Radar Arches And While We're About It

Can anyone help me with a local company or indivudual who can supply me with a radar arch (stainless) approx 4' long for my Hardy 20 ?

 

Secondly last year someone nicked my prop for my Yamaha 70 (3 cylinder 2 stroke PTTL) I originally replaced it with a 15" pitch but the engine will only rev to 4200 (red lines at 5500) and will only do 12-13 knotts (before the prop was nicked it would carry three gorillas fully loaded and would idle all day on 4000 revs and hit 14 knotts on the plane).

 

I am therefore going to change the prop to a 13" diameter x 13" prop as recommended by Hardy for the use of this model whilst using the Yamaha outboard. I realise that changing the prop down is never going to allow me access to 5500 revs but I'm worred that if I reduce the ptich further all I'm going to do is make souffle's.

 

Any advice or opinions would be greatfully received.

 

You have to understand that the use of my boat is purely for the purposes of fishing I don't profess to be an expert on the mechanics, in the words of Oddball, "I only drive them, I don't know what makes them work."

Go to online store, then to Stainless Steel Seck Fittings - here you will find Radar arches like this:

 

Basically for every 1" you reduce the pitch you should gain about 200 rpm - so this may help - I would recommend speaking to Prop Revolutions @ Cobbs Quay, tell them you engine, boat and revs etc and they will put you right.
