Volvo penta MD2

[Sdoss69]

Hi Gang,

We have a 69 Colvic Sea Rover 28ft in Monterey Bay! We have the original inboard - volvo penta MD2 - for which is not running. Bought boat a year ago and the owner informed us engine was not operational - although he recalls getting her to turn over - we currently have 15hp Yamaha for motoring.

Question- we wish to have this engine back up - running and dependable- (outboard is almost useless in reverse) and the mechanic is coming out on Sunday - anything you would suggest we consider for when the mechanic inspects her? I have heard whispers these are great engines and easily repaired - true? Any thoughts on this engine would be warmly welcomed! To our knowledge the inboard has not been used in over 7-10 yrs. so definitely requires some elbow grease?

Also what are typical ranges of pricing for full engine overhaul for this type of motor - anyone know?

Thanks so much - we are new all the way and welcome the wisdom!

Many years ago, I had an MD2B that failed. My Volvo expert suggested that instead of fixing it, that I should replace it with an MD11C. It's externally identical but (if I remember right) has sleeved cylinders, factory installed fresh-water cooling and a better hand-starting system.

Thanks for your response! I wondered what might be the differences between the MD2 and MD2B and a possible upgrade as you mentioned? The mechanic seemed quite optimistic about repairs and we are able to get the engine to turn which is promising. Thanks for the suggestion!

Sorry, but I don't remember the differences between the MD2 and the MD2B. But if you need information on Volvo, check with Darryl at Eskelund Marine in Alameda. He worked on my Volvos from 1976 until I sold that boat in 1999. He only works on Volvo motors and he knows them completely.

The MD2 has 14, or maybe 15 HP, and the MD2B has 25 HP. The MD2 has a starter/generator, and the 2B has a conventional starter. The starter/generator is very expensive to overhaul, and doesnt put out much charge. I assume the displacement of the 2B is larger, since it is a pretty big jump in HP. I tried to call Eskelund Marine today and the number I got off of the web was not valid.(510-523-7670} If anyone has a current phone number for him, I would appreciate it.____Thanks____Grant.

I helped my friend with the MD2 again today, and ran across the spec sheet. It shows 16.5 HP. It has 54.3 cubic inch displacement. I did learn from a dealer that the MD2 tranny will bolt right up to an MD11. Just a few tid bits to share.______Grant.
