I noticed guys using a very cool looking bilge type pump for pumping water from a bucket outside the boat to the engine for warming up purposes at the world finals races this year. I would like to know what kind of pump that is and where to buy one. thanks

BadBug, I bought the largest bilge pump that they had on the shelf at Walmart lol, run a clear hose from it to a ball valve so i could control the amount of flow, or shut it off if needed, and used an -AN fitting the same size as the inlet on my boat. Just take the hose loose from the bulkhead, screw on the clear hose hand tight, and with extended leads and alligator clamps, I simply connect it directly to my battery. motor always gets plenty of water, and i just put the bucket that it is pulling from under the exit dump so it circulates hot water until the motor comes up to temp.....cheap but works great.

That seems awful pricy for something that a standard bilge will do. with a 5/8" hose on the largest bilge at WM or the equivelant from the local marine shop, i put out enough pressure not only to run the motor, but water was going through the bypass, so I know it'll work. Thats why i put a cheap ball valve in line so that I could regulate the flow a little bit if needed.

that pump is way too expensive. i've got a 1500 gph bilge pump i use, but an 1100 gph rule would work just fine. in addition to what ego said, i have a bulkhead outlet fitting, and hook a return hose back to the bucket. i use a 5 gallon bucket, but also use a 15 gallon plastic tub if it's real hot/humid, like texas in august. with hi-heat/humidity, the water just gets too hot too fast with 4-5 gallons, before if feel the engine is evenly warmed. and back there, you can feel the bucket 3 hours later and it's still hot :). if you get the water up to 180-200* all the time, you might want to carry a spare bilge pump, 'cuz they don't like to keep pumping water that hot :).

I usually run mine on what water is in the block. Disconnect the pump with the jet-a-way. If it's hot outside the oil is still hot enough.

When I didnt have a jet away i ran mine on a bilge pump and bucket. i had a valve inside the boat and ran the water backward into the pump. The engine ran on what water was in it.

But anyway a regular bilge pump works fine. Catch the water coming out in the bucket.

Caution....

The boats you saw at the Finals, were they jets, or v drives?.... We too warm up the PS circle boat with a bucket and a pump to circulate the water, (in the bottom ram tube, and out the top) but we reclaim the water and recirculate it until warm, NOT too HOT to keep your hand in..... The "soak" time for the cast iron warm up is enough, (and we do not run water through the oil cooler and 50 wt oil during this warm up)... The CAUTION part comes when you launch the boat into COLD river/lake water and ram it through "too HOT" iron engine parts in large quantities, under high pressure, like from a jet pump.... The v drive uses "ram" cooling, so relative low speeds don't push too much cold water, too soon.... Sadly, this lesson is usually learned after the heads are cracked as the water will drain down to the block inlets, leaving the heads HOT and DRY, just waiting for that cold water to mess them up.....
