Pacific 22 killswitch

Pac22 · 10 July 2006, 12:47

Hi,

I'm new to these forums, but as you may have guessed, I have a Pacific 22 with the standard Turbo 4. Eventually, the boat will be coded, but one of the first obstacles is the lack of kill switch. Presumably this works in the form of an air shut off? Any advice/tips/suggestions ver gratefully received.

Thanks

Will

Pete7 on here is your man. I seem to remember him discussing it on Priory Beach at the weekend, and his conclusion was that having tried various failed and impractical methods the best solution was to spend £50 on a solenoid from mermaid, and hook the kill switch up to that.

Don't worry, I'm sure he'll be here shortly to clarify!

Will hi and welcome to RIbnet. Have a look at this thread, I think this was the easiest way to solve it.

Although if you want to go down the flap over the turbo route I have a spare flap Neville sent me but I just don't fancy a flap stopping the air going into the turbo at high revs.

Hi Will,
I have the original flap fitted over the turbo and it is really effective so much so that I have only tested it at low revs as the engine seems to come to a complete stop instantly. Good to know if you have to use it in anger but for looking after your machinery I prefer Pete's method of a stop solenoid.

Just a thought as the flap over the intake sounds familiar:-
How about a fitment like a truck exhaust brake as well as a stop solenoid? It'll stop the engine instantly preventing 'run on' as the engine winds down from high revs.
It doesn't seem to do any harm to the engine on trucks but not sure if it's possible without a compressor on the engine to run one.

The truck the mermaid engine was fitted to (80's Ford Cargo) had one fitted as standard.

Thanks everyone for your replies. So Pete, what's on the other end of the solenoid, assuming you don't have a flap on the turbo?

Regards,

Will

Soleniod connects the to the Pump stop lever near to the pump throttle lever. The bracket from Mermaid has the holes drilled in just the right place to line the soleniod up with the lever.

Just had a look and now it's all become clear. Sorry for the dumb questions - thanks very much for your help!

for Will, Paul, Scary Des et al.

borrowed a smashed volvo long hub prop last week from Geoff at Streamlined Propellors in Aldershot. Bad news is that although the splines are the same size as a stern powr they aren't long enough so there was a gap of 1" between the rear of the stern drive and the prop. the clearance to the trim anode was also a bit tight so I am afraid its back to Lancing props which they buy in from Sillette who inport them from Eliche in Italy. Sadly its a closed shop which they won't break. The search continues.

Mine has the air intake flap for a kill switch.
Works very well.
I can see where the concern may be in relation to stopping the engine quickly, but its not as if you use it often unless you're too lazy to pull the stop lever!

On the prop front.
isn't this what we need for the P22's?

I buy all my sternpowr bits from this guy. Much cheaper than over here.
I'm sure if its not the correct prop then he can source them from the US.

These props on ebay in the USA are 18 " + 19" diameter. The P22 prop is 16 3/4 " x 21" pitch. Normally it is called an 807R. The only reason that i can think of that they are so expensive is the fact that there are probably few sold compared to volvo and mercruiser etc legs.

They can be found from time to time, this one just went tonight on ebay!

The 18" + 19" props are for the 103 and 113 series legs, so be careful as they wont fit a standard P22 (101) leg. Likewise some of the parts in the USA on ebay, it doesnt quite feel as much as a bargain when you pay as much again to get then posted and they dont fit. duh..... its a long way to send them back!
