Throwback Thursday: OP-4 vs. OP-6 Impeller Pump

Tiffany T. - Thursday, June 05, 2014
Reverso OP-4 and OP-6 impeller pump

Throwback Thursday has us time traveling. The oil change pump OP-4 (left) was replaced by the updated version OP-6 (right) several years back. The redesign featured more streamlined, improved switchguard and breaker on the end of the motor. The pump maintained the same convenient internal and external threaded ports and quick flow rate of 3 gallons per minute. As Reverso's best-selling oil change pump in the marine industry, we still receive calls to this day from boat owners that continue using their OP-4 to maintain their engine oil. Here are common questions we get asked:

Are there spare parts available for the OP-4?
Today's impellers (360010 and 360014) are compatible, however the new cover gasket does not fit to OP-4. The cover gasket is no longer available for the OP-4.

I'd rather not buy a new pump. What can I do since the motor on the OP-4 still works fine?
Reverso offers the OP-6 pump head assembly as a replacement part and can retrofit to the OP-4 motor. The simple procedure only involves 2 screws for replacement. The updated pump head will then allow you to purchase the repair kits and rebuild kits currently sold.

Watch Reverso's YouTube video for detailed spare part replacements.

Customer question regarding OP-6

- Thursday, February 10, 2011
Q: I have purchased OP-6 12V oil change pump for my Perkins 4-107. Do I have to install a shut off valve between the hose from my oil pan to the OP-6 pump? The OP-6 pump is mounted on the forward bulkhead just in front of the engne. The OP-6 is level with the top of the enigine. My concern is bleed pass the impeller.

A: For the integrity of the oil system it is always wise to install a shut-off valve at the oil pan of the equipment. This insures that in the event of a failure in the hose or oil pump that the engine does not loose oil and fail.

Also, the pump would work better if you can mount it a little lower on the bulkhead. Your impeller will not have to work as hard to lift the oil and priming will be quicker.

Customer question regarding cross-contamination

- Monday, November 08, 2010
Question - "I have just purchased a new boat and have requested to install a REVERSO pump system for the main engine, generator and transmission. The boat builder representative is telling me he can only install it for the engine and the generator, the reason being given to me is the possibility of engine oil and transmission oil contamination. I am a bit skeptical on his contamination concern. Could you help me on that issue please?"

Answer - Your representative could be right. On some of the newer vessels the transmission requires a more refined oil than that of the engine or generator. With our GP-3013, a 3 valve oil change system, there is the possibility of cross-contamination. If your transmission requires the more refined oil, and it is contaminated with engine oil, it could cause damage to the transmission. Typically, we have seen these new transmissions on the new, high performance vessels.

We would suggest that you confirm the oil requirements of your transmission. If it requires, for example, a 30W, like the engine, then you should have no problem using a 3-valve system with no worry of cross-contamination.   If you find that you need a different oil for the transmission, you can use our GP-3012, a 2-valve oil change system, for your engine and generator.  Then use our GP-311 or OP-6, reversible pump, solely for the transmission.
