    Guys after replaced the motor mount we did noticed some minor flex (torsion) in the hull but definetely nothing serious to get in trouble,that video is with the flex motor mount and the boat ran very smooth I can testify that no reinforcements are needed. Gill

    Thanks guys and yes Chris this is our place for heat and saw running despite the low water's level but with the begining of spring and summer coming up we will have the necessary rains to raise water. I would like to mention that we decided to swap the rigid motor mount for a flex one with very few mods,the rest remains original. Gill

    OPS Collectors

    I'm trying to find an italian article in the bibliografy I have collected over the last thirty five years where they mentioned a round nose boat equipped with this engine hit 180km/h...hope to have more time to post it! In the 70's we used to run our OPS's with those Perry's carburetors to solve the problem of the needles breaking under vibration on the ops carbs. Gill

    Agreed Timwhalen we also were lucky with Picco's rods but the RPM's were nice products and their rods very good. Thanks Gill

    Thanks David yes for the very first tank after 25 years I think my friend is pretty happy to see his toy working.The lake is in a private club good enough for testing but we use to race in another site . Gill

    Today we finally could send the boat to water and for its maiden I think everything worked good.The Sg turnfin keeps the boat on rails and despite the small prop used for the break in I think this beauty has more to offer so more tests will happen soon.As the owner is very conservative about high percentage of nitro the boat was tested using only 20% nitro fuel and I can say he's happy for the moment.We hope to finish the break in in the next weeks if weather helps and test better props.Gill https://youtu.be/C1FSOxGtBZA

    Bradley you are right I also couldn't find any good video but tomorrow I hope to get a good one.David 20 years of storage in the tropics can be tough on brass...look at the nipples and carb fortunetely nothing serious and today we already test the engine and I guess this boat will turn heads at the lake. Thanks Gill

    Carbon fiber radio interference?

    The only issue I have found with my CF riggers is GPS do not work at all. Gill
