Raw water pumps
 

I've had it with Mercruser's rubber impeller's.

I have changed 4 on the water so far this season.

Has anyone tried the Globe Blue Impeller's?

Are there any other solution's?

Steve

I am. second year, so far so good.

I've had two in the past 7 yrs.

The only reason I had the second is, I started the boat on the hose and the muffs fell off.

They will work for a long time as long as they get water.

Was just wondering are you running strainers?

I am running Sea Strainer's, plus additional low water pick-up's.

HP500EFI's with Whipplecharger's, the stock circulating pump's were removed.

If the motor's take more than about 5 second's to start than the impeller's are in pieces.

Have you ever looked to see if the strainer is full or empty before you start?Could it be draining out when you pull the boat out.Seems to me whenever I do have to pull off my in hose it allways seems to have water in it but I am not running a strainer.Hope you get it .James:cool:

I know I have had no problems with them since switching to the JOBSCO (sp) bronze pump before that it was at least a yearly thing if you get a lot of air the plastic Merc pumps wont hold up.

I did not think that they made a globe blue for a bravo raw water pump. If they do where can i buy one. Last year I asked george for one and he could not get them.

Thanks

do a search on this topic a few board members myself included noticed a oil temp rise with these impellors I tryed them and one failed after 20 hours
You will also need to find the key adaptor as they don not have a flat as the standard Merc ones

Globe Blue Impeller
 

I ordered the Globe Blue Impeller's from Defender's Marine [ Part 2000].

I also ordered the required key's [Mercruser part no.28-56662] a requirement from Globe to adapt to the shaft

I also have been investigating Keith Eikert Single stage units. There are expensive [around $800.00 each] Has anyone tried the KE pump's?
