Your smarter than you look. LOL. Great advice as usual.
Concerning pieces of rubber, I often wondered why no one has come up with a faulty large opening screen (perhaps 1/4 inch) totrap the pieces before the heat exchanger.
I considered the Speedseal kit, but didn't pull the trigger for some reason. Any bad experiences with Speedseal?
I've been tempted by the Speedseal kits as well. It certainly seems like it would help to reduce the number of bolts/washers/tools dropped into the bilge.
We just received our new Speed Seal kits and will be installing them and making a video. I've always wondered about them, and it wasn't until I broke a couple of those little screw heads off trying to remove the cover that I finally decided to "upgrade".

Most look smarter than you and all look smarter than me. LOL
Ted you are of course correct but that requires you remove the end cap of the heat exchanger. I'm looking for something more simple. What Scott has seen might be the ticket.

I had a pair of Cats that loved eating impeller blades, they ended up some place in the heat exchanger and only when it would overheat could I find them by pulling the heat exchanger. The Cummins seem to all collect at the end cap so it's easy to get to them.
I am thinking the first stop on a Cummins is the aftercooler??....then the trans cooler....THEN the heat exchanger. At least that is how it is on my Classic B series.
I have the SMX pumps on my boat. So I change every 2 years. It is NOT a fun job on either engine. It is easier to pull the pump and do it rather than jack around down there with those little screws. And guess what??? I carry an entire spare pump assembly with a new impeller in it. Suck on that Ted!!!!
I changed just my Cummins SMX pumps and their impeler. I think smx impeller is considerably more flexible / softer rubber than Sherwood. do you have the experience to compare smx impeler vs Sherwood impeler resistance?
If you are changing the Yanmar impeller, make sure you get the "newer" style that have the threaded core. I went to buy a set to do my annual change and the dealer wanted to sell me the old style. I asked if he had the new part and he said yes. The threaded impellers are much easier to remove and install.
I have also bought new impellers that had cracked vanes, so now I inspect them when I buy them.

I have both a new pump and spare impellerS.
My 6CT300 Cummins doesn't have an aftercooler.
But you do have more engines to service than I do. So I guess you win.

If I only had one engine I would carry lots of spares but having two I can get by with fewer spares. Further, if my engineroom looked like yours I would never start my engine. LOL
Well damn....I have no clue of the different iterations of the C series Cummins. That is very interesting they have a non aftercooled version at 300hp. Probably a wonderful Trawler engine. I was just on a Selene 57 today with a derated QSM11 at 450hp....probably a similar proportional deal!!!
Hi Ted
I've been considering John Deere for a new boat. Do you have any problems find parts?

Yes, but then I remember where I stored them.
No problem finding parts. Lots of sources besides the marine dealers. The marine market is a very small portion of what they build the motors for. There's a big market for most of the consumables like oil filters and they use standard marine parts like raw water pumps.
Ted
Likewise no problems finding parts & spares for my 1996 6068T. I bought and installed a new raw water pump last year. Very easy replacement.

I just made a run out to the Farallon Islands this past weekend. Taking out fresh scientists and supplies and bringing back tired scientists and compost! I staged the boat in Sausalito for the run - I"m based out of Redwood City. How about you?Richard where are you these days in that cool boat of yours?
