Hey guys
Has anyone pulled the tank on an 89 Tristar Sport
have looked and see that the observer seat frame is part of the top deck but is screwed down.
I can see the sections of Floor forward but cannot see how you get them up.
without cutting the frame of the observer seat
Surely this can't be
Anyone have any ideas?

I'b interested if anyone has experience with this also. I kinda think they must have put the gas tank in before the top of the boat was attached to the hull. What is wrong with your tank?

I think you would need to split the hull to access the entire tank, but I'm not positive.

Can you post a few photos of where the removable panel is under anything that could make this difficult?

Why do you need to remove the tank?

thanks for the replies
Picked the boat up last weekend as a dooer upper got it for a good price
the guy who owned it had pulled the pipes and was using 2 Outboard cans upfront.
I originally was running on LPG and the previous owner had used the Gas tank as a ballast tank.
all i wanted to do was check if it was ok,
I was blown away when i saw how the top was slapped on top of it
this is my second M/C
I think i may just pull the sender and fill it with water and see if it leeks
then suck it all out?
Not unless anyone has any good ideas
I Love the look of this boat i want it looking back to factory
watch this space

Good luck with your project. We have had our Tristar for 15 years and have had a lot of fun times in it. It is a good looking boat for being 25 years old, and there can't be too many of them in jolly olde England! It seems like the front end would be too heavy with the tank full and extra weight up there. I already have trouble with waves coming over the bow if I'm not careful.
I think your right about just testing the tank for leaks as there really isn't a good way to remove it.

Hmmm... You'd have to remove the front panel (easy, just screwed down). To remove the middle panel, you'd have to first remove the pylon (probably stuck pretty good), then lift and shift the floor panel while prying up on the seat base, (probably have to remove the driver seat as well) not so easy, but can be done. I took a few measurements as follows. The bilge is 26" wide, tank is 24" wide, and fairly long, the opening in the fixed passenger seat is 28" wide. It seems like you could lift the front of the tank up and push it all the way forward and up, then lift and shift the rear of the tank over to the seat opening and slide it out by pulling it backwards through the opening. BTW, the tank has four alum. clip angles screwed to the side of the bilge that kind of hold the tank down.
Now that is just a theory, I've not actually done it. :D
You'd definitely would want the tank as empty as possible. I had all of it apart while recarpeting, but the tank remained in place. A couple of pics that might help. The driver seat in the first one is just sitting there, it is unbolted from floor. Let us know if you attempt it. Good luck.
