Engine life question

[Jetlink]

Ok, got back from the Chicago boat show here today and of course saw/drooled over all the new wake boats out there. My fiance has wanted a V-Drive since about a week after we got the comp. Talking to the dealer today they have a used 2007 v-drive that is her dream boat that she wants...just looked it up and it has 1600 hours on the engine. What's the typical TBO (time before overhaul) on these engines usually out of curiosity?

[ahyshka]

If the engine has had regular maintenance, and you keep up with it Id say run it on condition. 2000-2500? is probably a good safe tbo though. I hope someone else chimes in because I am not entirely sure with these engines.

That's a lot of hours in a short time .Was it used for a ski school? What model and how much do they want for it? I agree with ahyshka 2000 is considered very high . It is possible to go much higher but if it was a hard working ski school boat the engine is probably tired. Have it completely checked by a independent mechanic before you buy.

Ben , quit dangling teaser's w/out the make and model.... I might guess its a Nautique??

7 years ago I had the 351 in my comp rebuilt at 1234 hrs. thinking it had to be getting worn out. But when the Tec. got it apart he was surprised . Very little ring ridge & the bearings were good . Except for the balancing I should have let it alone.

Ben , quit dangling teaser's w/out the make and model.... I might guess its a Nautique??Ding ding, John is the winner... It was a boat that the dealer used as a ski/wake school boat. 2007 Air Nautique team edition fully loaded on a trailer for $39,850...I know, why is this being asked on the supra forum but, I am loyal to the Supra brand as much as I can but if there is a steal to be had, I might take it. This doesn't sound like a steal the more I think about it, as much as I would like to "pull a Daff" and have more than one boat, I think now is the time to pass.

07 was the first year for the new hull it is the only year for that interior . Because of the interior it is less popular than 08 and up. With that many hours it doesn't look like a deal I have seen them with less hours for that price a year ago. If you are going to go with a SANTE I would go with a 08,10,11 and 12 models.

IMO, that is WAAAAAYYY too high. Think of it this way, when you put 1,000 hours on it and need to sell it who are you going to get to buy it for anywhere close to that? I wouldn't buy it for any more than $29k to 32k. But, that is the Nautique and Mastercraft way...charge high, hope someone bites.

[mapleleaf]

And uh, you saw my Conbrio right??? Bought it from a camp....they ride'em hard.....

[Jetlink]

Like I said, thinking of taking a total pass on this one, which is fine with both of us. It blew me away though how many hours were on the engine.

[docdrs]

the one bright thing about this thread is look how many more hours we can put on our motors before we get to that number.... :)

Eng have come a long way in the past 20-30 years.

In the '70 a car with 100k was worn out now days its not uncomon to go three times that.
I know the load and wear on a marine eng is much higher.

My old truck '99 gmc 2500 has 320,000 on it with most of those miles pulling an airstream.
The 75000 I have put on it have mostly been overloaded.

I think we will see marine eng's with 4-5000hours on them still geting the job done.

Price is still real high

[haugy]

That's not a great deal. I would pass on it completely.


And here's some fun about the Supra 351 engine. My comp had 786 hours on it before it was vandalized. I then put the motor in my CJ7 rockcrawler which has put an additional 15,000 miles on it. While 15,000 doesn't sound like much, 90% of that is hard revving rock crawling hell. It still kicks with tons of torque and still amazes people who see it. It's only had plugs and oil changed.

:D

Sorry, but engine's haven't come very far in 20-30 years. They're using the same materials, internal parts, and design. I had a '67 Galaxie with a 289 I sold with 302,000 miles on it and it ran great. My '68 Galaxie had a 302 in it and it had two pistons just along for the ride at under 100,000 miles... That engine was neglected for the 5 years or so prior to when I got it. It was run on 87 octane and as such it detonated at anything more than off idle and dieseled every time it was turned off. This car has been in the family since brand new in '68 and it was my uncle that abused it. I ditched the 302 and built a 460 for it, and now it's slowly getting a body work done as time permits. Anyhow, the 289 wasn't exactly well cared for, but it wasn't outright abused like that 302 was. They call them "the forever engine" for a reason. 351w is basically a tall deck longer stroke 289. It's a 50 year old design and nothing has changed since introduced. Pretty similar deal for the SBC.

Point being, engines now are the same as they were 40-50 years ago. When we look at marine engines we're talking small block Ford, 460, 350 Chev, or 454. These are all 40-50 year old engines, and they put them in brand new boats.

My point is casting processes, metallurgy and machining have come a long way.

The basic design is the same.

The things they are made of are better.
the ability to control the metal chemistry has changed alot.
If you got over 300k on an engine from the '60s you where lucky.

[michael hunter]

Ford small blocks are gone forever most wake boats today use the 5.7L and 6L Chevy engines. They are nothing like the engines used 40 years ago. The problem is not the hours on this boat. The asking price is too high for a boat with two thirds of its life used up.
