Cockpit aft hatch

[Jacks3420]

I have a generator in my aft hatch in the cockpit of the boat. I noticed that the seal around hatch was gone.

I was recently advised and added a weather stripping to the bottom of the latch to make it water tight to protect water from damaging the genset...probably used too thick of weathersealing strip.

So my question can this impede airflow to aft area with generator and cause the genset to overheat after many hours of use. Overheat never happened before this sealing wassuppers. The genset area is only a few cubic feet and has sound shielding on genset.

Also in general should the covers of aft hatch be water tight since it has a bilge in the area? is it only supposed to come with a smaller gasket? How do these hatches come from Parker.

Since I bought this boat 10 years old I dont know how it was originally manufactured any help would be appreciated on how Parker uses gaskets or lack of on cockpit hatches.

also curious to know if I should rebuild helm latch gaskets also.

Thanks,
Jack

What type of generator? I assume that you have a small 2kw Honda generator under the deck? Like the eu2000i.

What type of hatch? Plastic or aluminum?

Regardless, assuming that your Parker is like any other 23, 25 or 28 ft Parker I've ever seen, you have plenty of ventilation into the bilge regardless of the deck hatch seal. But a picture of your aft deck would help to assure this assumption is true.

All of the above ^^^^^^ aside, you should definitely replace a rubber seal on any deck hatch if it is no longer restricting water from entering the bilge. You can buy all sizes of rubber gasket seal through Amazom.

Wow!! That's a big generator. You must have a 34 Parker.

Anyway, yours is cooled with raw water. No concerns with it over-heating.

Ok thanks, yes it is a 34

Look on the bottom of the hatch. The manufacturer and model number should be there.
Then go to the manufacturers web site and match your part number with their stock, and order one.
Should be fairly simple.

Am I using the wrong terminology. This is the flush fiberglass deck hatch in the cockpit not a window hatch.

You might need to contact Parker directly as your 3420 is one of the rare models to include a flush hatch to see what they sourced for gaskets on their in-house manufactured fiberglass hatch (some of the 90's models did include factory flush decks). Most other hatches installed by Parker are Tempress, Innovative Products, etc. that are not the flush model like you have.
