How to install a fuel flow meter in a mercruiser 4.3L 190hp
 

Hi,

I have a fuel flow meter NAVMAN F2100 that i want to install in my
boat. The engine is a MERCUISER 4.3L (no EFI). The boat an RINKER
captiva 192 BR

The manual says that i must install it AFTER a primary fuel filter.
But on the mercruiser after the prinmary fuel filter the fuel lines
are from metal and are very close to the engine.

Any of you boaters got experience with installing this meter on your
boat with a mercruiser engine.

Als tips and photo''s are welcome.

You might install an additional filter in the fuel line making it the
primary one (I installed a see-through one) to keep crapola out of the
meter, then the meter downstream from that filter.

I would not install it ahead of the main filter as the main filter is also a
water trap. Those little clear filters are not water traps. Does it have
barbed ends or pipe thread? The ideal installation would be to take a
section out of the metal line, flare the remaining line and install it
there. A not as ideal would be to take a section of the metal line out and
use a couple short pieces of rubber double wall marine fuel line and barbs
on the sending unit if it does not have them already. You do not have to
have hard metal line between the fuel filter and the carb but it is safer in
case of an engine fire.

For what it's worth ... I have a water separator, then an in line filter,
then the mechanical fuel pump that includes a filter, and finally ... that
screen filter that's in the carb input.

I'm sure this rinker with a merc has just a spin on filter/water trap.
He needs to put the sending unit after the filter, even if it is a hassle.

Just add another Racor or Sierra filter ahead of the filter and install the
flowmeter between the 2. Will cost an extra $30 at most. Always nice to
have an extra filter / water trap.

Actually no it ain't. This guys got a 19ft runabout with a v6. He don't
need more fuel filters. And you are forgetting the all those extra
connections are just more places to have a leak some time in the future.
Not to mention buying two spin on filters instead if one.

It's a 19' runabout. You don't need no fuel flow meter! Makes less sense
than he don't need more filters.

But obviously he's got one now. And I suppose you could make a case for
being able to select the absolute best cruise speed. Generally I agree,
waste of time to put a flow meter on a v6 runabout. Best cruise is probably
around mid 3k rpm. Plus or minus a little is going to make about 15 minutes
worth of difference in run time for a tank.

Have to disagree.... Boattest.com has the rated best cruise on my 210
Classic at 3500 rpms, 3.8 mpg. After a prop change and addition of a
hydrofoil, actual measurement indicates 3.65 mpg at 3500rpm. My best
cruise is actually 2500 rpms, 4.24 mpg. Thats a savings of 5 gal. per tank.
A flow meter will also give you instant feedback when you change the load.
It will pay for itself in a year or two at most.
