Is there any disadvantage to powering a 28 TE with a 370 Cummins?

[Mae T]

My question would be why would you want to re-power with a Cummins.

If it's because you have a peninsular I can relate my experiences with that product and assure you that it is a great engine.

When I purchased my Albin 28 TE it had a peninsular engine. It was hard to start, it ran hot and I developed an oil leak. All three are easy fixes and you will have an outstanding engine for years to come.

First of all it takes two fully charged batteries to start the engine. I now have four batteries. Two are designated starting batteries and two are house batteries. Also, the glow plugs need to have a new timer so that they stay on at least 10 seconds on a cold start.

Second of all it "ran hot". I tried everything first before putting in a larger heat exchanger. Took out the original one, had it cleaned; changed the pulley on the water pump to increase the gpm; and finally changed the heat exchanger to a larger capacity and the boat has always run cool since that time. I got it from the same place that manufactured the original heat exchanger in Washington.

The oil leak is a real problem. The engine has two remote oil filter lines on the bottom of the engine. In a automobile this is where the oil filter goes. There is no room in a boat for a oil filter under the engine and therefore there are remote oil filter lines. I developed a leak in one of the lines two years ago and replaced them. It happened again with almost disastrous results since a high pressure oil leak can pump the engine dry.

Two simple fixes. change to stainless steel lines which you can purchase from a company which manufactures airline hoses and fix the stuffing box and make sure there is no salt water drip which can create a fine mist and cause corrosion in the engine. You can have dripless packing and if you don't believe in that use a hose, or shield over the stuffing box to prevent moisture in the engine.

These are relatively simple measures to keep a peninsular engine in good shape for many years.

I think it will be a very tight fit. I repowered with yanmar-it is very tight, and the Cummin's is a longer lenght.

The Cummins 370 is a tight fit in the engine box model. Because of space constraints it was not available in the Flush Deck. It is certainly easy to work on. I love my workhorse Cummins!
Remember as I am sure you realize at repower with a different engine the project grows. Transmission, shaft, prop. The entire drive system will need to be replaced.

You can go online and get all the Cummins measurements then do your own research to determine if/how it will fit.

Thanks for the installation feedback. Does anyone have feedback about performance; speed, reliability and efficiency?

[Pitou]

The link below will take you to the Cummins web-site with PDF links to Technical Specs. including installation drawings, performance curves & datasheets.

Thanks again, I was hoping for actual experience with a 370 in an Albin 28 TE.

The Cummins link is right on as far as performance, fuel usage, etc.. What kind of "actual experience" type questions are you trying to answer for yourself? I'd be happy to share any specifics to any questions regarding this engine. I have been running my Albin w/the 370 for 5 seasons. Remember for $25 / year there is always lots of info on Boatdiesel.com with Tony Athens ...... the true expert.

With a normal load of fuel and gear for two people, what are your actual cruising speeds at say 2400, 2600 and 2800 RPM. What prop are you using?

Thanx,

Fully loaded .... a dozen fishing rods, 2 heavy tackle bags, stocked galley, tool bag, 130 gals of fuel, 36 gals water, 4 person solas liferaft , gas grill, outriggers .... you get the idea PITOU is loaded with gear.

2200 rpm @ 8gph = 16 - 17 kts, 2400 rpm @ 9.8gph = 20-22 kts, 2600 @ 12.2gph = 23-24 kts, 2800 @ 15.7gph = 24.5 - 25 kts, 3000rpm @ 20.1gph = 26-27.5 knots. The higher speed is less than 3/4 of a tank of fuel and favorable tide and wind conditions. Rarely do I cruise higher than 2400 as the fuel consumption efficiency curve vs. speed gained is not favorable in my opinion. The 370B is not to be run at 3000 rpm for more than 1 hour in 8. Remember these are recreational power plants that are expected to average no more than 300 hours on the engine per year.

The sweet spot for these boats, as I think most will agree, is a cruise at 16 - 22 knots ... burning between the 8 to 10 gph range. Not to say when we need to get somewhere a short cruise at higher rpm we don't do it.... ie; out running a t-storm, catching a tide, etc.. Depending what your running now for a boat the slower cruising speeds may possibly be something to aquire a feel and desire for. This past spring a friend purchased a 35 ft. boat with a single 450 Yanmar. He had a hard time adjusting to slowing down and enjoying the ride. After his first season he now enjoys his 20 knot cruise with great fuel economy and no spilled cocktails. He is looking forward to next year.

The engine is easy to work on ..... oil changes, coolant changes, commissioning and decommissioning. The Cummins 370B was a search criteria for me when seeking out my 28TE. I hope this info gets you closer.

Seasonal Average : 3.16 gph, trolling, cruising, cocktailing.
I'll get back with prop size, pitch and cup. I need to check my propscan paperwork.

I have to second this. I have run Cummins 6BT(A)s in boats (repowered with one once) and pickup trucks for many years. They are dead simple to work on. You can do just about anything yourself including setting pump timing, where many engines require very skilled technicians. Parts are also inexpensive, esp ones common to the automotive industry...for example you can buy a set (yes 6) of brand new 370 marine injectors on ebay for $325.

I was looking and now own a 2000 TE28 with a 370 Cummins. Does anyone know if there is an alternative source for the Cummins ECU preheat # 3921277?

Thanx,

Mark,

In the normal course of our work, we remove most of the Pre-Heater Circuits from the new Cummins B's & C's, as out here, they are not really needed.. If cannot locate what you need locally at a fair $$, drop me a note..

By an alternative source, I suspect you mean purchasing elsewhere than Cummins. If this is what you are refering to, try your local autoparts corner supply store. After 7 seasons my pre-heater is still on its game.
