are ready to run. By that I mean alternator,rad, ect.
Thanks ED

I'll let you know what it weighs when it comes out. I also have a
couple of Ruggerini/Deutz 20 hp air-cooled diesels that some guys want
to know the weight of. I'll weigh them next week when I get a day off.

engine for a project???

The Geo engine is not really planned for any particular project. The
'94 car was bought very inexpensively and is in great shape. I'm going
to be temporarily removing the engine just to satisfy my curiosity of
its usefulness in other projects. I like to size things up before I
start my first hovercraft build.

For sure ... no. Raven Redrive lists weiaghts of their various
engine/redrive combinations. However, they only list dry weights w/o
radiator. They also probably run headers w/o a muffler. With those
qualifications, their G10 with redrive is 118lbs and they claim the
redrive portion is only 15lbs.
So around 100lbs, and then add on muffler, oil, radiator, and coolant.
I would guess the running weight to be around 150lbs.
BTW: I'm on the same path. I have my junker Geo with fuel injection and
will be building the power train this summer and maybe spin a few
props. I recommend getting the Raven Redrive manual for engine
selection and modification. It covers everything from car selection,
removal of components, to modification for ultralight use.

dry. Add radiator, exhaust, hoses, and water and I assume it's around 100 lbs
or maybe a bit more. That includes the alternator since you really can't run
without it. It's inseparable from the ignition coil.
Barry Palmer
installed on the Sevtec Geoduck weighed 164lb wet and running, with the
cast iron exhaust manifold, starter, alternator, short pipe and
muffler, manual shift flywheel, radiator (mounted beneath the lift fan)
and air cleaner. Maximum power was estimated at around 45 at 4200 rpm,
as determined by propeller load governing maximum rpm.
Yes, one could throw lots of money at the $500 wrecker engine, and
decrease its reliability by turbocharging and replacing the cast iron
manifold and matching the engine to the propeller to run at higher
rpms, and by shaving the flywheel, and maybe even more, but it is
hardly worth it (unless you are trying to fit an existing aircraft that
is set up for a too light weight engine.)
The engine is a rather awkward package unless one installs it near hull
bottom level, which Sevtec could not do as an attempt is being made to
comply with USCG regulations (without marinzing engine components) with
this non-marine powerplant, as is the case with all Sevtec designs.

A few questions I'm sure a whole lot of readers are interested in:
- Are you using all-stock parts?
- Did you turn down the flywheel to reduce weight?
- Stock radiator?
- Separate coolant reservoir?
Thanks.

What is the USCG regulations concerning the location of the engine?
Thanks,

stock. There are a bunch of lightening measures besides what you
listed Ken. First is the selection of the right year. 92,93 and early
94. (earlier and later can have weight issues) Then swapping out the
alternator and starter for earlier models. finally, trimming off unused
flanges. All outlined in the Raven Redrive manual.
As for lowering the center of gravity, you could also run a dry sump
(basically get rid of the oil pan on the bottom) and have a separate oil
reservoir.
