    Need help!

    That would be 838kv, their is no way a motor of that size would be anywhere even close to 8380kv.

    best solder

    Are you using 60/40 or 63/37 solder ? 63/37 flows better in the joint, 60/40 does not flow as good & can result in cold joints. 60/40 is best suited to plumbing.

    Any knowledgeable Picco historians?

    Gualtiero Picco was also the designer for OPS in the late 60s & 70s before he started Picco Motori, the P in OPS stood for Picco. I had one of the first OPS 60 motors around 1968 or 1969, this was a ringed motor pre ABC versions. Front exhaust with Zimmerman valve that came with a tuned pipe.

    Only thing changed on the stock Geico 36 boat was a set of ABC propellers prepped by Chris @ Dasboats.

    horizon zelos 36 cat

    The new motors in the Geico 36 are more power full & larger 3674 - 1900kv motors than the Zelos 36 smaller 2000kv motors. The outdrives are also longer on the Geico 36, the new boat is much faster than the Zelos. Around 95mph has been done with a stock Geico 36 with just prop changes from Dasboata.

    Thoughts on AxeRossi glow plugs

    Axe Rossi were the old original Rossi company, when the 2 Rossi brothers split around 1984 one went on to form Nova Rossi. Who are still trading as we know, i understand Axe Rossi which was run by the other Rossi's son shut up shop in the last few years.

    Balance point on mono?

    A good starting point for the cg on a mono is 30% from the transom, around 7 1/4" on a 24" boat.

    A/A 45 Titanium Rod

    Al on a different note, I understand that Axe Rossi made the A/A motors for you. Just out of interest Axe Rossi seem to have disappeared off the face of the earth. Do you know what has happened to them as a company, im not after any of their products but just curious after them being around for...

    Prop re-pitching and casting.

    I used to have the forerunner to your Super 11 the Emco V10 P lathe ( great lathe ) for around 21 years ( 1994 - 2015 ) . This was a 1977 machine but had a gear in the headstock explode causing terminal damage inside the headstock ( simply not viable to repair on an old machine with parts so...

    Prop re-pitching and casting.

    When you say 0.025" cuts do you mean taking 0.025" off the diameter or radius, in the UK their are still lots of quality made accessories still available for the C5 still made in Austria but I understand these are made by another company for Emco Hobby machines . When I was in hospital in the...

    Prop re-pitching and casting.

    Terry I notice you have an Emco Compact 5 lathe along with the Emco Super 11, can I ask your opinion on the little Compact 5. Re its accuracy & general ability on smallish work, do you get much chatter generally from the machine considering that it also uses plain ballraces on the headstock...
