Repower?

[Cricket]

It's insane the amount of room around our 3406E's compared to the 8v92's and original 12v71's. As far as stringer strength I find it odd that there was an issue with that repower, unless there was a previous issue, or maybe it was the install. On ours the original construction drawing had steel in the top of the stringer between the layers of glass. The magnet didn't find any, must be aluminum then, drilled some holes and nothing. We added steel and then glassed over it, full length between ER bulkheads.

actually the question came from Steve at gregory pool in wanchese. But his information came from the person who was going to do the install. I do not remember his name but he does the installs for Balis and gregory pool, when you see the bammers flying around the beach from Hatteras to Kill Devil he is the man at the wheel. He puts engines in on the side or flyes on the side i do not know which. But when John Balis reckomended him good enuff for me.

Shut them down and they stop leaking.

I don't know the full dimensions of the 12.9 compared to the qsm11 but I have seen engine rooms with the qsm11 repower from 892's and it's night and day.

Horsepower aside serviceability is top on my list.

I have been in a 52c with qsm11 you can play ring around the roses or maybe spin the bottle. Plenty of room eaven with two generators.

i was told that if you hang a picture of an 8v71 on your wall that oil will run down the wall???

 

[jim rosenthal]

That depends on whether it's a photo of an 8-71 that's full of oil, or one that's empty.

Run 'em long enough, and all of the oil on the inside of a Detroit will end up on the outside.

You should see the engine room in some shrimp trawlers oil every where rust a plenty. But they just keep running some guys never shut them down they know how long it takes for the oil level to go down. They just pour 5 gallon of oil and keep going. I ask one trawler owner how many hours on his DD. His answer was do not know got them used but been running them for going on 12 years.They are tuff engines my buddy down the creek been through several cats, Them motors got medal in them none of that aluminum.
They smoke under a load when the bag is full but keep pulling. From the sound i can tell when a injector needs help. I change impallas once a year, What about heat exchangers do they clog. No they are outside the boat next to the keel. There is not a fancy travel lift at our mariner its a railway. Trawlers come there because of the support in pulling the wooden boats. also we are cheap.

Pete, At least one 42 LRC re-powered with luggers 120-135hp if I recall. Also he loved them and
ran around the Bahamas and Florida. At least one 58 re-powered with small Cummins.
Skooch
58 LRC

A good friend of mine did a repower with the qsm11 on a 43 convertible super awesome set up. Great program and decent prices. Tim you mentioned qsm11 in a 52c? I would love to have more room in my engine room, I am comfortable doing mechanic work but having more access makes for better maintenance..

Hi Pete,I own a 42 LRC with the same 4-53's as you have, and have also looked into repowering. I found my best option was the Volvo Penta D5a TA. http://www.volvopenta.com/marinecom...lsion-mc/d5a-ta-118-kw/d5a-ta-118-kw.htmlThey are a perfect fit, got the power you need, you can use the original BW transmissions, shaft and propellers (perhaps increasing the pitch by 1") as wot is at 2300. These are actually Deutz engines and are also sold by Vetus as well. Real work horses, they are not common rails, and their bigger six cylinder siblings are sitting in my town's ferries, pushing 40k hours between MOH. My brother just bought a pair for repowering his GB 36. Good luck
