leaking RWP

Last time I went out I noticed the RWP had a leak at the shaft area...little drops leaked to the bilge...not much...the leak became weaker to completely stop as the engine got warmer...
So looks like a I need a rebuilt...
Looks like I need to order a couple of bearings and a seal kit!!! ...The bearing itself, you know if its specific or I can have it matched locally If I go with the old one?

Seb,
All bearings have a ISO number on them. Even though a bearing may have the same OD, bore and width, there are several different versions/materials of seals, shields of a combination of both. Go to a power transmission distributor if the auto supply can't cross it exactly by the ISO number. A throw out bearing for a car may get you in trouble!!

Yes, you need a special marine bearing, with special coatings etc. that will cost 10 times what it should cost. My chit bearing has been working since 1993.

Kap, you'll do fine as long as you use quality parts for either the seals or the bearings. What you need to inspect closely is the pump's shaft is not worn or pitted were the seal and bearings ride, if so you can have it repaired or have a new one made.

Honestly, If I were you I'd wait until the dripping is persistant, it's not uncommon for pumps to leak now with the cold water running inside. You could have it completely rebuilt before summer session.
How's the temp gauge?

around 140-160....so it´s not sucking air....

When mine started leaking, it eventually got worse and started slinging water up to the flame arrestor.

I'd just like to restate the importance of getting the correct bearing and not one for another application. With the exception of a partial year of playing carpenter after college, all my work/jobs have involved power transmission components and the engineering that goes with that. Bearings are key to all and I feel I have a good understanding of them. This was my project from mid last week and into the weekend.

4K worth for two taper cups and cones:


Bearings we use are typically not expensive and there isn't a "marine" specific bearing that costs 10 times as much unless you shop for them at a marina. The ISO # is the key.
