How is your A27 powered

[tego]

The VW Pathfinder was/is a very reliable engine and would power a 27 well. If you're in a hurry, you have the wrong vessel!

I have the Nissan in my 87' SC, I assume its the original. I've been thinking about a repower so when its time I know which engine I want to go with. The 100hp range is sounding right. I've heard of the Yanmar and Westerbeke in that range. Any other makes? I was wondering about a 4cyl Cummins or Kubota, any thoughts?

When the time comes, you might want to think about a rebuild of your Nissan - Much more cost effective

I'm in the process of a repower with a 100 HP Yanmar 4JH3-HTE and I can tell you it's a VERY expensive process, even if you can do 100% of the work yourself

I bought my engine newly rebuilt direct from a Yanmar distributor and it included a new transmission and a new instrument panel. The engine was $10K and by the time I'm done, the complete conversion will likely run me close to $15K . . . . and this was using a rebuilt $10K engine. A brand new 4JH4 (the current version of my 4JH3) would have been at least double that price

I paid $15K for my boat ten years ago and am now investing another $15K in it plus a few hundred hours of labor and in the end I'll probably have a boat I could realistically expect to sell for . . . . about $22.5K

Is a Nissan rebuild looking any better to you?

I definitely understand what your saying but how long will Nissan parts be around? Right now there are parts I can't get fortunately they were gaskets or parts I wasn't ordering as I'm seeing "no longer available" a lot as I have looked for parts. Granted this is a new boat for me(learning curve) and I had my first breakdown in the boat which I'm fixing at this time. I guess I'm a little discouraged about the availability of parts. Hopefully when the boat is up and running I will get some confidence back. I appreciate your input because this is what I am looking for.

The injector pump and injectors can be rebuilt by most any diesel engine injection shop. The fresh water pump *may* be the same as the one used on the gasoline engine

Ebay is also a great source of NOS parts. By looking for Peugeot Diesel parts vs "Lehman" I have found nozzles, water pumps, alternator brushes etc etc, generally at really bargain prices. I have built a good set of spares for my engine so I dont worry quite as much about a breakdown as I used to.........

I did try rockauto but I used an 83' maxima and didn't have any luck. I'll give them an other try. The engine did run fine before the IP belt slipped. So I do know about the belt maintenance now. There is an ld28 forum that has been really helpful. Thanks for the advice. Stocking up on some spare parts are also in order. I do have an extra belt and pulley tensioner now.

When looking for engine parts for a boat, many times the year sold or boats model year is'nt the year the engine was made. Marinizsed car engines can sit around for some time (years) before they go into a new boat. Look for an older year car but with the same engine specs when searching parts

Interesting. What year is your A27 and do you know if it came with the Volvo, or has it been repowered?

Volvo Penta TAMD31P

Our '85 Express was repowered with a Volvo-Penta TAMD31P (diesel) prior to our acquiring it this January with 723 hours. It's turbo charged 4 cylinder and rated at 130 HP - though I've seen the same engine listed as slightly lower and higher. I can get a solid 13 knots, but that's not really very realistic or fun - it's darn noisy and uncomfortable if there is much of a sea running. We have settled into a comfortable 7-7.5 knot range that does us well and 10 if I'm in a hurry - starts getting noisy though.

We've put a little over 60 hours on the engine since January. I can't give an accurate fuel burn at any specific speed as I usually vary it depending on the conditions, etc. I estimate 1.5 gph fuel burn and have been pleasantly surprised to be a few tenths of a gallon below that when refueling.

FYI Volvo used the same Peugeot base engine for a number of years for one of their engines..... Can't remember model. The base engine is very solid it the part
S around it that need maintaining.

I just received the following from Bob Bain.
Hi Dennis, Good to hear from you. We're still here, have the largest stock

Dennis adds.
While Bob Smith of American Diesel is an old friend, I don't think they are
trying to keep on hand parts for the 4SD61 Puegeot based marine diesels. Bob
Bain ALWAYS either had the part I needed or could suggest an alternative
source. You can't go wrong starting there.

How about the 100 Westerbeke? I see that some 27s have this engine?

My 27 has the 100 Westerbeke. I have no trouble getting filters and it starts and runs like a gem. I cruise at 6.5-7.5 at between 1800 and 2000 rpm. I can go up to 9 knots when not bucking the tide but at 2500 the engine is much noiser. At 1800 we can cruise a a nice quite smooth ride. I like having the extra horsepower for bucking tide or seas. This engine transmits little vibration at cruising speed. The bulk of the engine does take lots of room.

[mboatworks]

I have a 100 Westerbeke in mine. Runs really smooth and quite. But it is a 6-cyl, only putting out 103HP, so it better run smooth. Probbaly way they last so long, they never get worked hard. I need to test the tachometer to see how accuarate it is, but I am guess at 1700rpm, and 7-kts, is its sweet spot. The fuel burn is about 0.7-gallons/hour at that speed. By some rough calculations, it is only using about 40HP at that speed.

Anything over that and it just plows water. I think it would take about another 20-HP to get it to start planning.

The downfall, it weights 750lbs, and is the same size as a yanmar 6-cyl, that delivers 230HP. So, it takes up a lot of the engine compartment, and weights a lot, for that relaibility. I have to pull the engine, to even get the waste and water tanks out.

Hourmeter was not working when I got the boat, but I am guessing there is about 2500 hours on the engine.
