05 SJ surf/free reinforce/build-up (now with completed pix, page 3)

Thought i'd post some info on my jetski reinforcing/build thread. I don't have all the pics available yet, but i'll add them when they are available...

This is how the hull looked returned from the dealers. They are giving me $200 for materials and pulling the motor out for me under warranty. I did not trust them to do the labor on the hull build. At this point, the kickers have been installed, but the pictures are elsewhere...

With the remaining parts stripped out.
2-1.jpg


sanding the hull to remove mold release and promote adhesion
3-1.jpg


filling in bondline, under handpole bracket and nose with foam...
4-1.jpg


cutting a hole for a scupper valve to be installed.
5-1.jpg


The foam is sanded out so that just the negative space is filled. This is mostly along the bond line and under the handlepole mount (this allows a piece of glass to join the handlepole to the sides n one straight shot)
6-1.jpg


Measuring up the glass. There are 3 layers here of increasing width. This section will bond the entire top to the entire bottom and strengthen the entire craft... It is common for the craft to break on the sides. We used 16oz biaxial cloth.
7-1.jpg


Starting to lay the resin. It's a 2 part thin epoxy with a fast cure ratio. 4:1 mix.
8-1.jpg


This looks so slutty. It was a ********ing mess. You need to squeegie the ******** out of the glass to get all the air bubbles out. It's not easy, i got better as we progressed... The strength doesn't really come from epoxy, it comes from the glass.

Other side. This is the thinnest strip
10.jpg


Medium width strip
11.jpg


Widest strip. It goes from the edge of the hood lip all the way to the inboard edge of the motor mounts. You can see the 2 part foam through the glass on the bond line. The idea is to make a strong beam shape with a high moment of inertia.
12.jpg


Another shot of the boat on it's side. Here you can also see the unreinforced bulkhead. This is the area where the boat was breaking and will require the most care. you can also see the 2" hole we drilled for the scupper valve tube.
13.jpg


The bulkhead reinforcement. there are two layers here (you can see the line of the bottom layer) with two additional strips on the sides. This ties the bulkhead deeply into the floor.
14.jpg


Measuring glass for the nose... My nose was already smashed pretty good from hitting bottom, so it needed much attention... We loaded the seam with 5 minute epoxy then glassed over it.
15.jpg


The nose finished. We used 3 layers here of 16oz cloth
16.jpg


Measuring up the glass for the inside. 2 layers in the nose (tho in final install the smaller piece is underneath). 2 layers under the handploe. The handlepole reinforcement also grabs the hood lip corners, another common cracking spot.
17.jpg


The nose and handlepole done.
18.jpg



I also reinforced the rear hood corners and the hood latch mounting location. (above the bulkhead) but don't have any pics...


Now we have to finish installing the scupper, install the aftermarket parts and motor and go do some flips...

wow, that looks great. good work! you said the stealership gave you $200 for parts? how did you swing that!? nice!

yamaha said they would warranty the crack in my hull.

Well, they would fund a repair job... I didn't trust the dealer to do it properly, so i had them do all the mechanical work to save me some trouble...

i also have a bunch of aftermarket parts to install...

Nice job!!!! When you getting the motor back from Jimmy?

If this thing hold together for more than a week, I'm gonna get some ride time on it right? I've gotta see how an over 10K SJ compares with and over 10K SXR. LOL It should be a great fall!!

Serioulsy, though it's coming out great, except for where my hacked up fiberglass skills came in to play.

Lets Ride!!

I have no clue what is in yours, as far as real money goes. I know on his, and mine, so they should be pretty even soon. I want to see how they compare, maybe a future Consumer Reports/Blowsion build up test. Flat water and surf conditions.

I had to throw the surf in there for me, I don't stand a chance in flat water! LOL

Looks sweet man.

Is it a scooper valve or scupper?



the Loti is a much more important project.

The ski should be the more important project. I hardly ever work on my car any more. I would rather spend my money on a hobby that
a) costs less than a car when you break parts
b) aftermarket parts cost less
c) no speeding ticket on my ski ( just some tickets sometimes for riding too close to shore)
d) Less of a chance of killing yourself in the water than on the asphalt

The re enforcing looks great. I have already subscribed to this thread. I know it will come in handy when I got to reinforce this winter.

i notice you used foam
wouldnt it have been stronger to use resien paste
ie with micro ballons in it or is the foam strong enough
 

hangtime

Speak up ,don't kiss azz
I think using foam on the bondline is not good also .Foam has no strength .Ii realize it's just for smoothing out the surface for a better bond with the cloth but Marine bondo or resin would do the same thing and add strength as well.:biggthumpup:
