    I don't think the one I worked on had multiple charger breakers, plus we knew which one was tripping. If you only have one battery charger, just figure out which of the two is in use... There is no breaker for #2 so its got to be #1 or #3. In our case it was the breaker on the right side, 3rd from the top, marked #3 in your case.

    Hello all, i know this could open a can of worms but has anyone with V drives changed props to 4 blades? if so please let us know your motors (350, 6.2) actual difference in use and economy as well as cost thanks.

    Mine are 4 blade from the factory. Can't really help you with any numbers though other than I top out at about 33 MPH @ 4800 RPM.

    According to my parts manual (same one you're looking at I assume):
    1752165
    18x19 LH, 18x18.5 RH (don't understand that)
    But that's a 3 blade part number

    or

    1851049
    18x16.5
    4 blade part number but not for my HIN

    Mine is definitely 4 blade... got pictures to prove it!

    i believe it has something to do with rotation of engine/transmission to even propulsion.

    So this past summer I started out thinking of a 260 Sundancer (new or late model) and quickly gravitated towards the 280 after looking at both side by side. I am now thinking 310 late model however one without a generator. Just wondering how often are the generators used and if a 310 Sundancer to marketable without.

    Why would you want it without the generator? We use ours for A/C, microwave, vacuum cleaner, etc.

    It would definitely reduce the resale value.

    Generator is a must-have in that boat.

    I think it kind of depends on where you boat. We boat on a large inland lake and a generator was on my "want to have" list. We ended up with a 2007 310DA with a generator, but we don't really use it that often. Ours didn't come with the sound shield and the admiral thinks its too loud, but even if it was real quiet there's only a handful of days where I'd run it continuously and only for cabin air conditioning.

    We do run it for meal prep in the microwave and for firing up the cockpit grill (which we use every weekend). There are a handful of days where we're anchored out long enough that I run it to fire up the battery charger.

    I think if you overnight on the hook a lot or pretty much need to keep the cabin air conditioned because of your climate, then it's probably more of a necessity. For us it's more of a luxury.

    When I was looking for a boat, I had most brokers I talked to actually try to convince me to avoid generators. I can kind of see why -- it's another engine that needs oil and maintenance, and unless you're away from shore power for 12 or more hours at a stretch, you can get away without it.

    I will definitely want one on my next boat, but I will want one with a sound shield to cut the noise. I actually looked into adding a sound shield, but it's hard to justify the expense relative to how much more I'd actually use it.

    I had a 260, now a 310. Big difference. A 310 with a Genny any day.

    Fellas! Has anyone had a custom built boat cover for your 310? Looking to have one built. Suggestions/ideas welcome.
    I’m tired of paying top-$$ for shrinkwrap for a one time use.

    I bought a used "winter cover" (www.fishercanvas.com) prior to last winter. Technically, it's for a 330 but since it would fit so I went with it. I'm happy I did as it did a great job of protecting the boat from rain/(little) snow/etc over the winter months. It's heavy and cumbersome but you really only deal with it a couple times per year...

    I agree that the genny is LOUD. I installed a sound shield and a two stage muffler. This cut down the noise enough that it's not a bother. We use the genny every time we go out to run the AC or heat depending on the season. Could not live without it.

    Jim T - Do you have pictures of the sound shield and muffler?

    What kind of sound shield did you add? I did track down the part number for the original Kohler sound shield as well as an aftermarket option, but there's nothing cheap or simple about either one. If I recall right, the Kohler shield is stupid expensive, and the aftermarket one strongly recommended adding a base for vibration damping underneath. I think I guesstimated the labor of installing a sound shield doubled the price, especially if the generator had to be hoisted out.

    I'm not sure either choice solves the other noise problem, the bilge blower being pretty loud, too. I suppose there's a solution for that, too, involving an aftermarket blower that's quieter. A two-speed blower motor would also make sense if you could use it on a low setting with just the generator.

    All too complex and expensive for how much we use it. Even if it was dead silent, I can't see where I'd get a ton more use out of it except for a handful of days where it was hot enough that cabin air conditioning would feel more necessary. The funny thing is it's pretty quiet if you get away from the boat, and actually not really that bad inside the cabin itself, which I suppose was the major design criteria.

    Part of me thinks that Sea Ray could probably re-think generator integration to make them quieter, especially when a 7kw portable Honda inverter model is rated at 60 dba.
