People have bought and swear by this

It always looks easier on a workbench :)

Growing up my dad used to say "They should have to do this when it's 30 degrees outside with only a pair of pliers" - now I get what he meant.

That tool and puller are interesting though. What would be more interesting is if the website provided a way to purchase one...

Has a anyone used the inpeller tool. After hours of struggling the video looks a little too good to be try. Hard to imagine our impellers sliding so effortlessly into the tool. My keyway is blind so the key has to go in first which prevents rotating the impeller during insertion. If there were an easier to service pump I would gladly pay to switch over.
 
Reinstalling my serviced/cleaned/tested coolers this weekend.

Can anyone confirm that the fuel cooler is the LAST STOP before fuel returns to the tank?

or

Will I need to prime the fuel system to remove any air since nothing else in the fuel system was disturbed?

THANKS IN ADVANCE !

seems to me if i'm just pushing fuel back into the tank it will not be necessary to prime anything.

Is this assumption correct?

Foley CAT covers Nj, Pa, De and Md. Not sure about Va.

How has Foley CAT been regarding marine engines?
I called the Delaware office in Bear, DE (no tax in Delaware). They suggested I call the NJ office. Granted, we had a long winding conversation and I may have been speaking to the wrong person. Plan on stopping in as they are only 20 minutes from my house.
 
My transmission cooler wasn't compromised like I thought so I can pay to return it or if someone is in need I can ship it to you....?

Items Qty Price
113-1113 Caterpillar Transmission / Gear Cooler

SKU: MRC113-1113

Transmission gear oil cooler replacement. I've got ZF85 IV units.
Can't find a part number for this in the ZF Transmission Parts Manual.
Searching on the internet turned up ZF Part: 3312107003
That led me to this kit on Seaboard Marine for $395
Would really like to stick close to OEM replacements, at least until I've caught up on all the neglected items from the PO.
Saw the post above for the Mr. Cool cooler. On the Mr. Cool part page here it states "This same configuration is used on Cat 3126 with a ZF Trans as well." I have 3116 engines.
Where would I find the actually CAT OEM part number?
 
I noticed on a cold start today the starboard engine puffed some white smoke for a couple of seconds, port engine does not. Both engines ran very strong for our trip this weekend.

I noticed a very small amount of diesel in the bilge, on the starboard side as well, when we got back to home port. I know it's diesel because we could smell it and I had placed one of those white oil absorbent pads in the bilge to soak up what I thought was some oil during the trip home. If you're facing stern looking into the engine compartment, it's the left side of the center bilge. I looked around for a source but couldn't find a trail. I know this sounds ridiculous but it appears to be coming from the firewall area.

I went ahead and removed the air filters and brought them home with me. I cleaned them with the k&n power clean, they were pretty dirty.

Any suggestions for the white smoke or the very small amount of diesel?

Note, we took on 60 gallons of fuel since our fill up a few weeks ago. We've run the boat two and a half to three hours at cruise so that's a pretty good burn rate I think. I did top both tanks off today before we left to go to home. I also added all of the fuel treatment additives in the fuel management thread before we left Friday. Not sure if any of this is related.

I'd clean up that fuel really well and start the engines to try to trace it. The bilge slopes forward so leaking liquids usually run up toward the firewall. Common places would be the racor (loose plug in the bottom), loose clamps on the fuel lines, secondary filter on loose (unlikely), fuel primer pump (unlikely as well as the engine would run like shit), or the fuel inlet compression fittings on fuel cooler

I wouldn't worry about the smoke. Was it a cold morning? did you run the air intake heater before starting? Ours smoke a little bit while they warm up this time of year, the air is cold in the morning and the water is only 60* so it keeps the intake air very cold until the engine is up to temp

Wait, you reminded me of something, the fuel primer pump on that engine was leaking fuel during the presale engine survey. I've purchased a new one but yet to replace it. I assume on the starboard engine it's mounted on the hull side of the boat?

Hmmmm...

85 outside temp both start ups. I do not know what an air intake heater is, nor do I think my boat/engines have them since I don't see it on the breaker panel. It's literally a puff or two, 3-4 seconds, then all clear. No white smoke from the port engine.

Yes the primer is on the outboard side of the starboard engine. Usually it will introduce air into the system if it’s leaking and you’ll slowly get worse engine performance but maybe not in your case. I’d be looking there first for sure

you probably don’t have AIH. They were only on some boats, although there’s no fuse or anything. You can see the voltage drop when they turn on

3-4 seconds of smoke is nothing to be worried about especially with no other issues. They’re certainly clean burning engines but they are oil burners at the end of the day :)
 
I have cleaned many gas engines with a good degreaser and a water hose. I know what to not get water on. Cleaning these CATs is new to me though. Mine do not look bad, thought I'd like to clean them up so I can see any leaks.

Is it safe to degrease them and use water to rinse off? Anything I should cover with plastic, not get water on/in?

Thanks
 
Thanks, the challenge for me is I don't really know what's electrical on these engines compared to gasoline engines.
 
If it doesn't have any wires going to it, it's not electrical.
Sorry, had to.
Ha, I thought the same and almost volunteered that in my reply to not appear as stupid as I am.

I was thinking more about the parts that are new to me, for example the turbos. "Do NOT get these wet" kind of thing.
