One last tip, I see that the anti-vibration bracket shows some rust. I also would not be surprised if the bushing is worn. I suggest that when you replace the pump, get a new bushing in there. You can make one out of heater hose material. Cheap. Make sure there is a snug fit, and you will be rewarded with a little less vibration from the Johnson pump.

The place to start is by putting the 4th bolt in there, of course. Be very careful with that - the pump body is brass and a steel bolt can strip that hole in a heartbeat. I strongly recommend the brass bolts referenced above. I see that one of the bolts is already steel.

While you're there, I'd recommend replacing the gasket under that cover. And given your lack of familiarity with the raw water cooling system, I presume you've never changed the impeller, so while you're changing the gasket, I'd change the impeller too.

If it still leaks after fixing the cover, then I'd recommend replacing the whole pump.

If coming from rear, you need to get whole new pump from skidim
Not so, mine was leaking from the rear seal and skidim has it for $18, that's alot less than a whole new pump and easy to replace. http://www.skidim.com/prodinfo.asp?number=68-5004

Same here on my '96. New seal cured the leak. About a 2-3 beer job.

I had a small leak coming from the rear of my pump, cost of a new pump and shipping to Aust was 5 times more than pulling pump apart, sourcing new bearings and seal, repaint and reinstall, about 3hrs labour plus chasing parts. If you have or now someone with any mechanical knowledge, it is quite easy.

My 2005 PS197 water pump is also dripping from the rear pump area...since a new water pump is $165 vs a rear seal for $18, can someone who has replaced the rear seal provide some insight on exactly how to change it and any special tools required...tks, mac

I've managed to replace the rear seal without taking the pump apart, not easy but possible, you need to be careful not to scratch the shaft this way. The best way would be to push the shaft out so you can get to the seal much easier. If you do that I would replace the bearings as well, you'll get quality bearings cheap, very common size.

The whole unit is usually replaced because at dealer labor rates you are better off getting a new pump than paying the labor to replace the seal.
