    So you used these to replace the interior courtesy lights, correct? I have to imagine they were plenty bright. Coming from my old Ebbtide which designed the lighting to be dim and horrible, I am looking for bright but not 'sunglasses at night' bright.

    Thanks,
    Mik

    They are bright, but not obnoxious. They do light up the cabin. We got them so we could see to unload at night, not for ambiance. They make a 1 and 2 mile version if you are concerned. Or better yet, put them on a dimmer.

    Thank you Rand - I can see using them for unloading. I'm thinking of some LED interior ambient lighting. I just didn't want to blind anyone. I need to get the boat home so I can start 'fixing' things which is code for upgrading so the wife doesn't realize the money I'm spending. LOL

    What are you guys getting for a top speed?
    I'm at 36 MPH by GPS WOT at 4400 - 4600 RPM with
    5.7L Merc EFI
    Bravo 3
    Not sure of prop pitch. Most people seem to be in the 40's I'm feeling slow.

    You should EASILY be getting mid-40's on that boat, possibly even mid to upper 40's. That, of course, would be WOT (4,800) in calm conditions with a CLEAN bottom, minimal gear, 1/2 tank of fuel and one person. But even with a few people on board and average gear, somewhere around the mid-40's is still expected.

    That’s what I thought. My props are a little banged up so that may be slowing me down a bit. Those #’s are with 1/2 fuel and just me onboard. I might hit 4800 RPM, it’s been a while since going WOT. Conditions were calm.

    If the props are banged up enough that they are slowing you down, they could be doing damage to the drivetrain and/or the engine, as well.

    Even a little bit of bottom slime can have a dramatic effect on performance.

    Not much slime and there is a ding or two on the second prop. I’ll post a pic next time I go to the boat. I have to finish compounding, polishing and waxing.

    2005 280 sea ray Sundancer. Twin 5.0 with Kohler generator with Triaxle 2013 yacht club trailer with
    Twin 5.0 Mercruiser
    New owner of a 2016 240 sundeck. Down graded from a 280 Sundancer so I could trailer with the family.

    One question we have is there was no manual for the head. I was told it has a holding tank but didn't get a introduction on how to use the head. There is no macerator so we will need to have it pumped out. Only got it for the kids to be using in emergency but I have always had a vacu flush system. Can anyone tell me about it? Is it a true holding tank? I do have pressurized water system so I would assume there has to be a tank as I don't have a sink other than for bow and rear spray offs. Seller didn't go over and after looking into I see it's complete different set up.

    Any help would be appreciated.

    Thanks

    FYI, this particular thread is for the older, larger 240SD. While that's not of too much importance for this question, that 240SD WAS available with a VaccuFlush - so it might be confusing. Your boat would have either a simple porta-potty or a porta-potty with a pump out. No fresh water supply, no remote holding tank. Google around for porta-potty... The top section holds water (manually fill it), the bottom (detachable) section is the holding tank. IF you have two lines coming off the back side, then it is a pump out.

    Our boat has the port-a-potty with pump out. You have to manually add water to the tank. Port-a-potty works by pumping in a squirt of water with the button on the rear corner, do your business. To flush, pull open drain valve at front, pump a couple times to rinse, and close valve. Instead of going to a marina with a pump out, we found it easier to disconnect the lines and just carry it a toilet and dump it. We only used it for the kids when they were little.
    Now that the kids are older, we removed it. The bathroom is now a store room for towels, t-shirts, shoes, a large trash can for empties, etc.
