Transmission Oil Change

[osd9]

If you look above, you can see where I removed my own post. I was thinking the same 'mixing different oils' thought, but then I re-thought.

The oil change process starts with 'removing' the old oil first....be it 30W or ATF. In either case, the pump/impeler housing along with the discharge/re-fill hose have whatever fluid from the corresponding engine or tranny being filled/re-refilled....30W or ATF. When you go to refill, you are re-filling from the same ciruit which you just finished removing from.

However, and this I just got from the Reverso site:

IMPORTANT NOTICE:
This pump is not designed to pump gasoline or other flammable liquids.​

The motor is NOT ignition protected and could cause a spark and explosion.

Are these even offered as an option on gas boats?

Your welcome Mike. Cheap and effective!

 

[rondds]

Didn't think of that.

Gary loses a green ball.

We have a friend with a 2002 Carver 396, equipped with a oil change system. Not sure of the brand name or if it's spark-proof.

Wow....that's pretty amazing....I mean the friend part....:grin:

Seriously....I would doubt any respectable builder would intentionally install a non ignition protected devices in the ER of a gasoline powered vessel. It may be either a different brand or possibly installed aftermarket by someone who didn't 'look'.

I thought we all decided earlier that ignition protection was not needed in gas boats....

Perfect.

The Custom Reverso Oil Change System I added to my gasoline boat does not appear to be ignition protected.

The Reverso Instruction Manual does not list ignition protection status for every pump, but for all the pumps where it is specified it is listed as not ignition protected.

She's gonna blow...

You should put some sparklers down in your engine room... that would be a really cool mod.

 

[osd9]

Yeah...damn the torpedos.... head off to Pep Boys for your next starter motor....

 

[Four Suns]

a chrome one.

Mike would have no use for a five-point oil change system on his gas boat.
The ZF 63 (I own one) takes transmission fluid- not oil. I don't think pumping ATF into his engines is going to help their longevity...

Well, since each circuit is plumbed seperately I don't think that can happen. In any event I was questioning the 3 valve system Sea Ray installs as original equipment on Diesel boats (Sea Ray doesn't offer the Reverso system on Gas boats). For some reason, Sea Ray installs the 3 valve system on diesel boats up to 44 feet and the 5 valve system on boats larger than 44 feet, hence my comment (only half jokingly) that I should consider trading up...

Last time I checked three components are required for combustion.

So, it's okay to use a hand-held motorized oil-change pump on a gas engine, but not okay to use a bulkhead mounted pump?

Why is that?

My system is fantastic. It drains eight quarts in less than 10 seconds. Plus it pulls from the lowest point in the pan.

Also, when the transmission coolers fail, cold sea water will need to drain from the bottom of the transmission. The best way is to suck it from the drain plug.

So join the elite and dis my stuff.

Here's the Carver on the left. Dom, you met Al at the Labor Day congregation at Curtis Point. He "Nealed" with us that day.

Wingless - don't be so sensitive - they're just busting your hump. Us gas-a-holics are like the humans in Planet of the Apes.

Beware the Gas Boater, for he is the Devil's pawn. Alone among God's primates, he ignites vaporized petrol for sport or lust or greed. Yea, he will murder his brother to possess his brother's land. Let him not breed in great numbers, for he will make a fireball of his boat and yours. Shun him; drive him back into his jungle lair, for he is the harbinger of death.

The Reverso and Groco oil change pumps are displacement pumps designed to pump both ways by reversing the current. Since they have a displacement, they will contain some of whatever they pumped last. That means if you change your transmission fluid then your oil, you will contaminate the oil you pump into your engines, or just the reverse.

The reason some Sea Rays come with 3 gang pumps and only address the main engines and others come with 5 gang pumps and handle the transmissions as well is because the main engines are paired to marine gears (like Twin Disc) that require CF rated SAE oil. Smaller boats have ZF gears that require AFT. The 2 lubricants are not compatible.

Agreed, don't reverse the motor to fill the sump. But, each feed has a shutoff, so w/ only one open at a time w/ the pump draining there is no cross contamination.

Mine is wired to permit reverse, but I only used it once. I didn't like the new oil getting dirty in the drain lines.

There are ignition protected oil change systems. I bought one for Just Ducky over the winter a few years ago when I saw it on sale. Actually, I bought two, one as a gift for a friend. I had to return mine since when I tried to install it in the spring, I found no room under the oil pans for a drain fitting.

Not getting an ignition protected one is probably minimally tolerable since the operator is down in the engine room and should know better than to use an oil change system if gas vapors are present, lest he become a darwin award winner. It's one of those mistakes one only makes once. But it's still not acceptable under the guidelines, which aren't legally binding on the owner. The insurer may have a different opinion.

It's fine by me, but all the information is required to members to arrive at appropriate decisions.

I can understand the ATF issue, but on the 44DB, not sure about the 44DA, the engines and trannys use CH rated SAE oil (30W trans., 15W-40 engines). Is there much more than a trace amount of the old oil left in the circuit? If so, why wouldn't there be a drain to remove old contaminated oil? Really just curious. Do the engines and trannys on the bigger Sea Rays use the same oil? :huh:

So your boat must not be diesel.......pouring 6+ gallons, not quarts, of oil in each engine at oil change time makes a reversible pump more than a little handy, particularly if you buy oil in 5 gal pails.

As you make these "many cool mods" to your boat, you might want to give some thought to what happens when you decide to sell or trade. For example, gas boat with a non-ignition protected oil change pump will never pass a marine survey. When that time comes, you will be faced with either taking a discount to sell the boat or removing the pump and anything else that does not meet USCG or ABYC standards.
