Beta 25 Raw water pump


I repowered my 34' sloop 9 years ago with a Beta 25.

I'm very happy with the results, the engine/trans have performed well in all respects.

However this Fall, after winterizing, I realized that the Johnson water pump (207-61500/01) was leaking. 

I removed the pump from the engine and disassembled same. It was obvious that

sea water had gotten past the coolant side seal (see pic attached) and destroyed the bearing . The engine has only

380 hrs of running time. Is there an issue with these pumps/seals that would cause this? I am meticulous with all maintenance, oil/filter changes, etc.

Don't think I should be having this problem with such low hours.  Thank you

Hello Sailorphil,

Sorry to hear that you are having pump problems. While the pump has only 350 hours of run time, it is still a 9 year old pump. Sometimes the calendar trumps the hour meter. New bearings and seals should give many more hours and years of operation.

Thanks for your reply.

Original motor in the boat was a Volvo MD 11C.  It also had a Johnson pump,

which went 15+ yrs and 1000+ hrs before the coolant seal gave it up.

I've already purchased a new pump from you. The shaft was also corroded. 

Regards

Hi Sailorphil,
I had the same issue with the Johnson SW pump on my Beta 30 except half the years and 3 times the hours.
Trouble was that with brg in similar condition to yours the outer race was left behind in the blind housing.
A retired mechanic at my club who enjoys challenges was able to get it out and I rebuilt it with parts from a Johnson dealer and bearing supplier.
I don't know if the hours/age on mine were acceptable; as with most things on boats you could ask 5 different people and 5 different answers.
Still going OK at 1700 hrs.

Hey Andrew,

I own & manage an auto repair shop, have done so for 40+ years,

so I am experienced in mechanical issues (also been boating for 50+ yrs).

IMO 1000 hrs is a reasonable lifespan for a SW pump, 350 hrs is too short.

Wasn't worth the time or effort to rebuild, so I replaced the whole pump.

Betamarinenc was great, had the pump in 2 days.

I did the repower myself, over a cold New York Winter. Love the Beta,

it's smooth, quiet & reliable.  Phil
