  1. Excellent Upgrade 5 Star Review

    Posted by on 13th Dec 2017

    The upgraded pump is awesome. Quieter is better.

  2. Perfect!! 5 Star Review

    Posted by on 16th Apr 2017

    Unbelievable and easy to install. Directions were perfect. Our head used to be so loud now we can barely hear the thing. Wow!

  3. Best Upgrade Ever! 5 Star Review

    Posted by on 4th Aug 2016

    The old pump did click all the time when the vacuflush was running. The new whisper motor truly is quiet and can barley hear it run when you sit right next to it. Huge improvement and worth the money. The bellow also fixed out issue of the vaccum not building up for suction.

  4. one less annoyance 5 Star Review

    Posted by on 27th Aug 2015

    Great product... Not difficult installation.. The vacu-flush head should have come this way to begin with - a huge improvement in the noise level which is especially appreciated at night.

  5. don't think twice about getting one! 5 Star Review

    Posted by on 29th May 2015

    Easy install. Great directions. Really surprising how quite it is. I can not hear it at all. Now I will never know if it isn't working. Great service from you guys - got the pump quick.
    Perfect everything. Wow..really can not hear anything. Great replacement that actually works as advertised.

  6. super easy to change out 5 Star Review

    Posted by on 23rd May 2015

    I bought this unit to replace a 504729 MO27RM motor for a 2000 searay 290. The job took a whopping 5 mintes and i did not even need to replace the guts of the pump, just the motor. super easy and worked great.

  7. An easy fix 5 Star Review

    Posted by on 6th Nov 2014

    A complete kit that is easy to install and improves performance of the pump. Shipping was lightning fast. Thanks

  8. Exact fit ! 5 Star Review

    Posted by on 18th Sep 2014

    Fit my pump perfectly !

  9. Exactly what I needed. 5 Star Review

    Posted by on 30th Sep 2013

    My old head pump was noisy before it stopped working complete. The retrofit kit had everything I needed to change the motor, bellows, gaskets etc. Once I got the entire pump assembly out of the boat (as with most everything on a Sea Ray it was hard to get at) the conversion was very simple. The new setup works great and is very quite.

  10. Whisper Quiet Motor....can't be heard 4 Star Review

    Posted by on 27th Jul 2013

    It's true...the motor noise is undetectable under the loud suction noise of the pump generating the vacuum. Honestly, what is the point of a quiet motor with the ever present, repetitive, and quite loud noise the pump bellows makes?

    My take is don’t buy this kit for the quiet motor; buy it because you need to rebuild at a good price. The kit also upgrades the pivot bolt, the motor/pump connection, and the bolt. The kit eliminates parts and generates suction faster.

  11. Whisper quiet is correct 5 Star Review

    Posted by on 23rd May 2013

    The pump on my head system went out , on the recommendation of my mechanic I orderd the whisper quiet kit , very easy to install a direct replacement fit for my stock searay unit , as it Is advertised this unit is extremely quiet , I no longer here the pimp running from the head room as before , would recommend this upgrade

  12. Whisper motor is less noisy 4 Star Review

    Posted by on 20th Feb 2013

    The motor is less noisy than the original. Would like more detailed explanation in the instructions such as the alignment of the half rings and the small "o" ring. I had to do the install 2 times to get the unit to hold vacuum.

  13. Works as advertised - quieter and faster 5 Star Review

    Posted by on 26th Jan 2013

    A huge improvement over the stock setup.

  14. GREAT 5 Star Review

  15. nice retro fit 4 Star Review

    Posted by on 13th Sep 2012

    After a very helpful discussion with George, the online consultant, ordered this replacement motor. Easily installed by 2 neophytes in boating....and works quietly. Motor mount screws not the easiest to put in....maybe can be put in thru the front. Thank you George!

  16. Great Product at a Great Price 5 Star Review

    Posted by on 4th Sep 2012

    Easy install, great product, great price. Super quiet compared to original equipment.

  17. Major Improvement 5 Star Review

    Posted by on 21st Aug 2012

    It was easy to assemble. Could not believe how quiet and fast the unit is.

  18. Bought this upgrade kit and it really worked! 5 Star Review

    Posted by on 5th Jul 2012

    I have a 1999 Hunter and the Vacuflush head quit working.
    Sealand sells a retro fit upgrade kit to bring my old vacuum pump into the modern age.
    The kit, the instructions were a perfect fit, and all went like t should have.
    If you have an older Sealand Vacumum flush head in need of a new motor, get this retro upgrade kit, it works.

    We bought our Kit from Seacoast services with a dead line and they shipped same day ordered and we got the kit in days, it was great Thanks Seacoast. Job well done!
