I've always thought the 617 engine would be a perfect replacement for the Ford Lehman 120hp diesels that are put in the smaller Grand Banks trawlers. Go for it..post some pics too.

also, on the 240 fw in a 300 motor converted to 4spd, the vibration is in the driveshaft. it needs a balanced weight like a large harmonic balancer to even out the 5th cylinder pulse.

Hopefully there wont be too much vibration because sterndrive engines are pretty much solid mounts directly to the boat .... there isnt much room for give as the drive shaft coming in from the drive must be perfectly aligned with the coupler and gimble bearing

Remember this is a very heavy engine as well. Did you consider a volkswagon tdi diesel ? A lot lighter and smaller for a 17 foot boat. Far more fuel efficient as well.
I really think the tdi engine can product the same shaft horsepower with a chip.This may not even be required as the lighter weight may be an equivelency compensation alone. As for a junkyard engine you are not even allowed to run before purchase. I would question the wisdom of that. Better to find a car that is not roadworthy yet that you can at least do some testing on the engine before purchase. Quite a project as well. No flywheel issues with the tdi but there will be some work because of the modern engine management system. |

As no one has mentioned either of these terms and can't figure out where the vibration comes from I am going to do what I hate, reverse engineer from another brand...
On Fieros... (I know forehead smack) the early years have the flywheels balanced to the crankshaft. On the later year the flywheel is neutrally balanced. Mixing the two doesn't end well. Is anyone aware of whether or not some mercedes flywheels are neutral or balanced to the flyweel? Also, I too have seen 616 marinized motors, just not a 617 with a turbo. |

http://www.vwmarine.com Mastercraft uses these engines in some of their tournament ski boats. The original engine in the boat is also VERY heavy i don't know the exact weight but i will find out. They are both iron blocks and heads, Both very stout over engineered engines. The 3.0 Mercruiser engine also has a VERY HEAVY intake and exhaust manifold combo (prob double the weight of the 617 manifolds). I am sure that there isn't much of a difference in weight between the two.

If you are worried about the heat from the turbo, just install a "Jacket" or blanket on it. Its made from fiberglass or some other non-flammable material that you can wire onto the turbo & any other hot spots you might want to cover. Don't have any links for you, do a Google search & see what you can find. Since most of the MB exhaust system is close together this would probably be the cheapest option. As for the exhaust, a marine water-injection fitting just after the turbo would keep the exhaust pipe cool. Just make sure it's "down hill" from the turbo to the exhaust outlet from the boat.
Also, see if you can find a marine heat exchanger for the cooling. DO NOT try to cool the engine only from sea water - you will quickly ruin it. This is a cool modification! Keep us posted! |

The fun would be trying to puling it off on the cheap in my opinion. Scrounging should not be dead yet. It is harder than it used to be though.

watching this like a hawk. A small mister pre turbo could keep temps under 150 easly. Think 70s jet boat headers
