I have a 2008 170 Montauk which I purchased new in July 2008. I launched the boat for the 2009 season on April 18. When I returned to the dock two weeks ago I noticed a small amount of water in the bilge. I checked the bilge plug and it was a little loose so I figured the water leaked in through the loose plug.

Yesteday (April 27) I went for a three hour ride. I remembered the water in the bilge from the last ride so this time I made sure the plug was tight. When I returned to the dock I noticed water in the bilge again (about 1 inch). I keep the boat in a "boatel" so I had the lift operator put the boat on a wash rack. I immediately noticed water dripping from the through hull fitting even though I had not yet pulled the bilge plug. Looking up at the through hull fitting from the bottom I could see that the water was dripping from around the fitting rather than through the drain hole. I pulled the plug and drained the water. At that time the water stopped dripping from around the fitting so I don't think the hull itself is holding water. I took video and pictures of the leaking fitting and can post to photobucket.

I plan to take to the boat to the Whaler dealer for repair. Here is my question, when the factory drills the hole, is the hole sealed/fiberglassed before installing the through hole fitting? My concern is that some water has leaked/saturated the foam core.

I found this info in the owner's manual:

NOTICE
• Depending on the type of boat you have, you may have underwater fittings. Any fitting that will be
underwater needs to be plugged or the seacock needs to be closed.
• Through hull fittings should be checked for proper seal annually. When the boat is in the water the
underwater fittings can be checked for dripping. It is recommended that the underwater fittings
be removed, cleaned and resealed every other year.
• If the through hull fittings need to be replaced, it is recommended that an authorized Boston
Whaler ® dealer perform this type of repair. Through hull fittings that are improperly installed can
cause premature hull failure and may void the Boston Whaler® limited warranty.

It almost seems like the fittings are expected to leak? <sigh> Certainly the foam has to be sealed off? Should the warranty cover this repair? I'm glad I don't keep my boat in the water.

Why did Whaler decide to go with plastic fittings? Why did they install the fitting through hull to the bottom rather than through hull to the stern? I never had a problem with my 79 15 sport!

Fortunately time in the water compared to out and age of your boat is all in your favour and little or no chance of water ingress to be of concern

It only says "It is recommended that the underwater fittings be removed, cleaned and resealed every other year." which is just as well with over 10 fittings on my 210 it would be a considerable cost otherwise.

Through the transom or hull is same same as far as I can see, and less pipe routing in your case, plastic or bronze won't make any difference to poor workmanship in sealing.

A good dealer should check it and just fix it for you

I was thinking at speed the water is pushing on that fitting under pressure...more stress. Through the transom that area is "dry" when on a plane. I guess it doesn't make a difference.

The fishbox drains on my 210 through the hull, pluged from inside the boat and have small shields (shaped like a dished arrow head) on the outside, but this is to assist self draining when moving.

You are right these would help in stopping water ingress in part, at speed, should there be a bad seal, but this would just be prolonging the fault.

I wonder why they are not fitted to your MT170 ? Maybe you can ask your dealer

Update: The through hull fitting was resealed by dealer under warranty.

Great news, no doubt you will keep an eye on it for a while yet :)

Did the dealer remove the thru hull fitting and replace it with a new one or just add some sealant around the existing fitting? Just adding sealant won't last long if at all. The fitting needs to be bedded in sealant.

I don't think the actual fitting was replaced, rather it was removed and then resealed. No, they didn't just add sealant around the existing fitting.
