Here my Thing ...I go out to the sandbar 60% of the time to hang out (10 mi. round trip) i want to in joy some Cruising Time...

[QUOTE=sprink58;3976285]Diego...as Red says...get it running out 3500 RPM, trim it watching the GPS. Where you want to be is just short of where you bring the secondaries in. That the beauty of mechanical secondaries...you control it, not some phantom vacuum signal opening an air valve.

I think you are focused in very well for your rig.[/QUOT

yes I am trying to figure out the most efficient cruise speed , btw John , what do you think about Bimini? that should be fun ...

my sandbar is 1/2 mile round trip hahaha lucky , ask LIL RED he's been there with us. When I want to cruise I just go down to south beach thru the ICW or Ocean depending on conditions.
BTW at 2300 rpm I am doing around 30 mph.

I know it's a lot of expense to do it but I sure would like to see what the GPH on yours and mine (I'm 27 MPH at 2000 RPM!!!) with a Flow Scan would be running like that...got to be getting down near 10~12 GPH.

[QUOTE=Diego9040;3977146]I am almost ready...get my first oil change done, repair some lights, install VHF, etc. and I'll be ready. Maybe in a month~6 weeks.

You, Tom in his Baja, me, who else? JasonMD with the Top Gun might be up for a shake down with his. We really should take some pics of these old Formulas over there and send them to Grant Porter at the factory!!

I can see the caption: "Vintage Formulas Cross the Gulfstream...The Formula Legend Lives..."
