Generator + other planned mods

We had a generator installed. I inspected it on Friday. A few things need to be done at the time of launch and the system needs to be water tested but it’s in. With everything it came to just over $8,500.

My mechanic at Skipper Buds (four wins dealer) in Oshkosh worked with us, giving us a great rate on labor by having this done in the off season. The labor came in at just over $1,500.

The generator was $5,400. The rest of the money went to other parts like thru hulls, sea cock, sea strainer, ship / shore transfer switch, remote start, battery cables, water muffler, fuel filter + more.

I asked them to not install a 4th battery bank. This was my request. We are using the dedicated starting battery for the port engine as the starting battery for the generator. This saved money, space, weight and maintenance. If you study the redundancy built into a tri-bank system with isolated starting battery the risk of having all batters drawn down to nothing are minimal and unlikely. More likely you will kill half of the system and use one battery to start one engine then the boat has a pre-wired emergency jump system that by depressing a switch at the helm seizes the batteries together allowing you to start the next engine.

The local Sea Ray dealer who is not on the water like my marina wanted $10,500 to do this same install.

This is a low RPM quiet 2 cylinder Westerbeke MPV3 unit that produces 25 AMPS / 3000 watts. We should be able to run the A/C + microwave at the same time. No sound shield needed.

Come spring I plan to post photos and a video.

Our plans are to sleep on the hook or pulled onto the rivers shore even more often in 2008.

I have a few remaining projects. Some will spill into 2009 / 2010.

Sooner – get and cut to fit memory foam as a topper for the V birth where the admiral and I sleep. Something we can pull up easily to access storage under the 3 forward storage compartments.

Sooner – get a small telescoping ladder that will fit in the stern storage locker. This is for easier boarding via the bow at beaches on the river.

Sooner – get something to hold water ski’s and kneeboard between the generator and the engines in the engine compartment to free up space in the cabin and the cockpit and make things less cluttered.

Later (by spring of 2009) – convert the VCR/TV to a flat screen unit with a DVD player and digital tuner. I found a unit that will fit and talked to someone at the factory. Folding units are expected to be out by next spring so I do have an idea of getting one of those. The present unit is attached to a thingy that pulls out and can turn ala lazy Susan. If we get a folding unit similar to current portable DVD players we could add a storage shelf above the unit.

Later – Convert the stereo to something with a 3.5MM input for mp3 players / ipods etc. We can use the cassette to 3.5MM adapter until then. The issue is I have remotes at the helm and stern; a external amp and external multi-CD player and I don’t want to loose these. I will need to see if I can convert and still use these features or I will not make the change.

Much later (2010/2011) – Get a tri-axel bunk trailer with electric brakes. About a $7,000+ item if new.
 
Doug, as already said good luck with the mods...But don't you already have a trailer?
 
Doug, we keep our 280 on a trailer off season near the marina. Works great for us as it allows us to winterize easily as well as spring commissioning. Since the boat spends so much time on the hard, keeping it secure and safe on a good trailer makes sense. We then pull the trailer to the yard when we are ready to launch, pickup the trailer later that night and bring it back to the house...

The funny thing is that EVERYONE who sees the 280 on the trailer in our yard comments on how *huge* that boat is... we don't get that same reaction when it is in the water though...

Genset will be great for you. (Aside, just read in the paper today that 4 young guys (19-22) died in a home in PA where they were using a generator in the basement to power an electric heater...no other heat in the house... Don't forget the co detectors.. I recommend to my friends that they use a spare batter powered co detector in the cabin.)

I'm glad I read your post. We have a 94 290 with twin 4.3's and a genset and she is very stern heavy. Ours has 4 batteries 1 dedicated to start the port engine, two for the house and to start the starboard engine, and a dedicated generator battery. I was going to post a question to get opinions on eliminating the dedicated genny battery and using 1 starting battery for both the genny and the port engine. Any savings in weight is a good thing in my book.

Would you cover the foam with something? How thick of piece are you using and where are you storing it when not in use? Our fill in peice is forever sliding around and off and out, we don't care for it, etc.....
 
Nice addition. The battery solution makes good sense. When your house battery dies, you should replace it with 2 golf cart 6 volts, so your genset does not need to kick in to charge a house battery running your 12 DC stuff. I'd love to do the same some day. We'll see how the inverter works out (won't need AC much). Are gensets like inverters where they are most efficient running at 80% full capacity? How many watts is the AC, hot water heater, and microwave on your boat?

What was the price differential between a 3Kw, 4Kw and 5Kw genset? I imagine the labor would be the same, so why not go with a 5Kw?

Boy, I don’t know the answer to most of those…..but……I never looked at a 4k. Actually, who even makes a 4k gas unit?

3k vs 5k – the generator was only about $400 more.

Labor difference was $2,400 more. So total to move from a 3k to a 5k was $2,800 jump in price.

The 3k MPV did not require a engine removal to be installed. Hence the big difference in labor.

Not sure yet. I think we will just leave the topper lay there. We leave the forward table down all the time.

Our center piece is held in place via snaps.

I guess I could roll it up and store it in the mid birth if I wanted to.

I think my wife plans on making a cover similar to a bed pillowcase.
 
I got an estimate at the boat show to have my v-berth redone with a firmer foam and some Ultraleather like cover to match the dinette for $2,000!!! The large price, they said, had to do with the cost of oil. I'm sticking with the flimsy mattress Sea Ray gave me for now. I've got that fold-up into a sofa v-berth, so it is not as simple for me to get one-piece of memory foam and cut to size. Still looking.
 
Presentation - Those mod make sense. Hey I like the one about putting something in the engine compartment for a wake board. I thought I was the only one crazy enough to use a larger boat to pull the kids toys. Someone said it must cost alot of money for fuel and I should think about getting a smaller boat to pull stuff. Does anyone else use there 28+ footer in this way?
 
I was able to remove my Westerbeke 45BCGTC from the boat by just removing the starboard engine's exhaust manifold. That might or might not work for you.

Generally one sizes generators so that you run them at about 70-80% of capacity. Running the engines with a very light load does them no good.

Best regards,
Frank C.
 
I like the idea of making a pillow case to go around the outside. This might be a good surprise for the admiral. I bet I could get an upholsterer to make a cover to match the boat.

Actually, it is the admirals Christmas gift to the captain. I opened a box and found a note where she said she would do this come spring.
