    Have a 2000 AJ that came with a westerbeke. I just installed an MCCK onan 6.5 and trying to figure out how to wire in the panel. There are 3 wires white, green and black for it but not sure where they go. Also if i try to run it without the panel, just start it from engine bay what actuates the solenoid before the fuel filter?

    Is this the power load or the start panel? Typically on the ac power side, black is the load white is common and green is the ground. Black goes to the circuit breakers, white to your neutral bus and green the the ground bus.

    However, if your not sure, get an electrician, as you can let the magic smoke out of some big$$$ stuff if your wrong.

    As far as starting and stopping, that’s a little more involved...

    IMG_4230.JPG Off topic but why a 6.5 kw genny on a 29 foot boat? Would think a 4.5 would be perfect size wise. How will you load it to 75%? Sorry for the interruption.

    Cause i got a completely refurbished Onan for $2000. What is this 75% you speak of? I have never heard of needing to run a generator at 75% all the time

    Generators are continuous duty motors that need to have a load on them they are jetted to have a load on them if you don’t have a load on them they fowl-out the plugs and run like crap

    If i run the genny i plan on using it for the ac and fan mainly. That should put a decent load on it

    A lot less than you think. In fact, that load is next to nothing.

    We will see i am just worried about getting it running so it doesnt just sit in the boat. I assume its jetted rich for the load purposes so worst case ill have to change so.e plugs if it fouls. My digram does show green ground, white grounded neutral and black conductor but doesnt show where to hook them up.

    Tim, are you adding this genset to a 290 that already had a genset or are you adding one in? Reason I ask is that the boat that already had one will have the transfer switches in the panel. If not, you can still do so but will need to add an auto transfer switch so you don't accidentally allow AC current from shore power and your genset to energize at the same time. I added a gen to a '91 270 DA (similar boat) that was not wired for a genset and instead of using a panel mounted transfer switch, I added an automatic transfer switch as used on RV's. This allowed me to use the shore power input as a preferred source and the genset as a backup source for the AC panel. If you post a picture of your AC panel we can make a recommendation. I have no idea if an auto transfer switch is ABYC approved, but it worked for me and my marina was the one who installed it. Worked great. But haven't seen it on another genset equipped boat. This would help you with the power output of the genset. As for the starting circuit, to do so remotely from the unit. There are remote start panels available for Onan. The one I added was an Onan too. Loud as hell, but for $ 2000 go for it. Please make sure your exhaust and fuel are routed properly. If you want, I have the Sea Ray schematics for the genset install. Great boat, Dan.

    Shoot me what you have timothyberlinski@gmail.com and the boat had a genny installed and does have the panel where you can switch from shore to generator and turn genny on. It was for a westerbeke but if i fogire out the wiring i should be able to make it work.

    Ok i think 1 last question. Here is the diagram i found i am assuming its the top one 120V and not 240 since my system ony has white, green and black wires. So grounded load wire is the black? The top line is white wire and then green goes to any ground source?
