might be getting a 75 tahiti 19' good price?

friend of mine is getting rid of his boat. daughter is going through medical problems so he lacks the time/money to ever take the thing out.

I dont remember when he got it, but in 2009 he started putting money into it and it is running a fully rebuilt olds 455/ berkley 12jc pump. I dont know all the specific parts in the motor right now but the few things I do remember that he has told me before is that it has high tension dual valve springs in the head and a snyder racing cam, and a pertronix dist.


trailer has a new axle and 2 spare tires. boat has a new wiring harness, new stereo system. autometer pro comp gauges, and Im sure theres more money into it as well.

I dont remember the RPM but he says it does 62 and the jet pump is just all still stock parts, no stuffers/inducers/loaders/whatever. no idea on what impeller.

I live in AZ and the boat is over in CA, this guy was my best friend throughout school from kindergarten til I moved away in 7th grade but I still go out there now and then so I trust everything he tells me about the boat. looking on craigslist here jet boats range from 3500-11k and I really dont see why some are so much more than the other, obviously they sound a little better but not almost 4x better so I dont know which ones i should compare to but he said he will give it to me for 3k and I am pretty sure I am going to do it because he is even going to let me take it with not much down and make payments, that PLUS I know who has owned it for the last 5+ years and how it has been maintained. does 3k sound like a good deal? he said he might get me a running video of it today and maybe some pics so I can post them so you can see what I am talking about.


*yes, this will be my first boat ever, and while you might want to say its not the boat to start out with, I am mechanically inclined and do all my own repairs on my own vehicles from the plugs all the way to transmission swaps and engine rebuilds so I should be able to fix anything that goes wrong as well as decently troubleshoot any problems that should (will) arrise.

couple more, and now I know that its not snyder racing, its schneider racing. also got a 750cfm edelbrock carb.

also, it does 62mph @ 4900rpm and he always runs valvoline vr1 in it. it has a circle track pan instead of a full marine pan so it only holds around 8+ quarts of oil instead of closer to 15. but he said you can run it at 3800 all day and it never gets hot, but wide open for too long and it will start to get hot. was going to put an accumulator and cooler on it but just hasnt done it yet.

Looks like the perfect little starter boat. If the motor and pump are in good condition then 3k is a good deal. Dont be surprised or discouraged if youhave to sink more money into it though. These thinggs are money pits! Have fun with it.

You dont want to run that thing wide open for any long period of time. Olds motors are notorious for having oiling issues and you could possibly ruin the motor. Just cruise it and have fun.

I am up in prescott valley for a while longer, trying to get a job up in WA state right now so will be moving back in a couple months if I get it, even if I dont I will be back up there by the end of the year because the ol ladys family is ALL up there and I got her to follow me down here but now after almost 5 years she wants to be near the family again...

anyways I think lake pleasant will be the closest lake for me to take the boat out around here.

also, he has warned me a couple times that even though hes gone through it things happen and that B.O.A.T. does stand for "bust out another thousand".

I know the motor is good, I am not sure if the pump is recently rebuilt or not. but he told me the motor fires up before the starters had a chance to work for more than a half a second, it idles nice(well it doesnt idle real smooth since its a cammed big block...) but it will purr like i kitten at whatever rpm you want to run it at and will go from idle to screaming to idle without ever missing a beat. his family owns a few muffler shops so they have been around cars/race cars forever, and they have all at one point in time had their firebirds, roadrunners, etc... and all of them built so they all know what they are doing. also was just reading about olds oiling issues and some are running the cam bearing oil restrictors, some run the restrictor push rods, some dont believe in any of it... so im not yet sure if there is anything to do preventative-wise other than a big oil pan and a high volume pump(not sure if this boat has one already or not).

also any guesses on how heavy this thing is on the trailer? he has a little standard cab sonoma with a 4 cylinder that he tows it with sometimes instead of their tahoe, but has a hard time getting traction to get it out of the water. I know a 92 extended cab V6 nissan hardbody weighs more, just wondering if Ill end up having the same problems because I also am only 2wd. I do have a js550 I could throw in the bed to get a little more grip in the rear... and it is something youd normally take to a lake anyways so I guess if I have to bring that too its no big deal :thumb:

prescott valley is a nice area...ive got a buddy thats from chino...i would think that rosevelt and apache are closer than plesent but i may be wrong...i dont think you'll have any problems towing with your nissan...if the ramp is really steep and slippery you may spin the tires going up but i pull mine out with a 4.0 6 cyl cherokee sport and never put it in 4wd to get out...im moving back to az in a few months if your still there i may see ya on the water...taker easy

