Cat 3116 350hp & TwinDisc MG507A

[Field Tester]

Both engine and gear have 1200hrs. Engine has panel included and Walker AirSep. The engine needs injector seats as I developed a condition this year where I was getting air in the return side above 2200 RPM. I have decided to repower rather than fix. Since I have owned the boat, I have always had oil sample testing done right up to the last oil change, and have documentation of that.

The gear is a 1.5:1 ratio and is in perfect condition. I'd hate to sell it b/c if you know the gear, you know it is barely broken in with 1200hrs! Unfortuately, my repower requires a 1.77:1 ratio, so this needs to go. I am asking $4,700 for just the gear. A new 5075A (which is what replaced the 507A goes for close to $10K). If anyone has either a 507A or 5075A, please let me know!!

Do you have an idea on how much it was going to be to replace the injector seats? Are they replacable or do you need to ream them, if i recall correctly i believe they need to be reamed with a special cat tool.

 

[pugsley]

they can be reamed out a couple of times before they have to be changed.

you'll be skipping along with this setup

cat has a special too to take the seats out, it's not real expensive if it works correctly.

Field tester.

Can you pm me your number. I would like to talk to you about your engine

 

[F/V First Team]

Can I get a photo or two of the shifting bracket on the transmission? I need to fab one up and would like something to go by.

 

[Field Tester]

Sure, I took it apart because it interfered with the engine removal, and but I will take some pics this weekend and describe how it was mounted to the gear.

 

[F/V First Team]

Awesome, thanks.

Out of all the parts this one was missing that's the only one I couldn't track down.

 

[Field Tester]

Sorry it took so long to reply. Haven't been around the computer much. Here are some pics of the bracket for the shift cable. The bracket uses the 2 bolts that hold in the shift lever, and then the small piece of angle screws to the larger one.

 

[F/V First Team]

How did we make out with that shifting bracket photo?

 

[Field Tester]

The above photos are of the bracket. Is that not what you were looking for?

 

[F/V First Team]

For some reason that post didn't show up for me, but now I see it.

Thanks

Wish it was in the budget to repower!! that engine will definitely go for that price!

 

[Field Tester]

Engine only.

Last chance if anyone is interested! Engine will be sold to a rebuilder next week for $3500. It's up for grabs to anyone here for the same price. I'd rather not go through the hassel of shipping it down south if I can sell it to someone closer who needs it. I know the rebuilder is going to make a few bucks off it, and I'd rather see someone here get something they might need. I have to get it out of my garage to make room for the new motor, so it has to go one way or another. Gear is off, engine is on a pallet and ready to go. Could be a decent rebuild for someone!

i have a friend that just asked me last week if i knew where one was, i will tell him about yours tomorrow. is that rebuild hours, or since new??

 

[Field Tester]

Thats original hours. Not sure if it needs a total rebuild, but I'm told it's best to do it right.

 

[pugsley]

is the motor in montauk?
