A buddy told me I dont need to run a water pump in my Sanger v-drive as long as I dont idle for to long. He says that the water pickups will push water through the engine when I am moving.Sounds kinda iffy to me. Can this work?

If it's a river / lake boat I'd advise a water pump. There will undoubtedly be times when you have no choice but to idle for fairly long periods (marina's etc). It can certainly be done without if it's strictly gonna be running at speed with no idle time to speak of. It also depends on the boat, engine combo, some run hotter than others, just because.

I think I might try it with no pump( it's about the money), and see how well it works.Since it's a v-drive with no ability to shift in and out while running, I don't know how often I will be idling, I'll just shut it off. Will it pick up water while at low speed, like in a no-wake zone?

From past experience and good advise from REX run a pump. Only race boats use none and that sometimes doesn't work as planed either. Why waste you motor and money because someone else says you can. Cooling is a very important part of a good performing engine. Run a pump

No way! Do like Rex and SS advised; use a pump!

When I was racing my cracker box we ran with no pump and by the time the race was over and we got back to the ramp the water was usually boiling. It worked ok for a race boat, but I would not advise it for a lake boat. You will end up paying way more for repairs, blown head gaskets and re surfacing heads than the water pump set up would have cost.
Get the water pump, look in the REX Marine catalogue.

pump

run the pump.a used one is maybe $75.i think buying a pump is worth more than the investment you will have in your motor.my pickup came loose from my plates and the motor got hot before i noticed that it was off.that was less than a 1/4 mile from the ramp.warmed the motor up at the dock first.if you warm up your motor at the dock you will be over heating before you take off.listen to everybody and buy a pump.

Yes .....


(Sorry guys, I thought this was a yes/no question)

Seriously ....

Here's my old D'Cucci running at NJBA years ago. Notice no water coming out the water exits at the start. I ran it like that for a couple of years. When I went to Aluminum heads I put a water pump on it.
