We ran twin Mk-5’s last Monday night on the 14′ Lund. Lots of fun to run twins. These are wonderful running motors, but they have poor sealing lower units. The biggest issue with them is freeze damage to the lower units due to water intrusion. They take some learning to get the hang of them, but once dialed in, they are really nice motors. I may have a carburetor for one also, but am going to be away for some time before I can confirm it. There are usually lots of parts available for them as so many have had lower unit failures so there are a lot that have been parted out.
