Hey everyone,
We had the boat, 2001 Glastron GS 249 with a Vovlo Penta 5.7 GS, out for the 2nd time today, and I noticed when the engine was running, it was slinging water from the pulley area. Upon closer inspection, with the engine off, I was able to track down where the water was dripping from.
With the boat on the trailer, it was still dripping from the sea water pump housing (right behind impeller). I took it apart, and the impeller is missing a vane, so that'll be replaced, and I rotated the housing 180 degrees and saw an indentation and that is where I think the water is dripping from (picture with pen pointing to indentation), or in that general area since I put my finger down there and can feel it dripping. Is this a weep hole, or is it just a manufacturing mark in the die they used to make it? What would cause this to leak here? I looked at the exploded diagram from Volvo Penta, and it looks fairly simple Seawater Pump 5.0GLPEFS, 5.7GSPEFS - 7797478 - Volvo Penta It's either the O ring, or the sealing ring, correct? How would I pull the sealing ring out to replace it? Should I replace both the o ring and sealing ring along with the new impeller and have a practically new sealed unit?
Also, is it possible for this to leak constantly with the engine off sitting in the water? Thanks.
