Still cant find the pump!

[tollycraft]

I have a new to me 1988 30ft Weekender. Not getting heat in the cabin. Checked the manual and it states the raw water pump is located under the aft seat dinett table port side. There is no pump there. I believe I just need to bleed the lines at the pump (or at least thats a good place to start) to get the heater working. Anyone have or had this boat that could advise, that would be great.

On the 1986 weekend the a/c compressor was under the forward dinette seat on the port side. Look at the a/c unit and follow the hose back to a through hull. My guess is your cooling water pick up is in the engine room and the pump near by.

Thanks SBW1, your right re: the a/c unit and its location, I will follow the hose as you suggested. Up this weekend and will let you know what happened when I get back. Thanks

Tolly,

On my '89 340 DA my AC unit cools like crazy but won't heat. There is a reversing valve in the system that gets stuck and will not allow the system to reverse (reverse cycle). If you can track down that valve and tap on it with a mallet you might be able to break it free. I was not able to do so but it still cools and I am going to worry about the heat part next fall.

I have a 30' Sundancer and the pump and thru hull fitting are underneath the aft cabin. I'm sure yours is different, but tracing the hose back from the A/C unit should lead you to it.
Is the boat out of the water? If so, look for the intake on the bottom.

Thanks everyone, going to look at all the possibilities of why this thing isn't working.

Once you find it, you might need to prime it to get it working. It's easy to do.
Just close the intake valve on the thru hull fitting.
This fitting is probably located very close to the pump.
Depending on the kind of fitting that you have this could be a two step process. The first step is to unlock the valve, and the second step is to turn the valve off.
Disconnect the hose from the valve.
Point a garden hose into the hose you just disconnected (the side befor the pump).
Turn on water supply to garden hose, and turn on A/C unit.
Have a helper tell you when water starts to discharge through the side of the boat (mine is on the port side forward).
Put the hose back on the thru hull intake fitting.
Tighten it all up, open the valve, and you should be in business.
Before you start the priming process you should clean out the filter basket at the intake, and replace the rubber O-Ring at the top. Mine has two butterfly nuts that hold the cap down on the strainer.
It all sounds complicated, but if you have a helper on the dock to turn the garden hose off and on for you and to tell you when you start to get water discharging through the side, it shouldn't take more than a few minutes.

An easier way to do this is to turn the cooling water, through hull. pickup "off" and disconnect the hose on the back end of the pump. Then "open" the through hull until water comes out of the pump. Turn off the through hull and reconnect the hose and you are primed and ready to go. For boats with gennys, you just need to turn on the a/c while under way and the pumps tend to be self priming.

Thanks again guys, your help is much appreciated. If this works I'm just going to go fishing this weekend and have a couple soadees when I get back dockside. Going to follow some of my own advise and just enjoy the boat for a couple of weekends. By the way sbw1, you were right on re: WOT on the boat, I hit WOT at 4300 rpms which is close enough and she ran 28mph at 3100 rpms which is where she sounded the best. This is right in the range I had hoped for. She also trolls down as low as 1.5 mph which is slower than I expected as the slowest I would go would be 1.8 mph earlly in the season which up here is now. Seems she is propped perfect for what I want to do. Incidently, I was 28 mph at 3100 with the tanks a little over half full which tells me I should be no less than 25 mph at that rpm with full tanks and I'm very pleased with that. I also go tabs full down to start and she gets up on plane very quickly then I adjust tabs. Very, very happy with the boat.
