Great subject. Depends on which engine and outdrive of course, and you have opened a subject that will be "actively" discussed and debated. You will get lots of advice on what others think you "need to use". But mainly I say use the best quality oil that meets the requirements for your motor and change it regularly. There is a great site just for oils run by guys who really know their stuff, called bobistheoilguy.com. I valued their opinion pretty heavily.

I am happy with using Redline synthetics in my cars and will use a synth in my boat too. I am going to switch over to Torco in the boat since it has some additives that help my older engine design.

For drive oil (I have an ancient drive with a clutch dog), I am going with the Redline Shockproof Gear Oil. But your choice should be based on your needs since several drives call out for specific spec oils. I did all kinds of searches and then talked to the engineers at Redline, Torco, and several others before I made my choices.

Lastly, if you end up ordering some specialty oil, make sure you can get it from a local source or order it by the case so you aren't waiting for UPS truck when you need an unexpected oil change.

Good luck on your quest :)

I think you should get some of those Johnny Cash "ring 'o fire" spark plugs. I hear they'll make you so fast you'll get thrown into Folsom prison.

What you do is drill and tap a hole in the engine block just above the oil pan. Put a spark plug in there. Now splice together two plug leads from one of the regular spark plugs (don't worry, there's plenty of juice to fire two plugs). Connect the extra lead to the block spark plug which will now burn off any gas that gets into the crankcase and will prevent oil dilution.:yes:

Or, if you think you can handle the extra speed drill and tap for 8 plugs, just below the bottom of the stroke for each piston. Wire them in so they fire on the upstroke of the piston (look at a firing order for your engine - you should be able to figure it out) and they'll DOUBLE YOUR POWER!!!

Of course, before you do this you'd better install external steering. :yes:

You won't find this in any of the hot-rodding books because the pros don't want to let all their secrets out. Just by telling you this, I'm sure the black helicopters are being readied to take me out, just as soon as their tech guys trace my IP address. That's why I've got so much travel scheduled lately.

Don't forget you can drill holes in the bottom of a traditional deep-v and get the aeration and speed of a stepped hull. The larger the holes the better. It has been shown they are most effective when drilled underway. Deeper water works best.

Spark plugs in the oil pan...REALLY

but instead of water or alcohol use a 55% solution of nitro glycerin

Pull your motor, lift the hull off the trailer in the air, check the entire bottom for imperfections, drop it down on dollies and remove the windshield, flip her over, grind and fix all of the bottom imperfections, sharpen the running edges, and pay attention to the transom area in particular for a hook.

Next, install solid motor mounts or design a cradle if you plan on something beyond 500 horses and want the hull to stay glued together. Then, in the bilge, install a sandwich layer of glass weave, some coring, and another sandwich layer of glass, and then finish with gel as a primer for a bilge coat. Make sure all of this glues the stringers down. In the process, check the integrity of the transom and make sure there are no voids.

Run a twin ram steering system of your choice all the way to the helm. Assist don’t get it done. Measure for the rams and get them mounted inside of the tabs, so your pivot points are shorter and provide a more solid support system. Go with an external steering reservoir, so you can actually monitor the fluid level. Back up your rams, tabs, and any other outside mounted hardware that comes through the transom with stainless plates, all of it, no short cuts.

Buy and install decent headers. Forget about diverters, as you will have reversion issues sooner or later. No, you won’t see miracle enhancements in your numbers, but that engine has got to breath. And the weight reduction should make the boat fly and land flatter with more predictability.

Install power that will get you home. Error on the side of being conservative. Low compression, big cubes, and normally aspirated will help you finish at the typical rally. A drag racer engine builder does not necessarily make a marine engine builder. Also, the “fastest” boat at the docks isn’t always the fastest boat on the water, because of what I just said in the previous sentence.

Get your tabs out of the water. Yes, some need them, but when they are in the water, they are scrubbing speed. Enough said.

A raised x-dim is your friend. I like the XR upper tied to an IMCO XR 2-inch shorty, but some don’t. A heavy duty transom assembly keeps things from moving around a lot less. Replace the flywheel when the engine is out, as it is a cheap part. Borrow and try props until you can’t stand it anymore. Repeat. Then, buy some. Get to know and trust your prop tuner and let them check your good stuff out on every off season. I like Juile and Matt at Throttle-Up.

Buy a trailer that suits your needs.

Take it to the water, take it slow, wear a good life vest, stay sober, and push it when you are comfortable with what the boat does, and you know what it will do next instinctively. Dress her up and take it to a rally. Enjoy. Repeat.

Wouldn't change a thing. At least for now. Oh, and I like Rotella or Valvoline Racing, Lucas, NGK, WIX, Latham, Livorsi, Mercury, Hydromotive, Precision, MYCO, and Manning brands. All good.

