I don't want to get into a war over this, but I believe the original question was "whats wrong with MDS" not whats right with OS. I know OS is a great engine I even own one. But it is by far not my best engine. I own a OS 46 FX and it is very reliable and runs great. But I also own MDS, Magnum and Tiger Shark engines. I have had to work on all of these engines at one time or another so asking a question on whats wrong with MDS makes good since to a person who is thinking about trying another engine. Do not be afraid of trying something different. I didn't and found out my Tiger Shark 46 & 52 are every bit as good as an OS and at 2/3 of the cost.

Have a ball with your MDS if you decide to go that direction.

Thanks
