Re: MD7a Hand Crank

Here's the crank that fits our MD6A. I believe the engines are very similar.

Re: MD7a Hand Crank

I had an MD7A on my 1979 S2 9.2C. Jeff H. accuratly described the use of the crank. On my boat the cranking shaft was about four feet long, the crank end had about a 14 inch lever with a handle. Think of a wind up sissors jack. And yes it does work. Practice at the dock first.

I have one on my boat. I can't say that I have ever tried to use it! I will try to get down to the boat this weekend and grab it and take some pics.

Re: MD7a Hand Crank

I have hand cranked a Volvo 2 cyl. before. It is surprisingly easy especially if you have two people (one top crank and the other to operate the compression release. Before cranking, you release the compression relief, the one person cranks the engine up to speed, then as that person backs out the handle, the other person flops down the compression release.

As to safety, before you crank check to make sure the handle backs out properly. The way these handles are designed, the handle engages by screwing in half a turn so that when the engine starts the handle disengages. This should work effortlessly. If there is any doubt that the handle is going on and off easily do not try to do this.

Also, if the engine is hard to start, after a try or two, you need to close the cooling water intake so you don't fill the cylinders with water while you are cranking. Then you need to open the intake quickly once the engine starts. Because the problem of filling the cylinders varies with the engine and installation, some people close the intake before any hand-crank attempt.

West Marine sells them - they are yellow, they hang them in the engine aisle.
