Pitot tube???

Hi fellars
We have just picked up our new (2nd hand) Avon 560 from JBT and for some reason the pitot link to the helm is not connected to the outboard, does anyone know where it connects on a Honda 115?

Sorry I can't help on your Honda, and I am not quite sure what you mean by pitot link, but I am enjoying my second season with my 560, so I may be able to help with any questions on the boat.

Do you mean the tube that measures speed?

if its a four stroke, the manuals can be found here Honda BF115 Outboard Engine - 115 hp boat motor specs and features

just look up your serial number. the pitot is probably going to be on the upper unit, as i understand the modern hondas have the pitot from the lower unit integrated into the casing to protect it. I might be making that up though!

Most engines with the built in pitot will have a short length of hose with a blanking plug hiding somewhere under the front between the tiller & the casing.

As 9D280 said, it should run up the front of the leg, rubber hose, normally a bit thicker than 1/4", may have a plastic plug if not connected, or may be a continuous run up to the console with the wiring harness (if connected.)

These things are notorious for plugging up with bits of sand, shell, seaweed, or dried salt. I(f you don't see a plugged hose on the front of the leg, take a small stiff piece of wire and clear the hole on the LU's leading edge (may have to run a thumbnail along the front to find it - they hide pretty good.)

and I also forgot to mention that you are usuallty better running with an OEM gauge of the same as the engine - I've read on t'net the Teleflex gauge reads something like 10% down due to the hydrodynamics of the leading edge of the O/B leg (which of course will be different for every engine) & the Teleflex pitot sender.
