quistion about a hull

[jet guy]

I have a 69 tahiti is this a good hull I like to go skiing and going fast but I dont race (much) so is the hull a good one:confused: I like the why it looks but is it worth spending money on

[JR131]

it really depends on which model that you bought post some picts of the side,the front, the front, then check the bottom down the keel to see if it has a suction cup on it "not good" then your questions can be better answered

32866 these are the pics i have do they help? i can get more if needed i think the model is a tiger

[JR131]

keep it as a skii boat dont spend alot of money on it (because you will not recover the moneys spent when you go to sell it)keep it for pretty much pleasure only, if you try to put any kind of horse power in this particular style hull the boat "could and would" become a little dangerous due to the deep forfoot bow
have fun

what is unsafe about this and what kind of trouble will it give and will a 454 or 502 be a waste of money it has an olds now i plan on keeping the boat for awhile

well if it comes with an olds use it till it blows up. then see if it handles like you want. just my .02. just dont bring it up over 4500 rpm's cause that olds will blow quicker than shizzle...:D

[JR131]

oh by all means no that wil not a problem my bad most people when they talk about adding power to the motor they want to add a big camshaft,dual carbs more compression so on and so on you will be fine

Im thinkin a 454 with 2 4s on a tunnal ram but would like to have the hull xrayed for cracks before the chevy is this something anyone can do or should I take it to someone speciel

you might want to get your local marine shop to check your boat for you. and is the tunnel ram gonna be for looks? or for speed?

[jet guy]

I would like to go fast sometimes so I guess both but also to look cool

[jet guy]

I was hoping to 60 or 70 is this to much to ask of this hull and will it saftly do it

[old rigger]

Anytime you push this bottom 70 and above you're going to have your hands full when you let off the gas. Like jr131 was telling you, the deep entry on the bottom of this hull will want to bow steer when it re-enters the water at speed. The boat will make a violent turn, maybe, to the right or the left, or spin out out all together.
But as a family cruiser running up to 65 or 70, it'll be great.
This boat below, the shorter 16' Tahiti bottom, yours is a foot and a half longer but the same, was at the time the worlds fastest jet, but no one would race him because at the end of the 1/4 mile the boat would change lanes at will. We've come a long way in the last 40 years and the Tahiti with that bottom can be made to handle a little better, but what's the point? It is what it is an should be treated as such. You want to go faster, there's a world of better hulls out there to do it in. :)

Looks like a great boat to me...remember that fast is all relative here! I would see how it drives now and gradually increase things, especially if it is basically just for your driving pleasure. My 16ft Cobrajet does 70mph (GPS'd) and I have no problems whatsoever with hooking or such. I am building a fairly stout 468 (approx 540hp) for it now and I am not too worried about having too much power, but I'm also not looking for any more top speed either.
Just depends on what your future plans are...I would say enjoy it!!

[jetboat]

keep it simple!i have two boats avenger and taylor.the avenger is a lake only boat and runs everyday at 53+mph,has a medium built 466 ford,its est.at around 480 hp+_and will probley run mid 70"s.dont belive everyone 80mph!the avarage is problety mid 60"s.enjoy what you have with your hull type.if speed is your thing,go to a tx-19 type hull and spend$$$$$$$$$$$$$$$$$$$$.to go fast.reach your lmit and have fun.

[jet guy]

thanks for the info im still learning about these and like to hear everone 2 cents :)

[n8dawg]

How does the boat handle right now at speed?

[jet guy]

Iv only had it 3 times problem with regestration and the boat has a bad electrical system so Iv hade to do alot of work but I had it out last weekend got the reg. done finlly but it ran great handled great the water was a little choppy but it handled great and had allot of fun I dont have gps yet the old speedo said 40 to 45 mph but dont know how close it is but in the chop and full throttle it was fine and slowing down gave no problem but it was not close to as fast as Id like to go but mainly I would just cruse around ski or pull a tube but sometimes would run flat out :devil:

[ck7684]

I dont run mine when it very choppy at all...it'll put the bow right under some waves, or even my own wake if I slow down then turn around 180*
Anyways, my speedo will only read up to about 60, and there is major lag time before the speedo catches up with my actual speed. I think a GPS is about the only decent way to know for sure...
How long is that boat anyways??

[n8dawg]

If I were you I would go ahead and put the 454 or 502 in, hang onto the olds. That way if your un happy with the attitude of the boat at speed, you can through the olds back in and sell it keeping the chevy for whatever you end up getting next.
I've come to find that there's alot of trial and error with finding the right set up. Just keep pluggin away at it.
Good luck.

[jet guy]

When you see sand, you floor it:D . Remember in a jet, "When in doubt, throttle out"

[jet guy]

how reliable is the old speedo is it even close or not at all in the ball park mine says adout 45 how close is that

Seems like I have read around here somewhere, that the two gauges on a boat that you don't want to trust are the speedometer & the gas gauge.
I have found this to be true with my gas gauge. :D
My speedo is likely to be what came in the boat in '77, but when GPSing my boat, I found it to be surprisingly accurate. It was reading one mph slower than the GPS. But I have also heard the pitot type speedometers are only accurate up to 55 or so...
