Test a diesel on the hard?

[GBurton]

This is a Volvo MD2B ...... do people use some sort of "ear" system to do this?

The cooling is raw water only

[sailortjk1]

Take a standard garden hose, cut off the threaded connector, and use a hose clamp to hook it up to your raw water intake.

Thanks - will do

You can also use a five gallon bucket if a hose won't reach, but watch for the bucket to empty.

Engine cooling may be accomplished as previously described, but don't forget that your cutlass bearing requires water lubrication if the shaft is turning.

NEVER put a pressurized hoose on the water pump!
Put the gardenhose in a bucket and a hose from pump into the bucket and let the pump suck. Pressurizing the water pump, and You run the risk of filling the engine with water through the water pump shaft and seals. This goes for all engines with waterpumps mounted on the engine and driven directly by intermediate or cam-shaft like the volvo's.

haffiman, you beat me to the warning. I made this mistake on a Volvo diesel and filled one cylinder with water through the exhaust valve while the engine was not running. Took me most of a day to get the water out and the engine running again. BTW, if you think you might have put even a little water in the cylinders, DO NOT START THE ENGINE!! Water will not compress, and you will break something. Use the bucket and let the water pump pick the water up the way it is designed.

Ditto on the pressurized garden hose to water intake. Although a common practice with gas motor outdrives and outboards using an "ear muff" attachment, it's not a wise idea with diesels. Service manuals for my Lehman SP 90 warn against using this procedure.

Also, take a moment to check below the wet exhaust through-hull for anything which may get flooded . . . never know if a SL 450 owner decided to park his convertable at your stern.

I can't agree more ALWAYS suck out of a bucket & NEVER put pressurized water to your engines intake!

Put the bucket in the cockpit and run a hose to your sea strainer intake this prevents getting the cabin wet...
