    1.8 bar is 35 psi, that is nice and plenty of water for cooling.
    so the big hole in the side works very good.

    Well done, you now have a great gearbox that will cut through the water better and give good water pressure.

    what was the original water pressure before any work on gearbox ?

    The nose cone came out great. What is the purpose of the spacer at the prop? Is it suppose to send the exhaust out of the holes you added to the gear case?

    Very funny.
    It's there to help a over hub prop when pulling away
    You can buy plastic ones but they fall off..
    Large holes in gear case aid in better intake for water rather than needing low water pick up.
    This bloke is getting 26psi water pressure with bullet just above bottom of transom. So it works perfect.

    that is still almost 22 psi so should still be very good.

    what pressure did you get before on normal gearcase ?

    and what propeller is that on the engine now, it looks a good one.

    ahh so you now have a bit more water pressure than with transom pick up, that is realy good. makes it a nice neat project to do.
    only problem I can see is there is no Gauze/filter material inside the large holes !!!
    I would prefer to have a gauze or filter and I have some material that would be ideal for this, would not want something like plastic bag getting sucked in the
    large water inlet and destroying water pump or stopping flow.

    I like the exhaust deflectors, they look very good, definitely a nice extra touch.

    This works like I was hoping it would. With this height dont need extra pickup. Go up from this and pressure drops a little before needle starts wondering up and down, so higher setup will need extra pickup for water.
    What comes to that ring in front of prop and those exhaust holes above A/V plate, they make takeoff really easy. Foot down, nose up, when it comes down revs go up , ease on throttle.
    VOILA' 20kn on plane, no hassle.

    so this has helped the srx get up yes ?
    it looks very very nice on the gearcase. that ring looks extra good.
    you will have to take many pictures of the ring off and with sizes so I can copy it ha ha my srx is crap for pulling away, I need the top exhaust holes and that ring.

    can you give a bit more details on what you done to your srx prop, I need to alter mine too.
    need a bit more bite from start and a bit more bow lift on full speed.
    I can do the tips to raise the rake a touch.
