i just bought a 1964 chris craft super sport with a 210hp chevy/chris craft engine. anyone know how to test run such an engine out of the water? there is a water pick up under the boat, but i dont know if there is any way to supply water artifically. |

Richard,
You should be able to get an adapter from a marine store to put on garden hose.

I would be careful to make sure the engine is running before applying water pressure to the cooling system otherwise you may force water into the cylinders through the exhaust system. Take it easy on how much water pressure you apply. |

how long can you rin one of these engines before it starts overheating/ruining components? |

Depends on wet or dry exhaust, rubber water pump impellers don't last if they are dry. I wouldn't run more than about 30 seconds as you don't know what is in the exhaust line that could be quickly damaged. For example rubber mufflers, steam hose connections. Personally I would arange to disconnect the water inlet from the through hull and connect it with a short length of hose into a dry wall bucket full of water. Run your garden hose into the bucket to make up water being pumped out by the engine. Fill the hose connected to the pump inlet with water so the pump picks up water quickly and gets lubricated quickly then shove the hose into the bucket making sure the pump continues to pick up water. Check water flow at exhaust to make sure all is working as it would if the boat was in the water. |

I did this trick on my Buchanan Midget a couple of years ago after the engine had been sitting for 3 years ( it took me that long to restore the hull). I fed the garden hose into the intake of the water pump - I simply undid the rubber hose to to the thru-hull fitting and connected the garden hose. I too was worried about water getting into the engine, but simply making sure the boat is level should make sure you've got enough slpoe to drain the water out to the exhaust.
I ran it this way for several hours and was able to warm up te oil and engine so that I could get ALL of it out of the engine - I let it drain for 2 days.
I was able to crudely control the temperature of the engine by controlling the flow of water. I found that the engine did not heat up too much because it was not loaded.

I want to start my 3.0L Mercruiser I/O out of the water. I have a pair of 'mouse ears.' I was wondering the correct steps in testing the engine without burning it out of course.
Do I put the ears on, start the water running and try starting the engine?
Thanks

Gentleman be careful when starting inboards on land if the shaft is still connected you could ruin your cutlass bearing. Most older transmissions will creep in forward or reverse and the prop will spin and on a dry bearing it’s the kiss of death. You can stop the prop by blocking it against the strut or using line to tie it to the strut. The best thing is to disconnect the shaft.
These are just my opinions.

I made an adaptor using a plunger an a hose fitting. I leaks enough so the water runs down the shaft into the bearing but be very careful as suggested. Also, the shaft seal also needs to stay wet. |

When running an inboard on land I second what most people have already stated; you should disconnect the propeller shaft, and run a hose to a bucket so that the engine sucks water not a hose forcing water in. Good luck with your Chris Craft! |
