Transmission Oil Change

[mistercomputerman]

What do you mean by "uh oh"?

Have you installed stuff not to ABYC standards?

......... 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.

Can't you just put a padlock on the switch?....a chrome one of course!

Sounds like a job for Captain Magneto.

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.

No problemo to change if/when the time comes.

By my count I have three intentional non-conformances that do not affect safety and increase utility in my usage of the vessel.

.....three intentional non-conformances that do not affect safety ......

You should consider a career in politics...!!!!!!!

Funny thing happened when I said almost the exact same thing to the NRC....well it's funny in retrospect.....

NRC - Nuclear Regulator Commission?

NRC - Nuclear Regulator Commission?

Yes, well, Regulatory, the one and only (that I'm aware of).

I'm told it's fine, as long as it's your reactor, but you might need to fix it before selling ifin it don't pass inspection.

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.

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.

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.

Six gallons of oil, yes flipping a switch is the way to go...

Why not just add a sixth zone, connected to a small nearby reservoir, filled w/ the desired fluid, to purge the pump and valve body w/ the desired fluid? The old uncontaminated oil could be used for this purpose.

An alternate option is for the sixth zone to have a loose hose that's stuck into the container of old oil for the purge.

My Custom Reverso Oil Change System has an unused plugged port on the manifold that could be plumbed to a purge circuit.

OR......

......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.....

:smt115
....perform the fluid changing process in a logical sequence....emptying like fluids and refilling like fluids will purge the pump and the refill line and avoid cross-contamination of fluid ''types''.

In all cases, however, if you are sucking in 'new' fluid after sucking out 'old' fluid, you will inevetably re-suck some old fluid with new fluid. You can pour in more new 'fluid' to the unit you are purging and then suck out some more to minimize this effect.

Personally, I don't use the reverso as a sucker. I still prefer to pour all 6.5 gallons in the old fashioned way....through a funnel.

My reverso is the impeller type and reversing that impeller, IMHO, leads to premature failure of the impeller. I don't buy my oil in 5 gallon jugs. I personally find it more convenient to use the gallon jugs.....it's a personal choice......all in conformace with the Amercian Boating Oil Changing Commission.....:grin:
