new engine

What is the estimated cost to drop a new engine in an older Master Craft Pro Star. Current engine has a lot of hours on it.
Also new upholstery.

    You want a current e controlled engine? $15K...

    I know a local skier that re-powered his '92 ProStar 190 with new engine and ZeroOff. It was right around $15k

    I would do a compression check on each cylinder first. If they're similar and all are within spec, I would start with a head rebuild, including new valves, seals, springs, and a de-carboning. We did this to a buddy's 350 Chevy, and it feels like it's putting out 300+ horses. AND, it stopped burning oil.

    @AJP0626 - Are you focused on only getting a new engine or amenable to either a crate engine or a rebuild? Ford or Chevy? how many hours is a lot? As you can see from previous comments a wide range on cost depending on which path you take.
  • I rebuilt 205 V in 2020 I bought motor from Michigan for less than $3500. I have a very good mechanic and his charge was about 1500 to pull out old motors and I install. We did the risers and manifolds for another 1200 as I recall in parts from and another $500 in labor. I did it all for a lot less than 15K but it helps for ur mechanic to be loyal and a good friend

    I repowered a zero off 196 2 years ago for less than 5k. New long block, risers and manifolds needed. And labor. Less than 5k. 350, obviously.

    Interior pricing can vary but assuming a 190 or 205, I'd hazard a good average is 2500.

    My buddy had 3,000 hours on his '93 Prostar, and had the engine rebuilt for $2,500. Runs like new again. That's the route I'd go, unless you're looking for ZO of course.

    I have a '91 Supra that I've had since it was my promo boat. Ran it in the salt water on and off for ~20 years with no freshwater cooling. With one top-end rebuild, it lasted for more than 20 years before finally rotting through from the inside out (we flushed it without fail every day). Considered re-build, but we found a '04 ZR6 on craigslist for 5K. At that point, the engine was 9 years old with 50 hours on it (came from a wrecked boat). We had to completely re-do the entire fuel delivery system, so I figure the entire thing cost me about $7k doing it ourselves. Worth every penny. Tons of power, way more fuel efficient, and runs the stargazer system with the z-box as well as a 2014 ZO Mastercraft I ski behind... Definitely recommend casting a wide net for engines out of wrecked boats, even if they're 5 + years old! Of course, if your boat's got a 1" shaft, do be careful with all the extra torque the new engines put out....that's another story.

    Just rebuild your current. Simple, inexpensive, everything goes back as before, runs like new. Done..........

    Anyone rebuild a 240 HP PCM 351 carb FORD? How much did it cost? Anyone drop a new engine in a '94-'96 Ski Nautique? How much did it cost? Anyone know if a 5.3l direct injection could be installed in a '94 Ski Nautique(PCM H5 or equivalent)?

    @Drew_Wright_OBXtoFl its a question of if he wants to repower or modernize. Some of the stars and stripes swapped to a modern Ilmor are sick boats.
  • ReallyGottaSkiReallyGottaSki Posts: 218 Baller
    Define 'lots of hours'...that could help with the decision tree
  • ReallyGottaSkiReallyGottaSki Posts: 218 Baller
    @GaryJanzig yes many have,

    I can add, i've recently taken a carbed 240hp 1100hour 351 to likely 330-340hp with new bearings, chain, alum heads, oil pump, seals, ss exhaust, cam, lifters, pushrods, roller rockers, alum intake and timing cover, crank driven water pump, 140 pound diet for about 3900 soup to nuts. couple hundred on tools i didn't have but choose to buy vs rent or borrow. Some parts i had already accumulated but that number includes typical retail for those items. it pulls hard everywhere, holds ski speed like a rock, and quite efficiently

    I've acquired a low mileage all aluminum LM4 5.3 from a trailblazer for a future towboat project, for $500. Cam and springs will get it from 290 to 320-330 easy. Found a 4" diameter mercuiser heat exchanger for it for 80 bucks.
    should be good somewhat clean fun.

    @GaryJanzig - rebuild cost will be impacted by how much of the work you are willing to do. Doing all the assembly yourself saves a lot and if you take the parts to a machine shop for refurbishing you should end up fairly cheap, hard to give a number until you know what is required. Correct craft fan site has several owners that have done the Ford rebuild thing and can help with parts / costs. New DI install will cost some coin, getting all the electronics and software may be the biggest challenge. Motor mounts and bellhousings may not be the most significant impediment to a mill swap.

    I am at 2100 hours and the number still looked good on the last compression check. Just looking to see what my options are since a new boat is out of reach.
  • DWDW Posts: 2,296 Mega Baller
    @Jody_Seal - the problem with the blue block is obvious, distributor hole is at the wrong end :D

    @GaryJanzig , I think your best Option is to just keep on skiing !
    If it isn't broke don't fix it.

    @Stevie Boy I plan to. I am just planning ahead because a rebuild/replacement will happen eventually. I have been told most engines will need one at 3000 hours.
  • Alberto SoaresAlberto Soares Posts: 333 Solid Baller
    They run lot more than 3000 if well treated

    @GaryJanzig - a simple rebuild of your engine is unquestionably the easiest and least expensive way to go, and your boat will run like new. I did the removal and reinstall action of mine and it was not difficult. My rebuild of the 5.7 GM long block and refresh of the heads was only about $1,500. NAPA machine shop picked it up at my house, did all the work and delivered back to my garage. Having never done a marine removal and install I was nervous but just took a ton of pictures of everything along the way and labeled EVERYTHING to know exactly how things connected and went back together. Unless you’d be unhappy with your boats performance if it were brand new - IMO this is the way to go. Use the time now to scout and screen machine shops to find one you’ll trust and has great references. That’s the hardest part. It’s great having a totally fresh engine again!

    Distributor is on the correct end, just needs to be at an angle
  • GaryJanzigGaryJanzig Posts: 93 Baller
    @Stevie Boy If you find yourself in Western PA between May-October look me up. I will give you a pull.
  • DWDW Posts: 2,296 Mega Baller
    If you do a rebuilt you will also help a local small business if you take your stuff to a local machine shop. The R&R on a marine DD ski boat engine is very easy. In addition, you can find used engine stands and cherry pickers dirt cheap, which is what you need to remove and hold the engine during tear down and assembly. If not you can probably rent.

    @Jody_Seal That might not fit in the existing engine bay but it would have an awesome hole shot.

    @kurtis500 Haven't seen a whole lot of Mopars in ski boats!

    @dbski yeah, theyre all aftermarket builds. The GM blocks have always been great crate motors. Mercruiser makes some darn nice motors and that twin turbo motor is actually a good price. Except you cant put those turbos under an engine housing without cooling jackets and etc.....bummer... Would be nice tho.
