i just bought a 78' tx19 youngblood 3 weeks ago and i blew the motor yesterday right through the top of the oil pan and bottom of the block. i was told the motor only had nine hours on it. i was wanting some information on what parts i need or would it be better to just buy new motor. the block number is D1ve 460 with supposedly over 600hp. the boat was running fine when broke. i was running at 4k on the tach when she let go. would greatly appreciate some wisdom on this matter. maybe a ballpark figure on price to fix at speed shop, or the parts to buy. thank you.

That exact same thing happened to me to when I bought my boat (melted piston). In fact, most everyone goes through that when buying a new jet boat. I call it the jet boat tax. We build 460's and 8 times out of 10 the customer "just bought the boat" and--boom--it grenaded. 454, 460, 455, it doesn't really matter....

If you truly have a 600 hp 460, then I assume you have some really nice parts in it. If that's the case then you are probably better off tearing the engine down, assessing damage, and rebuilding what you have. Hopefully you will only need to rebuild the shortblock onto which you could install your top end, for example.
Cost? $1500-$7500 depending on what you really have for a shortblock, the cost of replacing the parts and/or which direction you decide to go in order to get back in the water. Of course it might not really have 600 hp and a simple engine rebuild will have you back in the water. Whatever you do, DO NOT purchase a rebuilt engine from an auto parts store; the money you think you are saving will ultimately be further invested into the engine shortly thereafter.....conitinue to do you your homework and rebuild the engine right the first time.

thanks lakesonly. it sounds like to me i need to find a block and start in that direction. will any D1ve block work before machining?

If you have a D1VE block now then the chances are that any D1VE block will serve as a replacement. In fact, any C8VE, C9VE, D0VE, or D1VE block ought to serve as a replacement. Whether or not a D9TE block can serve as a replacement depends on the actual rotating assy in your engine, but if it's a 460 OEM internal balance crank in a D1VE block the D9TE block will not likely be a suitor.
You really need to first tear down the engine and see what you're working with....

thanks for the info. i'm gonna call the local speed shop tommorrow to see if they can tear it down and see how bad it is.
-

-

heard nothing but good stuff about Duane
-
when i met him today he seemed pretty dam sharp. i'm glad to hear other people had the same opinion. it feels good to find a guy i can trust with my boat rather than some hack at a speed shop!
-
he pretty much knew right of the bat one of the reasons of the mechanical failure was the oil pan and sump was his first guess. i knew better when i bought the boat but the guy said he never had a problem with it.
-
Duane's a great guy, and he knows his way around a jet boat. You've made a good choice. :thumbup:
-
thanks luckie stiff. i just hope my pocket book can afford him!

X2 thats the hard part :banghead: but in the long run its the only way
-
X3, you can't NOT afford him. Cost you quite a bit more to have some hack rebuild your motor ever winter........ :sly:

thanks for the info luckie stiff! I talked to the guy sounds like a good deal. i just need to see if duane will do that as far as putting my top half together with this guys bottom half.
-
Happy to help. Sounds like a good deal for the money. I'm sure Duane will be ok with it. Good luck!
-
what does the 1/2 fill on the block do? is that a good thing or bad thing? the one sleeve kind of scares me to.
-
The block is half filled with water passage filler, I'm not sure how that will affect it's use in a boat. The sleeve doesn't scare me any.
-
is anybody familiar with a 1/2 fill block on a boat?
-
i got some good news today. duane tore down my motor and said that my block could be saved! thats a big money saver. hell yeah!
