If this is the original luhrs 32 I have spent alot of time on one that was repowered with twin yanamr 4 clyinder diesels at 140 hp each and the boat cruised at 14 kts and topped out at 16- 18. This is kind of underpowerd and i figure the 240 hp yanmars would probably push the boat just fine.

I put 240hpYanmars in a 28ft bertram.The boat runs 22-23 knots cruise.nice motors,good gas mileage. Plan on spending some money with trans,shafts,ect ect. 80k-90k sounds about right.Plus if you do the conversion make sure they are perfectly aligned and straight. Ours weren't and that was also costly. It was rewarding watching the transformation.good luck
Greg,
Awesome pictures. I have found the 240hp and it isnt much bigger or heavier then the 140hp. I look into all the running same direction engines ect. Some one said I could just run a tranny reverse or something, is that what you are saying it wont handle? Or is it that I will have to find new transmissions as well as the engine and use the original v-drives. Not that there is a problem running same direction engines. I rekon if I can use the same v-drive, same shafts, same tanks, throw some engines in and new props I can do the repower for a good price. Hell I saw a yanmar 240 for sale for 1250 bucks, fresh rebuild on a 628 hr engine. I put 1 1/4" thru hulls on it some years ago, you think I need to go bigger then that?
Im still a bit confused on where the 80k-90k price tag comes in at. I can buy a pair of brand new engines for less then 30k and it surely wont cost me 50k-60k to install. Im not sure if I am missing something here or not.
Hag thanks for the heads up about being aligned. I was looking at that last night and trying to figure out what I am going to machine up to makes sure they are dead set straight. I was also looking at how hard it would be for new engine mounts, whihc is about as basic as it gets so it will help make the process of making it straight a little easier.

yea the v drive wont handle the load in reverse so my friend has 2 left hand props and handling isnt terrible it is just a little different while maneuvering, especially when reversing as the boat will not back down straight. I would recommence just changing the gearing on one of the v drives to solve this problem. also if i am right with the 140's my friend used a 3 blade 15 by 15 prop .
The 140 and 240 are the same engines. I saw that Athens has a pair of factory 4lha 240s for sale. $42K for the pair. $1250 for a decent running 4lha?? If true better buy a lottery ticket cause you are lucky today!
The yanmar 170 thru 240s in the LH series were 4cyl not 6cyl. I had them both in different boats. They are not sold as new today because of emission problems but they can still be found-they aren't cheap however. You should get the 230 to 240 if you are going with Yanmar. I had a 29 ft Aquasport Tournament Master with the 240s and fully loaded 23knots was cruise. If you are content to run at 14knots than the 170 to 200 would do, but for all the effort you are expending I would go as big as I could fit and afford.

A friend had a reputable machine shop install a new volvo diesel a few years back, around 250 HP or so. I think the pricing was about $20K list for one new engine and $5K for the basic install. It was an older boat and once they opened her up in really needed another $10K in parts and labor to get everything shipshape. Total of $40K for the entire job.
.......Ive definately gone overboard with my bilge blowers, lifting hatches and all that in the past. I am just trying to minimize the danger. My kids are older now and I would like ot take them on some of the more serious fishing trips we do. ............
I think you're overstating the "danger" of a gasoline fuelled boat. Diesel is safer, but a properly maintained and operated gas powered boat is pretty safe.
Greg,
I will keep that in mind and see what it takes to change the v-drive gear, cant be too hard im sure.
Raymond I did happen to find a site that was a little informative on the 4lh- 240 and see that it is a 4cyl. My mistake for improperly mentioning that.
A decent used running pair will suit me just fine. I surely dont need new ones at 42k for the pair. But if I did happen to find some good used ones for fair price then I would definately be in on the project.
I wasnt trying ro make such a big deal on the danger part, although I do think about it now more then ever since I have more of my family on board. However I still think mileage and fuel price wise is a pretty good argument. And lets be honest the boat has been fine all this time. I believe it is well maintained, and everything that needs to be replaced on a normal schedual is.

hey im just curious of what your fuel capacity is and how it is set up. my friends 32 has 120 gallons and it is in 2 tanks along the forward engine room bulkhead. and he is looking to put more fuel but cant figure out where to put it
Greg,
I have 2 tanks and they sit just aft of the main salon bulkhead in front of the v-drives. They ae actually in the engine room. I will try to fnd a decent picture of the one I removed. I measured each tank with a tape to get an idea since I could never figure it out by measuring. I believe each one is approx 105-110 gals.

Awesome reputation among his readers.
A posted a thread on his site as well. I havent heard anything from him as of yet. I will look up his business tho since i am in So Calif.
Greg there seems to be a lot of people against this sort of repower. Again I am not exactly sure why since your friend is proof of doing it to the same boat. Am I wrong in thinking it makes sense to do?
Does you friend have any pictures of his engine bay after the repower? I have looked at many '73 Luhrs so I know what they look like when they came with the Chrysler and with the Perkins.
Most replies seem to insist on changing the prop shafts and struts but I honestly dont see why. If it was a prop size issue well heck I could stick a 24" prop on my boat and still have room. but if your buddy spins 15x15's then I know I will not have to go 24's. I think I am more confused on if I want to do this now then when I first started. Thank goodness it is kindda winter.

I think it makes sense because that luhrs at its cruising speed burns very little fuel with the yanmars and i would try to get some pics of the engineroom but to put things into perspective the owner put a 4.4 kw generator in the space between the engines and there is s still adequate room to move around the powerplants. remember the cryslers were v8's and the yanmars a inline 4's so there will be alot more room in the engine room

The Yanmars weren't listed on the Seaboard Marine site, but I would try giving them a call. Their site says they specialize in repowers for small to midsize boats. That market's pretty dead right now, so they would probably be looking to get rid of them if sickcat is right and they actually have them.
my friend was able to keep the v drive configuration and use the same gearbox and shafts. only one problem is beacuse the chrislers turned opposite ways and the yanmars turn the same way he has 2 left hand props because the v drive gearbox cant take the full load in reverse. one thing to considder is putting a bigger thruhull for the water intake for the main engines. will be happy to answer any more questions. idle speed is not a problem since the yanmars are high revving diesels and the boat floats pretty level with the 140's so i cant imagine the 240's or 200's weighin much more
greg
I think I owned that weekender years ago.Or a sister ship.
The boat had Perkins 6354 160 hp diesels and walther V drives.
It was a max cruise speed 16 knots.
At the time, I wanted badly to repower with the 17o hp Yanmars.
I remember thinking 18k cruise was a realistic goal with the 2000 pounds weight saving.

I live in Trinidad in the southern Caribbean and my friend bought the boat about 5 years ago and it had twin chyslers but he put the yanmar 140s in the boat and then shipped it down to Trinidad, so it is highly unlikely it was the same boat. but for their size they are great boats with a lot cabin space
