Why do people do that (Missrepresent)? Cars in "mint condition" that are rust buckets but priced mint. Bikes with plastic missing (Picture shows the good side). Worse still when the item is out of town.

When we were in the market for a set of jetskis about 10-12 years ago I went and looked at a few that were so insanely misrepresented it was disgusting. One particularly memorable one we drove an hour to see had photos that had to be taken in the first few months of ownership (on a 8-10 year old machine) only for us to arrive and find the ski literally sitting on its belly in the gravel driveway, half on its side, the seat sun bleached and torn, the plastic all sun faded, & the gunnels full of ice.

I was infuriated. I didn’t even ring the doorbell. We just left. Dude messaged me back an hour later via Kijiji asking why I no-showed.
 
Our CFO at work bought a Kawasaki PWC about two months ago , beautiful black/green machine . Had significant whack out of the gelcoat below the waterline, not glass just big gelcoat chuck , size of two toonies. Seller said he bumped a dock. I get under it to make repairs and find 5 more big chips all they way to the stern , my guess buddy skipped it over a rock shoal . Nice.
Same deal with a Polaris PWC he bought a few years ago, seller says it's 100% , I go and tow it home for him from London, we launch in Oakville and cant get it over 20kph. Start disassembly and its got a 12" tree branch jammed into the water intake for the jet . Called seller who was "shocked" . Trust nobody when it comes to anything more complicated than a canoe .
 
Reviving this one.

Long story short, the Doral is in the running again. After looking at the smaller options I think the realities of downsizing didn't look appealing in a lot of ways.

No room to extract injectors without major surgery. Tens of thousands just to get access. I can't remember if they split the hull or disassembled and rebuilt the cabin

This is one of the main attractions that led me and my BIL to really fall in love with the Doral - the engine bay is massive and the access hatch is a huge portion of the cabin area, hydraulically operated to open and close. Ladder access. Lots of room to sit down there and contemplate life while fixing the next things that needs fixing lol.

(Actually, given a 2017 repower with modern engines, hopefully that last bit is minimized lol)

Even more room with the original 7.4s gone in exchange for the 5.7mags. Down only 10hp per side, but down ~7GPH @3500RPM, so measurable fuel savings, and all modern electronic engines. Technology came a long way in those ~15 years.

While down in there vetting the engines I could actually picture us working in there and not cursing and swearing endlessly.

You'll have even more space once I get that Kholer gen set out of your way......

That’s a feature they want. No more lugging around a portable anymore for weekends away. Even more important since the cooktop is electric. Plus….coffee maker. Essential kit. lol.

I'd dump the Kohler - with a modern repower I'd use a main engine as the gennie -- it will use about the same amount of fuel as a 16hp gas Kohler. I did that with my last cruiser - sold the Gennie, installed 250A marine alternators (3kw each) , external regulators, and a pure sine wave inverter with 2x 15K circuits. You can keep and use the same house batteries.

Gennies are a PIA to maintain, they take up space, and add weight. Eliminating their 600lbs of machine, plumbing and controls reduces maintenance cost and increases fuel efficiency between 3 and 6%.
 
So when you want to run the AC(s) (the 360se has two) for a few hours while tied up somewhere, or overnight, you run one of both of your mains?

A typical 2-3 nighter trip for us would be up to Kirkfield (maybe even Orillia with this one now, but the trip across Simcoe isnt always fun) with stops in Bobcaygeon, Fenelon Falls, Rosedale, usually some time at the sandbar on Balsam…..etc. Any one of those areas may require power for whatever, and overnight AC potentially if it’s miserable out.

That genny is only a few hundred pounds BTW, I think the manual specs it at 205 IIRC. Maintenance, meh, oil changes and zincs.
 
Keep the gen set imo. If the unlikely event the kholer packs it in , seven grand and your back in business with three wires and four bolts . Pop in a yanmar or Olin diesel gen and your ten g’s and running forever. Those main engines are design to run under load , not an alternator load , they will just eat themselves at idle for a twenty five g replace . Dude that specd the Kholer didn’t drop it in to jack the price , it’s a good idea .

Kohler 8e marine genie (typical for that boat) is 443 dry. Add another 100lbs for controls & transfer switch, motor mounts, plumbing, exhaust, and fluids. 200lbs would be a modern air cooled RV genie.

Maint is a bit more than that. Winterizing, filters, screens, and another set of thruhuls to keep an eye on.

To each his own, but for this mariner a 20 year old marine genies vs power off 2 modern mains is a no brainer.
 
Ah yes, I was looking at kg vs lbs on weight.

But removing 500# of generator (and let let’s be real, not everything is coming out, some of the controls are integrated with the boat) only to install 100# or whatever of additional hardware in the form of a honking inverter and oversized alternators etc etc doesn’t constitute any meaningful weight savings in the grand scheme of a boat that weighs this much to begin with.

And then you’re still idling 1 or both of your mains to run loads for long periods. Personally, I agree with others that replacing/rebuilding a genset is a lot cheaper than mains.

If the mains have logs would the hours create a problem later? Like the contractor service vans that idle all day in winter so the workers have a heated shelter for breaks. One MPG for the day, Low Kms but the engine never rests.

Doesn’t really matter on a privately owned item, you operate it as you see fit. Doesn’t mean it’s not going to add a lot of wear and tear to a set of very expensive engines vs a drastically less expensive genset.

I’d also be curious what the duty cycle is on those big alternators. They’re rarely 100%, and if you’re trying to make 120v@50 amps that’s a 550 amps on the DC side, so a set of 250a alternators is not only not even keeping up, but are running at 100%.

Even a more realistic load, say 25a AC to run a single AC and some other small things, 270a on the DC, so you need to be running *both* mains and those alternators would be still working hard. I can’t see the longevity equaling that of a genny personally.

Is the AC water cooled heat exchanger or redneck hole in the side of the boat?

How is it possible for it to be so horribly inefficient then with a water-cooled exchanger I would expect it to be well under 10 amps

16,000BTU air conditioner. And don’t forget the air-conditioning AC voltage load, Not DC, so a marine 16K BTU AC draws around 14 amps from what I can see, and that correlates to around 150A DC while just running. Start load can be many times that. There’s also inverter efficiency losses.

Now add in the stove being used for a meal at the same time, microwave perhaps as well, coffee maker, next thing you know you’re running both engines.

Yes you could probably get away with one main for an overnight I guess when there are no other loads except the AC, but you would still be running that 200a alternator at potentially 75% duty cycle (with regular spikes to 100%) which it may not like much.

Our van has a 6k DC air conditioning uses 50a at full tilt water cooling should double the efficiency. 300 amp lithium battery bank can run it for 3 to 4 days normally
