Clamshell telltale fitting?

9D280 · 13 November 2008, 10:46

Here we go again, another Merc question........ I must get a manual for this thing soon!

I have noticed that the telltale on my new lump dumps form absolute dead centre rear of the casing, and throws the water vertically downwards about 1" behind the leg. I assume there should be a fitting in here to throw it left or right? Either that or Merc decided that "neatness of exit" was more important than being able to see at a glance if water is actually coming out?

So, any clamshell owners out there, does your telltale come out at an angle or straight down the back of the leg? I have fitted a slightly longer hose & coiled it round to provide me with a view as a temporary measure, but if someone can verify there is or isn't supposed to be a fitting in there would be appreciated.

How big is the outlet? Some of the merc/mariners had a little push in rubber nipple that diverted the flow off to one side and reduced the outlet size to about 3mm.

Yup - that's exactly the arrangement I have. Might well be a standard spare so check with your local agent

The "big bore" hose from the top of the block reduces down to about a 3mm ID hose halfway down to the exit hole. Said hose just pokes out the hole & relies on gravity & a tie wrap to keep it there.

You've confirmed my thoughts that there should be a fitting down there...... Bizarrely I can't find a microfiche to confirm it's part number - or even it's existence!

Thanks for the quick responses, I'm off to make a phone call!

What size and year is the motor, or let me have the serial number?

If Marinautic can't come up with something and the hole your current telltale pokes out of is round there was something similar fitted to the later blueband 50s.

Nos,
Yeah, I did think a simple bit of hose poking out a hole had a hint of "emergency repair" about it..... Hole is round, I suspect had I noticed it before I got rid of the dead Yam the telltale fitting from it could have been used....

Marinautic,
Unfortuately at the moment I don't know the seirial No - I'll need to pull it out the garage to get some light behind the transom to be able to read it. (which I probably should have done before I fitted it......

) If it's any help, it's this livery: http://cgi.ebay.com/ebaymotors/70,-7...027105008r7368 , complete with mis-matched front plate! If it helps narrow down the exact year it was a transom mount Automix (that inlet is capped and by the looks of it has been running premix for a while!

) and has no thermostat (from what I have figured out so far it uses a "cold idle" calibration). Manual tilt with "outside" assist rams & a webbing strap to stop it joining you in the boat!

I may be able to get to the serial no. tonight if that isn't enough.

D'oh. Sorry. Should have stayed in bed this morning........

It's been a while since I've seen a motor of this age, but from memory the nozzle is similar to the washer jet on your car. Sort of squirts at an angle!

Part # 69555, and Barrus have 1 in stock, £5.54 plus vat!

Hope this pic explains it better.

9D280 · 13 November 2008, 15:35

Engines that age follow me around every time I go out......

Fab, thanks for that. Bizarrely the microfiches I've found online all look like that pic, but without the inset top right.

Thanks for the help. Will try the local guy up here first, failing that, I'm Phoning Barrus tomorrow!

....or lack thereof!

Took a big torch in last night - Sticker's still attatched, but unfortuantely apart form ".....URY" in the top R corner it's totally illegible, and not as I thought just too dark to read.

I can't believe they use a sticker for something as crucial as the chasis number. Is it etched or stamped somewhere else? I can't find anything obvious.

Should be on the block on a pressed in disc.
