    Hello everyone, I'm starting to toy with the idea of repowering a 1986 Regal empress 200xl. The boat originally had a 190 horse MerCruiser. I would like to go with a 200 horse outboard. I've done some research I have yet to pull the motor out but will soon. I understand the massive reinforcement that needs to take place to the transom. What I don't understand is how to calculate the weight difference and the coinciding moment arm that will change on the boat. when choosing the right bracket size I believe that mostly has to do with clearance issues with the motor not contacting the back of the boat. I have several questions for your expertise one is it worth it? I have yet to do the math to find out the total cost for this project. I am torn between the idea of putting a down payment on a nicer newer boat verses keeping our old trusty sea turd. LOL also if there is anyone interested in Mercruiser parts everything power-related is for sale. I've got lots of new parts on it just couldn't get it to run right contact me if you have any questions about it

    The transom should be OK if it had a sterndrive before. You need to patch the hole properly though. The tough job is to build an outboard well. That involves cutting down the transom and the aft part of the deck.

    Is the outboard well necessary? I've seen pics of conversions with just the positive buoyancy brackets.

    Yes, that is possible but shifts the center of gravity back a lot more. Ultimately, why do you want to convert it? It is an expensive and time consuming project. You can most likely repair what you have for a lot less money and time.
