    Re: Yet another square nose build

    That is some excellent info on the pole spring. So you bend both ends of the spring? The pole side is bent inward towards the coils and you put a Z or a S bend on the end which goes into the pole mount slot.

    Looking great John. That rubber door mat is a great idea.

    Fits perfect after those small bends to make the attachment points closer together. You need to do this if your running the stock hood hooks on the SN.

    Re: Yet another square nose build

    Back to making some updates after the holidays. Made the rest of the parts for the drop nozzle. Basically took a piece of aluminum angle, a few pieces of round stock, some spare bolts and copied in principle the Protec style trim system. Everything is OEM except for the Protec nozzle. Why? I like the shape and it’s straight where the GP760 is about 5 degrees up. One trick oem part is the rubber ringed 62t trim ring. That is off a rental raider. For some reason Yamaha put the extended rubber on that specific ski. One can use the GP760 rubber extended GP ring but it’s larger in diameter than the 62t or Protec nozzle.

    Overall it looks crude and rather janky. But my objective is to make the ski as cost effective as possible with best performance. The working surfaces of the pump and intake system are what’s important. I did have to buy a new Protec cable and end holder. $50 appx. I found the Protec lever on classifieds for $40 and it was new. I did NOT add a tube but rather using the oem bilge tube. Don’t want to ruin the oem dry foam! Single cooling will be plenty for my setup.

    Note: I also made a 2” Joint extension for the 1/4-28 heim joint (Blowsion HD steering cable)

    Re: Yet another square nose build

    Did a little wiring the other day. Scored a set of SJ battery cables off the web cheap so I put them in my 760 electrical box which has extremely short cables. The mod I want to show is the installation of the zeeltronic cdi. As you can see the cdi is burried in the oem 760 rubber mount but I added hvac foam on the sides and bottom of the back of the electrical box. That way the zeel can’t bounce around. I used as little as possible to prevent heat issues. The zeel is much smaller than oem. Also it’s “almost” direct plug and play. You need to add a power line from the battery side of the solenoid and a 3am fuse. Almost nobody talks about either of those points.

    The V was supposed to help break small chop. I copied it because “at the time” I liked the way the Trinity handled. However the newer hulls (Kommander) have gone to a nose similar to the blaster

    Thanks for the input. I know that rob flores fr2 race hull as a little V on the front. Never had any input about this feature and the benefits on a stand up hull.

    Re: Yet another square nose build

    Updated bilge finally and midshaft. New wsm pump wouldn’t fit but the mount was useful. I took a piece of aluminum and made a nice little bracket. The plastic wsm lower half I pop riveted to the aluminum bracket I fabricated and then 5200’d it to hull also. Put in a 95+ midshaft and newer coupler. Same old midshaft housing but that should be fine assuming everything is aligned.
