question on the 1st gen pumps

[shendren]

a friend of mine owns a boat with a "210 cummins". he has a pump made by lucas i believe. who is lucas? is this the same pump that you guys have on the 1st gen trucks?... ... .



another friend has a boat with a cummins and his lucas pump solenoid gave out while he was in the middle of lake okochobee. nice and sloppy when he had to have it towed in... ... . he's had this happen twice now.



anyone know anything about the marine version?



thanks. scott.

The POD injectors are from marine use so I will venture a guess they make pumps also. But what I do know is they don't have a few items that are needed for street use.

If they make thier pumps like they do thier electrical systems, no wonder it went out.

We used to call Lucas "the prince of darkness" for a reason. And it's not related to exhaust smoke.

The pump is a Lucas/Cav. There were very common on the 210 marine engine and used for a lot of years.

Any pump shop will have parts as these pumps are on lots of diesels. I had one on a marine Perkins T6. 354 for quite a few years.

If the solenoid keeps failing, I would check the wiring to make sure you don't have "green wire" which will rob the solenoid of voltage.

Also. . your friend needs to learn how to do the manual egagement for when the solenoid fails again... . most of them can be bypassed in the event of a electrical problem.

Hope this helps. . good luck.

ps... been towed in with the Perkins, but never with the Cummins!!!

that was my next question.



the solenoid. i told my father who was on the lake at the time to tell him to find the solenoid and pull it up. i was assuming it was similar to my p7100 pump solenoid. i was told by the "mechanic" that the solenoid was built into the pump? sounds kind of goofy.



any comments?



thanks. scott.

Scott, Can't help you there... I had a pump that was always fuel on... there was an external solenoid that was momentarily energized to shut off the fuel.

My marine Cummins has the p7100 pump... . I know how to bypass that one.

Good luck.

what size marine cummins is that? just curious. all of the marine cummins i have seen so far have had anything but the p7100 pump... ... . ??



thanks

Scott,

See my signature... its a 270 hp. It's a 1999 engine.

I'm not sure what the modern 220 hp engines have for a pump, but 270 and up have the 7100 series.

Some of the older 250 hp have a Nippon/Denso pump, some Lucas/Cav ,and all the older 210 have Lucas/Cav from what I have seen.

You should BOMB that boat engine!! I can't ... . boat won't handle anything more than the 270.

Hey East Coast, tell us more about your boat: make,size and what differences between your engine and one in a pick up. Why is it referred to as the diamond series? Why can't you BOMB it? Are you certain your wife didn't pull the sales man aside and insist he tells you the boat will self destruct if more power is applied?



My dad runs two 318's in his boat [inboard mounts]. It stays on Lake Erie all summer. We will be painting it this winter. Had to pull the port transmission due to leaky seal. The boat is all aluminum manufactured by an airplane company Aluminum Cruisers.



Cheers,

Scott

tell us more about your boat: make,size and what differences between your engine and one in a pick up.

My boat is a 1978 34 ft Mainship... it has a "down east" style hull, which is a semi planing lobster boat style hull with a full keel. It is powered by a single diesel. Originally it had a 160 hp Perkins T6. 354 which is a 6 cyl, turbocharged and aftercooled engine.

I repowered in 99 with a new Cummins 270 hp Diamond performance series engine and a new transmission to handle the power.

Cummins refers to their recreationally rated engines as Diamonds... don't know why, real diamonds are less expensive!!

A recreational engine is rated the highest hp wise within a series... but you are limited in duty cycle to 1 out of 8 hours at max rpm (2600). Commercial is rated for more duty at max rpm, but they govern them at 2500, or 2400 to make up the difference... just a numbers game really.

Old engine got me a cruise speed of 9 knots, a max speed of 11 knots.

The Cummins gives me a cruise of up to 15 1/2 knots and a max of 18 +. This boat gets "squirrelly" at 16 knots, so I really can't use any more power. It's a hull design thing that really can't be changed. I usually run more around the 11-12 knt range anyway. Boat gets good economy there... 2000 rpm, running about 10-14 psi boost at that range... . they say keep it below 15 psi at cruise for max longevity.

Engine has a Bosch 7100 series pump and a "jacket water cooled" intercooler... an antifreeze cooled unit mounted on top of the intake manifold.

A gear driven sea water pump (for heat exchanging) is mounted where the p steering pump is on our engines. Exhaust manifold is antifreeze jacketed for cooling, turbo is jacketed, and there is a tubular heat exchanger mounted below the ex manifold.

Engine has a sea water tubular fuel cooler to insure top hp.

Exhaust is water cooled and 5 inch dia hose w/no muffler.

Oil capacity is 16 qts.

I added a boost gage (VDO via a transducer) and I'll add a pyro over the winter. I also have a S&B air filter. . similar to K&N, but built much stronger, and deeper pleats.

There are pics of the engine and boat in reader's rigs.

Sorry for the wordiness
