Marauder 19

for those that have been following this thread titled "what model is this?" i have started a new one.
got her home tonight. needs motor and trans (eric...gonna need help here) the only parts under the doghouse are the turbos,water jackets,intake manifold and a carburator. will get more pics when i start to get all the stuff unloaded.

Bill,
That is too COOL!!! love the dash!   18 pitch!.... what did it have for power?    What year is the boat? What are your plans?

It probably came with a 440 or 383.
The trans was a VelvetDrive 72c (5" coupling)

The prop was made in Dec. of 1975

And appears someone had it re-pitched to a 13x17

you gonna show that tug or do you want to get it running troublefree?

eric

Probably not going to show it....but do have access to a 440 chrysler motor. any ideas what it would cost to get the trans and related items to bolt the two together? thanks

i see you have a righty, that may complicate things a bit, unless you go with a 1.23 trans

If you go with the 351 power w/ 71C you simply change your 5" coupling to a 4" coupling.

so it is a righty...did the 72 turn correctly with with what i assume was a right hand motor?

just sayin, you need a righty nopower motor,
you can spin the warners either way by simply indexing the pump, but forward position on the shift lever must make the boat move forward.
if you do come across a lefty nopower and want to keep it flat in the boat, really the way to go would be with a 1.23 pcm, then you can utilize the right hand prop and keep the lowpower plant level. the ACBS never looks at the tranny's anyways

not in a boat, it doesnt make sense nowadays unless it puts 100k price tag if all original, which it wont, you can put a small whether a Ford or a Chevy in there and make the same power and run lighter. I really love seeing the older boats with updated power, I look at it this way, in these boats always at the time got the best of everything power wise going into them, why revert and go backwards, move forward not backwards. if the engines of nowadays were available back then, they surely would go into the boats.
aint nothin better soundin than a 426 hemi

Twin turbo 440 probably made that thing porpoise like a *****, the tabs were likely an effort to tame it.

Quik -   Turbos work on flow through the exhaust side, not expansion. The faster the the exhaust gas flows over the exhaust turbine, the higher the spin rpm of the turbine,and the direct result is that the compressor spins faster, thus more compression happens on the intake side. High engine RPM will cause the exhaust gasses to flow at a faster rate than low engine RPM. as far as cooling goes, turbos in airplanes get hot enough to make the turbo glow, and that is with a significant amount of cold air passing over them.   You can only imagine what kind of stress that this kind of heat puts on the bearings and the oil. In the doghouse of a boat, with no air movement, water seems the most available method of getting the heat out of the turbos.

That looks like a great boat and a rare model at that. It's certainly worthy of a 440. It's the same hull as the Wildcat and many of those came with 318's. I have friends that have one and it ran 45 mph and had plenty of power. They eventually repowered it with a 351 and wish they had stuck with the 318. That's a plenty nice enough boat to stick with an older, original type of engine.

Bill, on that hull that model is very rare. I don't know why they called it a Marauder and not a Wildcat. It's not in the brochures and there is only one in the Diaries. Don't let rare be confused with valuable as outside our circle of very enthusiatic fans, there's not a lot of interest from people looking to buy a Classic boat. Maybe someday, but not now. Aside from it being a Marauder, the color is great and the gel looks like it's in good condition. IMO that is a great Classic boat to have/restore and a 440 would be a great engine for it.

email ReidP and ask him what he thinks of it as he knows that vintage probably better than anyone.
