running the Engines on the "hard"

I have never had to try to start my engines while blocked up on the hard - my boats in the past have always been in the water first. How do I connect a water hose t o the raw water intake side of things so I can turn them over and not ruin an impeller in the process?

My strainers have flush connectors where I can hook up a garden hose and supply the engine with water.
If you have strainers, you could make an adapter to fit the strainer lids and hook up the same way...kind of a hassel though. Just remember that you will need uninterupted water flow to each engine you're running and if under pressure,, such as from a garden hose, shouldn't have too much worry about your connection being air tight. Only when you're drawing water via raw pump, you need to be sure there are no air leaks ...

watch your temp gage as the flow might not be enuff to rev over idle speed. Also do not assume someone won't turn off your spigot/hose.

You need to find what they call a "fake a lake" it looks like a toilet plunger with a garden hose fitting. Just put the plunger end over the water intake against the hull. the stick part adjusts to hold it there. and turn on the garden hose. water will spray everywhere thats OK
good Luck

Here's a link to a "fake a lake". Looks like it would work good as long as you had someone to hold in position...........John

If you don't have strainers, remove the intake hose from the through hull, support it in an upright position, insert a garden in it and away you go. Best to do this with two people, one at the helm and one at the hose. Don't flow much water until the engine starts running.

I made and used one of those flushing devices a few years ago, and it worked fine. Put a plastic hose fitting into a toilet plunger, get a handle long enough to hold it up to the intake (consider extension handles in the paint dept.), and it should work fine. Check the configuration of the intake to make sure the plunger fits over it completely, and insert the hose fitting where it will allow the intake to be fully covered. Like an outboard flusher, water will spray out from the fitting. Check to be sure exhaust water is coming out properly, and monitor engine temp.

Thanks! all good suggestions. Wow! $54.00 for the "Fake-a-Lake" which just looks like a modified toilet plunger anyway. Will build my own! Thanks again guys..

I run my 26 on the hard all the time. I plumbed in a hose fitting connected with shutoff and then shutoff the scupper.
Went over and helped a buddy fire up the Mercury 500SC Bulldog he just put in a 25 Daytona Cat. Running hard on the hard!

make sure you lubricate your cutlass bearnings if you plan on spinning the props in or out of gear.
Lubricating the cutlass bearings

What is the recommended lubricant for these bearings?

water

So...do they need a continuous supply of water if you are going to spin them for testing purposes? or just wetting them down would suffice for a period of time?

Short=Wet
Long=Hose
Don't let them get hot.
