Another New Project That might be of Interest

Just a follow-up to the installation.

It works great, so no more removing the whole pump assembly to access the impeller.

You need to have the space shown ahead of the engine to make this work.

If you try it, good luck:dance:

Joker thanks for re-posting...I have all your pictures saved so when I get ready to go for it.

Have a 3GM30F in our Beneteau 321,just replaced impeller yesterday about a 20 minute
job including replacing both belts

We have had a SpeedSeal for about three or four years, and it has been well worth the money -- quick checks and impeller replacements, and no stuck gasket material to scrape off.

I have not figured out the value of the speed seal other than the knobs instead of the screws. Does it indeed reduce the wear of the impeller? If so, then it might be worth it.

There are two kinds of Speed Seal, the original and Speed Seal Life. The original just has the knobs instead of screws and an o ring (depending on your pump your may not need a gasket just the o ring). With the original you can change an impeller in minutes, this may not be the case if you have a "rear facing pump" like in some of the older Yanmars like my 2 GM 20.

The Speed Seal Life has the knobs, o-ring and a run dry bushing which the face of the impeller rides against. They claim this allows the pump to run dry for up to 10 minutes without damage to the impeller. I installed the Speed Seal Life. I keep my boat on a lift and always have about 45 seconds of run dry before the pump primes. I figured anything that makes the impeller last longer is worth it. The rear facing pump is not conducive to regular checks (boat is used year round so no maintenance season here). Nice well made product.

Thanks for the great explanation!
