended up drilling two holes in the rear Launcher tube to run the wiring inside the tube. Fitted rubber grommets (from Jaycar Electronics, great store for that sort of thing) and sealed the join between the wiring from the fitting and the main wiring run with double thickness heat shrink tube that has glue that melts and waterproofs the join. Looks good! (have to meet DC and Frank's standards otherwise they will give me heaps)

Finally called in to Andrew Short Marine at Taren Point on Saturday morning and ordered a workshop manual so that I can service the motor myself. Whilst I am waiting for that to arrive the very helpfull service staff there gave me the info that I needed to check the idle/timing that has been a little sus so in the afternoon I used a timing light to check the adjustment.(5 degrees before TDC, top dead centre)

Found it and the idle cam position to be out far enough to affect starting but after the adjustment everything is 100% AOK! Shows the value of regular servicing.

Will post some more pics of the filter/vent/light as soon as I get a chance to pull the boat out of the garage and erect the Rocket launcher.(two screws)

Hope that I am not boring everyone to death with my continuing descriptions of the "Seafairy" mods.

Cheers

Great stuff guys, and no Haji you are not boring us with all the details of your Boat. Its great reading and inspiring to some, motivating to others.

Hey Haji maybe you can persuade that Fed chappy to fit a water seperator cause he wont bloody well listen to me :rolling laughter: :rolling laughter:

ps] how was that silver solder ????

Haji. It makes an old man happy to know someone actually takes some notice of my ramblings sometimes.
These forums are that way that a person can give advice to all that reads, but it is very rare for anyone to acknowedge they have taken the advice, thank you.

Hey Fed, DC has asked me to tell you to fit a water seperator.

The silver solder that you gave me was great DC, much appreciated.

Hey Frank what's with the old? I'm bloody older than you mate and I do not consider myself to be "old" so lay off, you are only as old as you feel!

But thanks mate,I am sure that a lot of people take notice of the advice that you, DC and others give on this site but not all are "wordsmiths". That does not stop them from appreciating good advice. (get that Fed?)

Cheers

The quality of Dog Catcher's initial advice to fit a water seperator was never in question Haji so I'm happy that you're happy.:smiile:
Have you caught any of that sneaky condensation yet?
Dog Catcher gets up to 1½ Litres a week but only if it rains.:rolling laughter:

Ended up using some Plasti Bond on the thread to (hopefully) seal the fitting to the filter. has not leaked during tests yesterday so fingers crossed.

Fix it properly mate, it will give you grey hair thinking about it.

No condensation in the old filter that I took off which did suprise me a little. I always expect to get a little over time so the glass bowl will be good. Also no blocking of the mesh in the fuel vent which was also suprising as I have previously found that over time the mesh inlets do start to clog up with salt/corrosion

I fixed the fittings with Plastibond for the simple reason that I can not undo the silver solder to turn the right angle part back a 1/4 turn, if I tried to do that it would likely wreck the whole fitting.

So the choice was to use tape which is not realley effective on a parralel thread or some form of sealant. I know that DC likes "Stag" and it is the right product for use around fuel fittings, but, I didn't have Stag so tried the Plastibond. As the filter is clearly visible I will keep an eye on the fittings and any sign of the Plastibond breaking down or leaks from a fitting and I will take it all apart again, might even use the proper in line CAV fittings with a small section of fuel hose and a hose joiner to get around the right angle problem.

Finally, you haven't been around DC's place putting a garden hose in his fuel vent (or any other) line have you? Or diamonds, copper swarf, rubber things and aluminium heat sinks. (Just kidding Fed/DC, can't help myself when I read some of the posts) :rolling laughter: :rolling laughter: :rolling laughter:

Plasti Bond is no good Haji & I'd remove it if I were you if it hasn't allready bonded the fitting to the filter.

Reason Stag is so good is because it dosen't bond nor does it go brittle & crack up & depending how much of the Plasti Bond oozed back inside the filter will determine weather those fragments end up into your motors fuel system & give you grief if the wittle internal motor fuel filter dosen't stop them.

You could've used thread tape opposed to the Stag as well preferable gas tape

I haven't seen your setup Haji but I'm pretty sure I know what you mean.
I'd be looking for a parallel thread fitting that screws into the filter as designed with the other end of the fitting being able to take a flared piece tube with a bend in it. That way the bend can be positioned which ever way you want. You need to get away from relying on the tightness of the fitting dictating the orientation of the bend. Sorta messy business eh?
Can you just run the rubber line into a straight fitting?
