Maitenance check?

Postby lgeller » Mon Feb 05, 2018 12:52 pm

While finalizing the installation of the new engines on PLUSH TOY, my mechanic noticed that the hose feeding cooling water to the port shaft was very close to the waterline - he re-routed about 8" higher to prevent any water from flowing back into the engine. Not sure why the port side was lower, but it may be smart to take a look on your boat - it was an easy fix.

Interesting. Thanks. I will look at it.

Your picture reminded me of a question I have.. how many of you have your bilge pump GLUED vs. SCREWED to the floor in the back of the bilge area behind the engines? Mine were glued and both had broken loose. Our maintenance guy screwed one down.

Mac, ours are glued also. I'm not sure I'd be comfortable screwing them to the the base of the hull.

Screwing down the bilge pump bases is a super big no no. The hull at that point is only about 1/4" thick. I would advise checking for leaks, repair the holes with epoxy if all dry, and gluing the bases down. Reasons for it coming loose in the first place are usually not enough sealant applied and contaminated glue surfaces. The hull and pump base should be abrades with 60 grit sandpaper and than cleaned off before gluing.

Larry,

The height above waterline routing of the hose feeding the shaft seals is not of much concern, as the other end of the hose should terminate at the vented loop which is well above water line.
With this said, there are a few boats where the shaft seal is fed from the hose attached to the aft end of the engine heat exchange which is closer to water line.
