1999 Post 50 MTU 8v183 New to Forum - Few questions.

I know the boat and maintain the Blue hulled 62' Sunseeker predator a few slips past it. I've never been on it, but seems like they did a lot of work to it over the past year or two. It was a good looking boat.

Not sure where your coolant leak is coming from without seeing it. You're going to have to see where it's leaking from. Could be something simple, could be something expensive. I've only run 1 set of 8v183's in my life, we put I think it was 450 hours on them in a year. They had 350 hours when I first met them about 5 years ago, and ran into some EXPENSIVE things to fix with them....one was an exhaust gasket, access was poor, removal of everything was complicated and expensive to fix. I've run lots of 12v183's which is the same motor, just 4 more cylinders. They ran smooth and quiet, but were a little smoky/sooty fuel burn was around 60 gph at 2000 rpms.

If you have the ZF tranny, remove the scraper completely and clean it, if it's equipped with the scraper, and re-install. If it has a tranny filter, replace that, and replace the oil in it. That is where I'd start.

Seth - I have a 2000 '50 and was able to order new door latch parts through Aluminum 2000. They made my salon door for my model year. If you look them up on the website you will find them. The company appears to have been purchased by Pompanette but they still carried components for my door.

I'm looking to buy a 2000 50' post with the same power, if you just bought yours I'm sure you saw it on yachtworld in N Palm Beach. What is your cruise speed and fuel burn? Any comments to the ride (wet or pounding)....I've seen some bad reviews about the 43' in a following sea but that is obviously a different boat. Any info would be helpful. Thanks.

8v183's burn 60 gph at 1950 for the pair..... 65 gph at 2000. I've only run a 50' Post with 820 mans (would be preferable to me). It cruised at 26.5 knots at 1950 rpms and 60 gph..... Boat rode good, very stable running and very stable on the troll, a little on the wet side.....

I’m looking at a 50 post with MTU 8v183 with 3000 hrs and it probably needs an updated service and wondered if this do it yourself possible and what it would entail. Also am looking to cruise at 24kts here in Florida waters at good economy with this boat at .5 mpg. any thoughts on this? Thanks

No, updated service is pulling the injectors/nozzles and injector pump and having them checked/rebuilt. It also includes re-adjusting valves, and doing all the coolers. Have a professional do that.

The set I ran, I cruised at 2000 rpms, which is where they seemed to love to run. Burned 55 gph at that speed. So your figures should be entirely possible.

I’m also looking at another post 50 with v10 mans with 2000 hrs and 2000hrs service completed. There is some confusion over the HP level wether it’s 820 or 1050. They are getting back to me with copies of invoices for the work that will clear this up. Anyway , any thoughts on this boat/engine configuration vs the other 50 post with 3000hr MTU s at8 cylinders and a bit shorter.

I have a customer with a 2001 50' Post with 10 cylinder 820's. The motors have 6,000 original hours on them. He just had the heads redone because they couldn't pull the injectors out of them in place. Motors have never been rebuilt and still run very good. Boat cruises at 27 knots at 1950 rpms. The ideal combination IMO is the 50' with the 820 Man's. He burns 55 gph at that speed. I don't think they built any 50's with 1050 HP mans.

I have a 2000 '50 Post with the 820 MAN's. Great running boat. I'm in the great lakes and my boat cruises about 27knts at 1850 and burn 55gal/hr. Max speed at 2350 is 34 knts. I have a 13ft AB with a 60HP Yamaha on the bow. I see very little change in performance with it on or off the bow. To Capt J's point above regarding 1050's - I did look at a 1999 '50 about 8 years ago while hunting for mine with 1050's. They claim only a few were built with those engines.

Seth can you contact me about your luck with those engines. Dan 8608237570

I think it was one with 1100 Mans is that a 1050? That's when the double air vents on each side first appeared.

Dan you may get some very interesting calls with that number out there. Send a private message?

I found the old add. It must have been a 1998 that I looked at...

Have any of you handled the Gelcoat issue on your Post . I’m looking at a 2000 with this problem and wondered what I’m getting into here. The hull has already been painted 9 yrs ago and looks great. The cockpit also was done. Any thoughts?
