Thanks I appreciate it I am still Ironing out what I want to do but it will be decision time soon on this part of it.  I am storing the extra plywood in the wifes minivan, it stays dry in there and its part of my plan to allow her to let me keep working on it so she can get her van emptied back out.

Looks like a pretty good-sized tank. Having that much weight in the wrong place may affect the handling I would think. Too far forward, too far back, etc... Just thinking out loud.

Old tank was 26 gallons just set on top of the floor under the deck in the bow.  This tank is a 30 gal tank.  I have heard moving the weight to the back in a jet boat helps plus then don't need to run such a long fuel line.

Dman yeah I have been rolling that around in my head for a while now but if i had posted it here would have gotten jumped for thinking about that before any other progress was made.  I had thought about taking the stock tank and recessing it into the floor as well.  All food for thought just trying to figure it out.

Kona the engineers I guess didn't plan for this boat to be around 40 years later cause it was horrible implementation of the build with all the wood left open to the elements.

I'm gonna say this,  I did a lot of work on the KONA, knowing I had a certain budge to spend on it,  and wanted it on the water or the wife was gonna kick my arse if it wasn't read by the time the season started,  I fixed it like it was,  replaced the floor,  like it was,  fixed the seats like they were,  put everything back like it was,  get where I'm going with this ?    :grin:

Ya, mine has a bow tank as well, 24 gallon I believe, mounted the same as what your describing. To be honest, I have been running it for several seasons now & I can count on one hand how many times I needed to refuel during a weekend outing. Granted, everybody uses their boat differently & fuel consumption can wildly differ.... but for a mild lake cruiser I'd think the extra capacity wouldn't be an issue. If the original tank was messed up I guess I could see trying to utilize it.

People told me the same thing, to get rid of the bow tank & put saddle tanks. Get the weight to the back, improve the performance, yadda yadda yadda... While that technically may be true, I still ain't the last one to the sand bar if ya know what I mean. :cheesy: Just depends on how you think you'll be using the boat I suppose.

Dman and Kona Yes I understand easiest way it to put it back the way it was.  I have it here so was just tossing it around. The original tank is a steel tank and although solid has enough surface rust that I scuffed, primed and painted it.  I just don't know if i like having a steel tank in the boat that's 40 years old. and there is no telling what the inside truly looks like after all that time.  This aluminum tank is fairly new looks in good shape is lighter and larger.  argg decisions decisions.

my input, if i come off like a jerk i dont mean to be, just trying to be helpful....

1) you wasted your money at home depot, that ply should at the very least be douglas fir,marine ply is the best... if it is pine you will be doing all of this again in 2 years.

2) there is nothing wrong with an under the floor tank with an access panel, you can rebuild and repair as needed and have the fuel wieght right in front of the motor where it belongs , a neutral place, weight in the front is slower and makes for a better ride, too far back makes for a shitty ride and is faster. you need to box the tank, when you do your seam can be on those ribs and you can glass it in with  layer of cloth, if it needs removing you can easily cut it with a thin cutoff wheel and remove the panel, all of it hides under carpet. if you plan to paint then it will need to be a glassed piece of wood and will have to be screwed in with a pretty visible seam.

3) you can build the floor just above the tank, move the fill and vent to the side and have a deckplate to access the sending unit if needed. like 99.9% of all fishing boats with big tanks are set up.

4) for the strakes use microbaloons and epoxy to make the penut butter texture filler, fill then come back over it with 3 staggered laters of fiberglass cloth getting wider as they come up.

Not necessarily saying not to use it.... just throwin it out there to be kicked around. If you were going to use it, now would be the time to get it in there. Just don't wanna be flying blind & end up with a ill-handling ride cause the tank is in the wrong place.

Use the old tank.  Get a couple handfuls of pea gravel (clean it first) and put it in the gas tank along with about 1/2 gallon of gas.  Vigorously agitate. Rinse.  Repeat several times.  If you can't get it clean that way, it's too far gone. 

My $.02.

screw a steel boat tank, i have an aluminum bow tank too that is in good condition, but i sure as hell wouldnt run a steel tank. wasnt somebody just talking about corrosion? a steel tank is sopposed to be coated, any ethanol will eat it up before you can blink.
