Did I misunderstand something on the Paris White for the engine paint color? They look "creamier" than the other white to me: https://www.youtube.com/shorts/bzdAZ7KS548

I believe this is it.
it matches perfectly.

I stumbled on this interesting additive comparison video tonight, thought I would share it
2000 Sea Ray 380 with CAT 3116s. Any idea who's the manufacturer and P/N for the engine raw water intake strainers?
Pretty sure it's Perko either 0493 or 0500 with 2" inlet/outlets. There are zero markings anywhere on any of the parts, other than "IN" and "OUT". The Groco units I've found online don't look the same.

Perko yes, that's all I know though.
Perko P/N 0493009PLB
it turns red if there is enough vacuum in the intake to pull the spring down indicating the filter is clogged.

I replaced mine. I bought from Walker Engineering along with a new set of air filters.

This doesn't look familiar to me, do I have these on my 3126s, and what do they do?
You likely do, they’re near the air filter element in the airsep. Basically a vacuum gauge that clicks into position if the intake vacuum (before the turbo compressor intake) gets too high, indicating the air filter is dirty
the element would have to be super dirty for it to actually go red, I clean our filters annually but the reality is they’re super clean even before cleaning. Not sure exactly a dusty or dirty working environment where we boat

Last season cleaned mine with a kit from auto parts store. Despite a noticable amount of black stuff flushed out, the indicators were in normal zone. If never done before you should consider cleaning your filters. Very easy job.

Performance numbers
Full fuel
Full water, spares & tools
Clean bottom
One adult
STBD WOT = 2780
PORT WOT = 2783
did not use tabs
waste 20%
Data below using CAT fuel burn table
General Propeller first balanced and set these wheels to spec
we've taken them down twice now, approx 3/4" each time so we're down now about as much as we can be.
topped off both fuel tanks before test.
I then ran the incremental differences:
speed in knots vs. fuel burn INCREASE per 100 rpm:
If I look at the speed increases per 100 RPM, forgetting about the jump on plane speed increase, looks like the biggest gain per 100 RPM with the least increase in fuel burn is between 2200 – 2300 RPM.
Sweet spot cruise looks like 2200/2300 RPM

If the boat feels good at 19 or 20 knots then that's your cruise, right?
It looks by your data that anything above 20 knots is additional load on the engine without results. No need to sacrifice engine life. Trim tabs will however increase speed over load somewhat by setting the hull more parallel to water flow, less drag....

Dancer, thank you for the clear information.
What are your prop specs? With 22x24 props I am only getting 2600 wot and 17 kts at 2400 although it seems to vary from 16 to 19 depending on sea and wind conditions
We only got 2750 on sea trial in perfect conditions, empty tanks and geat conditions but there were five people onboard..

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++
At the time of the December 2021 survey, the props were 22" x 24"
I am now 22" x 22.5"
My numbers were achieved with absolutely full water and fuel
I believe I added some significant weight with the removal of the carpet and the installation of the premium vinyl plank flooring - those boxes seemed to be rather heavy as I carried them out to the boat
She also is carrying nearly 200' of all chain rode
this is a 450 DA
Hope this helps.
I calculated mine somewhere in the 200-300# range on our 410.

Checked on the boat today for the first time in 7 or so weeks since winterizing. I noticed this past season I was having to put a little antifreeze in the starboard engine after a couple runs. I noticed some coolant in the bills today, and traced it down to this bolt on this coolant tube. What is this about for, just a drain I'm assuming?
