Limited05's mods, question ?
Limited05 made a post about anal mods (I have to call it something).
"knife-edged the ride plate trailing edge"
"smoothed the entry and exit to your pump"
"where is your fire extinguisher located?"
Has anyone else done these ?
Did anyone notice any differenceds moving the fire extinguisher ?
What is knife-edging the ride plate ?
Is there mph that can be found from pump mods.

Yeah, that pretty much sums it up... "anal mods"... LOL
1. "Knife edging" the trailing edge of the ride plate refers to getting the rear edge (where the bottom and back meet) as straight, sharp and as close to a right angle, as possible. you'll notice that this edge currently has a radius and is rather rough. Build this edge up with JB Weld and then work on it with a file and sandpaper. Remember, I did this in conjunction with other "anal mods", so it's hard to put an exact mph gain on this.
2. When I installed the Riva grate and 12/19.5 impeller I noticed several areas within the pump inlet cavity that had black silicone protruding in the path of water. I cleaned it up and smoothed it considerably. Did it yield any gains? I don't know, but I do know it LOOKED like it could hinder flow, so I fixed it. Also, the pump vains had casting marks (flashing) in the fillets and rounds. I used a dremel to blend and smooth them (not grind away, nor sharpen the leading or trailing edge) in hopes of improving flow. Again, the minute benefit is hard to measure in mph... but when you add it to the other minute benefits...
3. Now, as for the fire extinguisher. I don't think for a moment that moving a three pound bottle of chemical is going to be measurable on my GPS. But wait... since it is required, and it fits quite nicely in the rear compartment, why not move it? In effect, it is shifting 6 lbs with respect to the center of gravity. Afterall, what's the first thing we do when Joe Yami pulls up along side at WOT... we shift our weight back and nail it.
OK, so each one is only good for a tenth or less. But add this to multiple .1 mph mods and now you've gained 1 mph... and it was cheap (though a LOT of work). To this day, the biggest bang for the buck was truing the ride plate and grate and filling the holes... 1.4 mph for six bucks!
I'm not saying that these and the other anal mods I've done are for everyone, but they keep me busy, happy, and competitive... and oh, how I love it so!
Good luck on your mods... I'm going to the shop to contemplate more "anal additions".

Never thought I say this but....
Jeff please let me know of all the anal you come across.
I'd be happy to have my RXT follow in your footsteps....

Is the fire extinguisher a possible explosion risk if it heats up.
My bin gets pretty hot.
If it's not I might mount it in the hull.
Then maybe if the engine starts on fire the extinguisher will blow up and instantly put itself out... or maybe not

Yeah, ya see how anal mods can be save ya money... you know what an automatic "Fireboy" system costs for a boat.
That bucket can get pretty warm, but mone has been backthere since February and no problems.

Off topic, but I got stopped by a Game Warden once and he asked to see my fire extiguisher. It took so long to get it out that the Game Warden laughed and said "if your boat catches on fire, just jump and swim."

Hey Franco... I have jumped and swam

I meant "Franko"... sorry!
Jerry, every time I'm under my ski I look at my fiiled ride plate holes and just smile
