Back From the Dead - Yamaha FX-2

I got cabin fever and cut my rails… I probably should have done this when I built my rails up initially, but I don’t think it really matters that much. The rails will be thicker than they would have, but I don’t mind. I thought about this for a long time and decided that the wide rails around the nose would try to plow through a wake or wave VS moving the rail up, and allowing the rocker of the ski to lift the front end. I am going to cut slits in the rail vertically to allow it to follow the rocker of the hull itself. Maybe I’m crazy but it had to be done! Does anyone have a suggestion on how close the cuts should be together to allow the rails to flex up properly? I was thinking each 2” or so…

Turn that frown, upside down.

I filled in my bow eye with expanding foam. I used tape on the outside and poured the foam in. Came out real nice!



After that I taped the bond seam from the inside with tape so I could lay some glass on the outside.




I decided to sand down the keel a bit and then added another strip and wrapped it up around the nose of the ski.




I had to figure out a way to fill the void behind where the the rail was going to be, so I used some tape to make a template

I used the template I made to fill the gap behind the rail.



I filled that gap with strips of 1208 and then some thickened epoxy.



Laid up several layers of 9oz cloth and she is looking right!

What are you doing here?

Looks like he wants it to push a lot of water up into his face like all the aftermarket hulls do.

Not an answer

How would doubling the size of your front rail push water up into your face? I would have to agree that hulls with no bond rail in front are terrible for that.

Dude that thing is broke down more than McDonald's ice cream machine. No.

Hey now...............

The idea was that because I made my rails wider, and deeper, that new rail is covering part of the nose of the ski that wasn't intended to be covered. I believe with the rail pulled upward and not totally flat, it would then expose more of the nose/rocker of the ski and would not allow the front end to dive or stab into a wave as easy. I think it would help reduce pearling. I also think that if the rails are rocker as such, when the hit water in a trough before a wake or wave, the rocker rail will help lift or at least direct my front end UP, and not forward through a wake. Maybe i'm wrong... Too late now



I removed the straps and the rail feels very strong. I removed the tape from underneath the rails and it got great penetration through the glass! Im within my 24hr epoxy window so Im about to reinforce from underneath the rail to give it some strength. I have been using a digital scale to weigh my epoxy when mixing it, this has allowed me to get an idea of how much weight im adding + fiberglass. Before I did this rail rocker, my ski weighed 74.6 pounds without the hood or cooling lines/exhaust. I think im still in a very good place with weight. The epoxy and glass it took to reinforce the rail was less than a pound. I want the ski to be light, but I want it to be strong. If I never end up getting something aftermarket, I need this to last!

 

[brapperdoodle]

Holy cow, these rails are solid!




Apparently there was a void in between the inner and outer layers of my rails, I sanded down the outer layer because I was adding the reinforcement for the nose. But it exposed some pockets I will need to fill, no big deal because I’m going to turf the rails anyway!

 

[Sanoman]

You may be on to something here! Looks interesting

 

[Stavissimo]

Looks so good, wish I could do this to my fx1 haha

 

[fastgtfairlane]

Looks great love the rocker. Looks really smooth and clean. Only thing different I'd do is cut the bond rail a little shorter on the nose so the rails look uniform all the way around

I finally started gluing in my through-hull stuff, I even sealed up the bulkhead for good measure! Goopy McGooperson

What are you gonna foam with?

 

[brapperdoodle]

Pink foam from HD. I still have 2 huge blocks of EPP foam but I never used it because it would be insane to try and cut. I also still have the stock nose foam that I will be putting back in and stuff the engine bay with pool noodles. I like floatation, it makes sense to me.

Whatever floats your boat!!!!!!!!!!!!!!!!!! LOL

 

[brapperdoodle]

Filled the nose bond line with thickened epoxy and laid 1 layer of 1208 biax on it. The bow eye got a piece of cloth over it that overlaps with the side pieces. This will be where my U bolt will go through. Came out great!



Also got my cooling lines and trim tube squished in
