  • I curious what your final total costs will be when you are done, and, if you think it was all worth it. Would another used/newer boat have been a better idea? Good luck guys. I hope it all works out. And, I hope you do give an honest final cost when you're done.

  • Buy a good 903 and put back in there. Huge very expensive mistake going to gas. No torque, horrible economy and performance. You'll be fighting the throttles constantly in any kind a sea.

  • You didn’t do very good research, those Cummins VTA 903 marine engines are available on eBay 500hp and with warranty for $4995. Each. Problem with putting gas in your boat will automatically loose half it’s value when you decide to dump it.

  • Those pieces of rubber are the water pump, you should have replaced both impellers when you bought the boat, there is certain things that don’t last forever on a old boat,

  • I’m guessing that the turbo blew an oil seal. If it was a crank seal I don’t see you dumping 11 gallons of oil in the bilge in a short time without evidence on the outside of the block. If the turbo seal went you could pump it out the exhaust

  • The fact it was re-propped for higher revs says the original diesel engines might not be the ideal engines for the boat. So why not try the LS option. Economy is irrelevant when talking fast cruiser boats that are just going to be used for fun. If you don't know the question. LS is the answer.

  • What muppets. Looking for oil leaks 🤣🤣 if you checked the oil level before you started it that day you would have known your engine was using oil. I served my time on them V8 cummins and Perkins. They take 38 liters of engine oil. A little oil stain on the bottom of the raw water pump really is not what your problem is. I dont feel sorry for you . How u have 1.45 milion subs is worrying. Learn to check your oil its a 30 year old engine 🤣🤣

  • nobody ever goes from turbo diesel to gas. gas never lasts as long with 1000 hours being max time. gas will be 4 to 5 times the fuel costs over turbo diesel. a good change out would be turbo 6bt or turbo 3208. also the resale value of the boat will take a big hit with gas. gas is also very dangerous on a boat.

  • I'd put those 7 thousand pound diesel engs. on a tug and haul them out past the bar and drop them to make a artificial reef. Then I'd build a outboard bracket and bolt on 3 450 h.p. outboards and be done with it. You're putting way too much work into the boat. Easy outboards! Easy maintenance! Easy replacement! And...1/4 of the weight, and better performance.

  • Did anyone ever check the oil level or better yet change it? Oil and filter would be minimum engine maintenance, possibly a compression test prior to purchase would have been a good idea as well. If the toasted water pump cooked the sleeve seals it was over before you turned the motor over. 5 gallons is a monster amount of oil. If it went into the hull it would look like a tanker oil spill, where did it all go?

    • That's a great question. Do we even know for a fact that there WAS oil in this engine before the trip started? (They have these things called dip-sticks, that, while admittedly not as high tech as remote reading oil pressure gauges, are exceedingly reliable - and, if you're a hopelessly behind the times old geezer, should be checked before every trip.) If it went into the drip pan or bilge, that would be obvious. If it got burned, that should have left massive exhaust smoke. If it went overboard un-burned, that should have left an obvious slick. Something doesn't smell right about this.

  • If I had to guess... impeller chunks in the cooling system caused overheating which damaged the internals of the engine, causing oil issues and finally critical failure. Guess this is why all the marine engine video channels have impellers as one of the first maintenance items they display.

  • Owning a marine repair shop I am curious of how long the "performance" engines will last. Unlike cars where racing and such is a very brief load on the engine, pushing a big boat through water may be using the engine at peak hp/tq output for literally hours on end, WOT with enough drag to keep it off the limiter 24/7 for the rest of its life. I'm not saying it won't work, I'm just curious how well it will work for an extended period. Also, yes the previous owner either swapped the impeller himself and didn't clean the shredded chunks out or has a fully incompetent mechanic. From there, reduced water flow overheated the engine, something gets hot and let water through, I see it all the time, any time we find a damaged impeller we pull the entire cooling system apart until we find all the remnants, and flush all the lines of the powderized stuff.

  • Long story short, if you plan on keeping that yacht, I would take the time and rebuild those Cummins. Once you swamp them out and go alternate you'll lose in the long run, the resell value will plummet, the market for a alternately powered yacht will be almost non-existent. Unlike cars, yachts/boats in general are waiting games, basically money pits. When you jump into the class you're in, they're mostly maid for people who have a lot of money and like to throw it at stuff to fix it. In fact that's in general almost all boats/yachts. Once you rebuild those Cummins, with proper preventative maintenance they'll last for quiet some time especially if you're proactive. Either way good luck i do like watching this.

  • My friend, I just restored a 1992 Riva 50 Superamerica HP. These boats are top of the line in every way, superior quality. No way would I put gas engines in a Riva 43 Tropicana unless I was willing to give it away for a fraction of the value. My Riva 50 has twin MAN 510's, and they are also 30 years old, but they run like new because they were maintained properly and only have 500 hours on them. They are expensive engines to maintain, but they make the boat. Riva uses diesels for a reason. Why not just rebuild your Cummins engines? My good friend, Riva Guru, is a Riva dealer/restorer in Ft. Lauderdale: rivaguru.com/contact/ I am sure he will tell you that what you are planning to do is a really bad idea. I believe top speed on the Tropicana is 35 knots.

  • Do the old Riva the justice she deserves. Get the other engine out, make the bilge mint. And do the rebuild with help from knowledgeable folks on here. If they wernt good and bulletproof the parts would be discontinued. I mean 3 weeksfor parts against bespoke untested parts??? Mint engine bay with 2 rebuilt originals is the only way to retain any value. Sorry mate your taking the wrong path.

  • Boats don't need Horsepower. They need Torque. That is why the original spec for the boat was diesel. Boats need longevity. That's why the original spec was for diesel. Efficiency matters in a boat. That's why the original spec was for diesel. You are making a HUGE mistake! You are putting serious time and money into this boat, and that's commendable. But, you are doing WAY too much GUESSING on what to do! Get some knowledge before you make these decisions, and you'll be happier in the long run. You say one reason to replace those big engines is because they are too big. Too big. Oh, poor me... my engines are too big in my 20k pound yacht. Does this make sense to anyone? Talking about fire hazard... another major reason you use diesel in a large boat is explosion. Gasoline explodes, diesel does not, and you are going to carry hundreds of gallons of gasoline. Besides, don't you have a diesel generator? Now you have to add another fuel tank. You could rebuild those diesels for far less than replacing them. And, what you save in fuel cost with diesels in the first year over the gassers would cover the rebuild cost. I'm sorry, man... but you are doing all this work to "restore" the boat, but the engine decision is ruining this boat.

The best thing about LS engines is they're cheap, everything else you get what you pay for, I don't think he's going to want to have to do all the continuous maintenance LS engines require on a boat that takes so much time and expense to pull engines out of. But hey, at least he's having them built aftermarket, that should help him a lot.