OK, we've taken a serious turn here. I'm using Quiksilver 25w40, changed 3 times per season (about every 15-20 hours) and Wix filter. I'm still leery of running full synthetic in the 525. Is the 25w40 a good choice?

I'm using the Quicksilver "high performance gear lube", the green stuff. I change it once per season.

I guess I just figure you can't go wrong using the top of the line lubricants from the manufacturer. Any opinions welcome.

Todd, this is my sea strainer set-up. The SS raw water pump is very cool. I don't know why they used a plastic pump on a $40,000 racing engine. http://www.donzi.net/forums/showpost.php?p=566666&postcount=38

Changing oil is all a scam from the oil companies. Heck, my BMW's on-board computer says you don't need to change the oil for 10,000+ miles, even after doing track days. And you wouldn't want to second-guess German Engineers, would you? :smash:

I figure if a twin turbo 6 can go 10, 12K miles between changes, I should be able to get 5 or 6 seasons out of the boat. After all, it holds more oil and I don't cover that many miles with it each year.

As for brand, they're all the same. I heard from an insider source that there's only one refinery located somewhere in the Northwest Province and they just put the same stuff in everybody's different bottles. You should just buy the cheapest stuff you can find instead of paying for all that fancy marketing.

Yup. I change oil & filter & run it on the hose before putting it away for the winter. I change it two other times during the season.

There weren't a lot of options and that hose is so stiff that the fittings have to be in near perfect alignment. That was really the only place I could put it. It's from Teague.

The service manual for the 525 says to change the oil & filter "every 25 hours or 30 days, whichever occurs first" It also calls for the Mercruiser 25w40 so that is what I use.

OK, this is getting way too serious.......:nilly:

Thats Great! As we all know how petroleum oil has improved in the last ten years and will last twice as long in a (gas) engine. I still too hear those same horror storys about NOT CHANGING OIL..

Oil oxidation is still the same... and left in any engine creates a rusty friction that will.. well you know the rest. Have your friend spend his $$ on his TOW usa membership.

On a serious note: Burning candels are essential in your pre trip routine. Sure the things like.. Fuel. Life vests. first aid kits are important.. but nothing makes you feel as good or confident as "burning a candle" before you take off with your pals.

We all know Cats run faster with similar power than V-bottoms, but that would be such an expensive modification, not to mention the potential negative effect on the appearance.

I think Fabio Buzzi was on the right track with the whole wing idea, he just didn't go big enough.

What you need is a wing/radar arch that is large enough to generate the lift necessary to cause your boat to "fly" just above the water, thereby completely eliminating that pesky drag from the water on the hull.

Location of the wing might not be "appearance neutral" because it would have to be located at the fore/aft center of gravity, which might place it in an odd location.

There you go. An easy 15 mph. :yes: .

And think of all the interesting dock conversations your boat will now be the center of.

We all know Cats run faster with similar power

So if I'm reading this right, then we've all been duped! The big OEM power guys have been using GM cores for their motors. But the real race guys, the truly fast, have no trouble blowing past anything with a stock Merc or Volvo (i.e. GM) powerpant.

What are they using? What's their big secret? Why won't they open the hatch?

I'm here to blow the lid off this!

Clearly, they're running Mercury power. Not Merc Marine - no, no, no, as we've already identified, Cats are faster. I believe the big secret is that they're running Mercury Cougar motors!

That's why Ford had to axe Mercury - the fast boat guys were worried that too many people would put two and two together and as they are a connected lot, they pulled a few strings and called in a few favors in Dearborn and the next thing you know *poof* - no more Mercury, and no more Cougar.

Of course, the Cougar didn't really disappear. The fast guys weren't about to see their secret go-fast source dry up. Under cover of night, during a supposed 'change over' of the facilities, the entire production line quietly moved to an undisclosed location in the far east. There they have imported a select group of former Cougar technicians to build a very limited supply of these ultra-fast motors. They keep them happy and living like kings with unlimited booze and hookers so the secret doesn't leak out.

But it's out now, all do to JustsayN2O's little slip of the tongue. If I were you, I'd be watching my back man! You've just made some powerful enemies!

The idea was to build a 3,000 HP fighter engine that was no wider than a pilots butt!
The project ran out of time and Curtiss Wright's heart wasn't in it, but it's a fascinating engine!:nilly::yes:
It's a 42 cylinder radial that consists of 7 rows of six cylinders each. Each bank had a single head w/an over head cam and two valves per cylinder. I seem to remember the most it did was about 2,400 HP @ about 3,300 RPM.
The sucker has a tiny cross section but it's about 8' long w/the blower and all the coolers.
But maybe this still could be the answer!
