In Topic: light switches

anyone found a source for small light switches?

what I mean by small is a domestic light switch is so big and one for the boat would be about 1/2 - 3/4 of the size. in brass pref




Have a look at these rated at 16 amp, measuring just 21 x 15mm and available in a variety of poles and actions. Phillippi is a German company but have provided me with mail order service as fast as UK suppliers. They will usually answer your email quickly as well.

Shepley Bridge has C&RT facilities that appeared once to belong to the adjacent marina. Saw loo's and handbasins, not sure about showers although the marina may be able to help there.

In Topic: propeller to skeg clearance

IIRC you need at least an inch or so clearance to remove the chance of nasty cavitation.


Could be wrong though, will try to find a citation

"There should be between 1" & 2" clearance between the tip of any propeller blade and the nearest obstruction. Much less than this is likely to cause cavitation.

1" on the pitch is worth about 2" on the diameter – only any use if you are trying to solve propeller matching or cavitation problems."

I understood log jam was an issue as well with clearance below what you suggest.

Apparently there can be head to block coolant issues on Kelvin "P" series engines especially if direct sea water cooling has been employed. There is an olive or seal that seats in a groove, and its corrosion of this seat that can lead to issues.

Check fuses that feed the light. If ok try and check/trace wiring from the switch (stern) end of boat.
