I have a friend with a 1997 top gun and it only has a 4gal holding tank in the head under the floor he asked if i would check with you, top gun guys to see if you have any thing different and were is it.

That is it. Most if not all Top Guns were set up to use the tank and/or pump overboard. I am looking at a 1992 owners manual that shows this.

Yeah they really weren't built to be express cruisers. The new ones don't have one at all unless you specifically request one during construction. Mine has a portable one that has to be emptied manually. I have never let anyone use mine. It was never used on the 92 model had either. I'll get to a dock if someone needs to go that bad.

My 1993 Has Never Been Used As Well, How Do I Pump It Out If It Dose Get Used?

There is a valve under the seat that makes it as big as you want !

That's the only way! Who wants sht in their boat.

My TG has an enclosed head with electric flush, havent tried it yet. Cant you get it flushed out at the marina? This one is new to me. Any info would be appreciated

There will be NO shting onboard !!!! & only pretty girls may use the head for anything !!!!.....Men will do as god intended us to do !!

no ****!!!!!!!!!!! haha, no pun

I had to replace the one in my 90 TG last winter because the bottom was all rotted out. Thank god it hadn't been used for a long time and there was no smell or mess at all. I called the company that had a tag on it and they must have gone out of business or moved. I had a new one fabricated again out of aluminum the same size for $125.00. None of the plastic ones that I found would work. I think the fresh water tank on the other side is the same size.

waterheater, Yes I think all marines have a vacuum system to empty it. I think they are all the same but mine has 2 buttons the top one will bring in the water through the hull and then flush to the holding tank. There are two valves under the bench seat on that side. The small hose is for that water and if you open the valve with the large hose and push both buttons at the same time it will flush the holding tank through a masserater pump and then out the bottom. I guess that is a no no unless you are so many miles off shore so don't get caught with it left open.

birdog I tried to call you tonight and see how you are doing but no answer. I didn't leave a message.
