Thanks for sharing- that sounds like a great option!

Moving your thread to the appropriate (2.5L) forum.

That's going to depend on how warm the engine is, how cold the water is, and whether or not the thermostats are open. Telltale "temperature" is not an indicator for cooling system health on 3L...

They should fit right onto your cowling... but don't go try to fish a tournament with a 450r decal on your engine.....

For future reference- please be sure to provide the Required Info when...

No- they use setback brackets that are designed with their jackplate, and they do not mount to the Engine Mounting Fasteners. Very different from "spacers".

Used to see it a lot until we added re-torquing the fuel rail retaining nuts to the "Annual Maintenance List". That seems to have made a very significant decrease in the number we see.

Troll Control is limited in how high or low it can adjust throttle. Biggest thing is not to push so much water that it's overcoming the cooling water supply at that specific speed. Most commonly...

Stack the washer on the INSIDE of the plate (NOT on the engine side). Use only the hardened washer provided in the bolt kit for that location.

Running pushing water really hard generates a considerable amount of heat. Respectfully, this engine wasn't designed as a trolling motor or to be idling around for hours while graphing. We know...

Meant to comment on this statement: Mercury/Quicksilver filters have shown up in three different color configurations over the last 2 calendar years: Red, Burgandy, and a brownish-burgandy. All...

Now Joe... you know somebody probably found some more of those concrete spacers when the supply problems hit early 2018... but it SHOULD have that new style wax-coated gasket. Fingers crossed for...

Moving to the Fourstroke Forum- please be sure to provide your serial number.

Idle SPEED seem normal? What maintenance have you had done?

And inspect the plugs for any that have obviously different color or burn pattern, metallic fragments, or cracks in the porcelain.

You'll want a 10' extension harness so you can leave the connector in the aft end of the boat (NOT in the rigging tube).

I'd go with the 14 pin harness for extension,.... easier to obtain as it's...

AND be sure the vertical air inlet fitting (brass) is TIGHT. There are a few out there that were loose right out of the box.

Comparing 225 ProXS and 250 ProXS Optimax they should both have the...

+3 on alarm bells. The one I'm rebuilding got a brand-hammer-new block.

^^^^ :thumb up2:

Before you get too deep into connections and NMEA-2000, I'd suggest looking into a video you can post on the "tube" so we can see exactly when you turn the key on, and what is occurring.

If you...

Nothing that would permit the engine to run AT ALL with fuel pressure that far below air pressure.

Quite possible. There's one company in particular that was known for doing that kind of stuff under previous management.

Isn't anyone going to suggest tightening the NUT behind the wheel? All kidding aside, the key only provides general location of the wheel to the shaft. It's the NUT that provides the clamp load...

Next thing I'd recommend is to visit the Mercury 2.5L Forum and ask this question as the telltale comes FROM the thermostats, meaning there may be little (or no) telltale until, or unless the...

But there's rocks-a-plenty in most all of them.

Yes that is what you would do, and as far as the dealer, it depends on what you're contracting with them TO do. If you want that done and pay an agreed amount then yes, it could/should be part of...

+1... switch gauges and try again.

Record pressures:
-At idle
-Under Acceleration
-5/10/15 seconds after shutdown (restart for each time period).

Times beyond 15 seconds are only very...
