When I start my MD2, I always have to use my decompression handles.
As the inboard engine is in a wooden crate in the centre of the boat, I always need to lift this engine crate.
I would prefer to start only with a key, and not having to lift the crate. And of course without using the decompression handles.
From friends I understood that an MD2B has this kind of starting method.
Does any one know if the starting parts from an MD2B will fit on an MD2? |

I used to start my MD2B in the same way before I discovered the cold start device. In that time I had no manual. With the aid of the dynastart the MD2B now starts immediately (even after winterstop) without lifting decompression levers.
I first put the engine speed control in (allmost) full speed position then press down the cold start button on the cover of the fuel injection pump (that sequence is important otherwise the button doesn't stay in cold start position). Lifting decompression levers is only needed with handstart unless you are very strong. To push down the cold start button I allways have to remove the cover (hatch) of the engine room. A MD2 should have a cold start device as well. According to the manual it's not a button but a rod that has to be pressed down. After starting the cold start device is released automatically. In your case it might be possible to make a simple mechanical device for remote pressing down the cold starting control rod from outside the crate. |

You guys must live in cold weather country. I kept my boat in San Francisco Bay and never had to use the decompression levers or cold start device. If my battery was up the engine would start after a few turns every time about the same as my truck.
If you don't live in cold country I would suspect other problem(s). |

Thanks for the quick responses:
to Adsum; The complete engine is covered under the crate. And as far as I can find there is indeed a fuel rod that brings the fuel into the fuel system quicker than the fuel pomp does. But your idea is not bad, I will give it a try.
To Matt: yes I live in Amsterdam, so mostly between 15 and 25 C degrees when I go out with the boat. |

That's funny, I also live in Amsterdam. But I only use the decompression levers when the hot engine refuses to stop (one of it's bad habbits).
Even in summer with 90 degrees F (32 dgr C) I push the cold start button to achieve an immediate start. |

That sounds like SF Bay temps usually between 15 and 27C during sailing season.
Sounds to me you may have low compression have you checked it recently?
If you kill the engine then restart when it is still hot does it fire up immediately without anything more than turning the key? |

When the engine is nice and warm, a restart with only the keys is no problem. But when it is cold there is too much pressure for the start engine to get the rotations going. |

Using the decomp levers is not a good idea to stop a running engine. I'm surprised you haven't run a valve into the top of a piston causing catastrophic damage.
To stop an engine that doesn't want to, wad up a large rag and place it over the intake. This will also stop a runaway engine. Just be sure to use large rag(s) so they don't get sucked into the engine.
When an engine won't shut down at low throttle and keeps dieseling it is an indication that a decoke job is in order. |

How much does your boat weigh?
The MD2 only makes 15.5hp. and a lot of that would be comsumed in the outdrive. I would think you would get no more than a few knots in dead calm water. I suppose it would be OK on a protected inland waterway but I wouldn't want to use it on a river, large lake, or the ocean. |

You might sell the 2B and put the money toward a bigger diesel. If it is in really great shape I might be interested.
It is going to be a lot of work to do the conversion. |