My first boat was a 1975 Tahiti Tiger, same boat. That hull was Tahiti's low end entry level boat, brand new they were around $4200.00 depending on the power package, Olds, Ford or Chevy....Olds was the least expensive. For a lake boat, they are just fine and with a little care/maintainance along with taking it easy on the throttle, it'll last quite awhile. What it's not built for is too much speed, 80 would be pushing it a bit without some work on the bottom. The hull itself is what's known as a 1/4 stringer which is the wood that the engine is mounted to. Being that it's only a 1/4 stringer, it has a floor that is built on a frame that is attached to the hull. If there hasn't been any work done to the floor, there is a good chance that there is water tapped beneath it. If it hasn't already been done, it's a good idea to drill a hole in the bulkhead that goes from stringer to stringer in front of the engine so the water can drain out. After it's out, you can seal the wood and then use a removable plug so it can be drained. If water has been trapped under the floor for any length of time, the floor could be rotting from the bottom up along with having water soaked flotation.
The other area of possible concern are the stringers themselves where the motor mounts are bolted to it. On many of them, the holes were drilled but no sealant was used to protect the wood so it's a place for rot to start.
More than likely it will have about 3/16" of hook on the bottom. If you put a straight edge on the bottom lengthwise from the transom forward, you will see a gap between the straight edge and the bottom of the boat. It's not such a bad thing for a 60-65 mph boat as it will actually make it ride better.
Your friend is correct about the engine and the rpm, mine was the same eay. It would run all day long without any issues at all up to about 4000 rpm but after that, I had to really keep an eye on the oil pressure gauge. With the oiling issues in the Olds and hot oil from running hard, it would start to drop oil pressure, nothing serious but I never kept my foot in it to find out how low the pressure would get. After using it for 11 yrs and not doing anything to the engine, it was still running strong when I sold it.
As far as weight goes, I think it's somewhere around 3000lbs with trailer, gear and a full tank of gas. I pu;;ed mine for a few years with a '72 Jeep CJ5 and it worked great except when there was a pretty good crosswind. There were a few times when a gust of wind would come up and push me a few feet in one direction or another. The other little issue was with the 4 wheel drum brakes and stopping but that shouldn't be an issue with the vehicle you're thinking of using.

All in all, it's a good little boat and not a bad price for $3K. There are times I wish I would have kept mine, it got really good gas mileage for a jet and it just kept on going like the energizer bunny.

If you get it, just have fun with it. leave it relatively the way it is and it'll give you years of memory making service.

how'd that aluminum plate work out? got any pictures of what you did?
it worked out great. thank you VERY much! i ended up pulling out the pump, grinded out the cracked sections of the "box"... glassed it all up front and back. put the pump back in and mounted it with the plate. it was nice because i could actually get the bolts tight without it just shushing the fiberglass.



i do need to ask you if theres anything i can do to my pump when i go full turn. it likes to squirt back at me from the sides... any suggestions?

alright, Ive never been over 40 on a boat before so 62 should satisfy me for a little while. my only plans performance wise is just parts for the pump like bowl stuffers, or loaders, etc... to try and get a few more mph out of it later on. I really like the looks of dry stacks vs the wet headers also, but being able to leave stuff like a cooler back there without melting it sounds good too so I dont know if Id ever swap them out.


reliability wise I want to throw an oil cooler on it right away, and maybe some day pull off the heads and enlarge the oil drain holes and have been reading about a few other tricks people mention on different sites.

about towing it, the truck is rear drum, but the front brakes seem are much better than the i4 trucks. when I did the front brakes the other day, I got the pads listed for the 2wd V6 online and they were wrong, so I went to the local parts store to get the right ones and their 2wd V6 pads were the same (wrong) ones I already had. so I had them give me the 4wd ones that have about twice the contact area and they ended up being the right ones, and my calipers are the same dual piston calipers from the 4x4's as well. I think this is all factory equipment and just the catalogs have their info wrong.

as far as all the water getting into the boat issues, I will have a look at all that when I get the boat. as of now I am picking it up around the end of april when I get home from a job back east. I got a video of it yesterday and as soon as that key is turned it is running, and it sounds healthy.


do you think that with just pump work/adjustments the boat could break 70 if it can pull 62 now with all stock parts(no idea on what impeller though)

and stokerdude, I think I saw in the thread about the 77 sleekcraft in this section that you were talking about getting one and they linked that 26' ambassador on cl, that thing was tempting me but I know I wouldnt be able to get it and a motor/drive for less than this boat, and I dont think Im pulling no 26 footer with a nissan hardbody... someday I would love to have a hull like that though. but I will always have to have a smaller faster boat as well...

Good boat to start with. I'd run it before buying a bunch of stuff for it. See what you need and how it handles. Go have fun with it first. You'll be spending enough money on it to keep it going let alone adding anything to it!!! LOL
If you do end up in Washington, there's a great group of guys there as well that are more than willing to give advice.

You need to be careful if and when you start adding items to the pump. There is a chance that you could over load the pump and you would lose mph due to the engine not being able to overcome that load. Personally, I'd freshen up the pump or at least check it out to make sure there aren't any major issues, go with a better loader, a diverter and maybe a droop but that's about it. Those things would happen after getting out and using it for awhile so you can get an idea on what it's doing or not doing.

I'm glad it worked out for you and it looks really good too! There should be a threaded hole down low on either side of the nozzle that you can put a couple of bolts or studs in to stop the nozzle from turning all the way. It should only lose about a 1/4" of movement to stop the back seat showers.

washington really isnt an if, more of a when. Id be perfectly fine staying around this area but I guess you gotta keep the wife happy (soon-to-be anyways). I think we are going to end up either in marysville or bothell/mill creek area. never was out in marysville much so I dont know what lake/s are close to that area.

also i just checked the map, I have no clue where lake apache is, but lake roosevelet is definitely further than pleasant. pleasant is north west of phoenix, roosevelt is east of phoenix and Im pretty much dead north of phoenix. 83mi to pleasant and 144 to roosevelt. few local lakes but they are all too small.

what is a good oil cooler that doesnt cost a ton?
