Running Your Boat With No Impeller And No Water Intake

[wakeboarder3780]

Running a engine dry can be done but your water temp gauge is not even close to accurate dry. The engine will have hot spots. We ran engines without water circulating in drag racing. We ether filed them with water and caped them off or filed the water jackets with other things epoxy. Now days they just don't put water jackets in the blocks and heads they are billet.

The reason to change oil well hot or warm, the sediment is suspended in the oil and comes out with the oil. when you leave it for long time it settles and clings to the pan.

Out some old used oil in a jar and leave it. Then dump it out and see what you have left.

That was my understanding as well. Hence me wanting to run it.

Bill, the saving money comment I made was in reference to them having to buy a tool (vac, warmer). I was just saying that I know them well enough that they wouldn't want to buy a tool. The people I'm helping are *very* careful about money spending. I'm not saying the impeller deal "saves" them money directly, it just prevents them from having to buy a tool is all.

All said and done guys, I agree with you, if it were my boat I'd drain it cold and that's what I'll suggest. If they don't want to do that, it comes down to installing the impeller and running legitimately for a while. Either way it's fine, just mainly wanted to have a discussion about anything else that could go wrong.
