170 thru hull fitting for bilge pump

[jdupree]

I have just purchased a 1988 170 osprey.  It has a bilge pump under the deck and the discharge is on the starboard side up high near the stern.  The thru hull fitting needs to be replaced.  I have looked at it and I can't figure out how to access it.  Can it be accessed?  Thanks,

My discharge is located in the same place as yours. Mine has a screw cap (I think thats what you call it) right over that fitting.

Mr. Osprey,

Thanks for the quick response.  I think the piece you are talking about is broken off.  It still will discharge but the piece that snugs up against the hull is off.  Is this the only way to access it?

I think we are a little mixed up. In the picture below of my transom, you can see the "screw cap" that I was refering to to access the discharge tube on the starboard side of the boat (left in picture titled 75 Merc on transom). Through this opening I can access the thru hull fitting.


In another picture in my gallery (titled starboard) you can see the thru hull hole in the high end of the starboard side near the end of the stern.


As for the screw cap, I mean the cap that covers the access hole on the inside of the boat. The small white cover on the outside of the hull is what covers the thru hull fitting.

Mr. Osprey,

I looked at your pic and see exactly what you are talking about.  You have the round access panel.  My hull is a 1988 and I don't have that access panel like you have.  I can see how you can access your thru hull connection.  If anyone reading this or if you have another suggestion please let me know.  If my hose ever came loose from the thru hull connection I would not know how to even access it.  Thanks again.

Sounds like a good place to put in an access port.  With a little sabre saw work and some screws you could have perfect access to it.

i had to do the same with a jig saw to gain access on my 222, the olny other way was to remove the cap...cut it out and be carefull, good luck

I think "deck plate" is the catalog term for the access port.  It's not unusual to have to add a couple when working on older boats.

On mine, I access the hose and thru hull fitting by removing the stern louvers. I can reach down and fiddle with it. Not sure if that applies to jdupree or not. Mine is located port side. If your's is like Mr Osprey then disregard this.

I can't figure out how to replace my fuel overflow vent.

If you use a die grinder, the "rib" that conceals the hoses can be "trimmed" back under the gunwale which hides it from view but gives you some degree of access.  Check measurements to make sure, but this was done on mine.

Yeah, I was afraid of that. At the end of last season I had to remove the screens of the vent as they were so badly corroded. I know I don't want to leave it that way.

Seems AS, in a number of instances, neglected provisions for accessing hoses & fittings.  Hoses, especially, are considered "consumables".  Don't be shy about installing deck plates where they are needed to gain access to critical areas.
