Terrydi Topic Author Offline Gold Boarder Posts: 780 Karma: 60 Thank you received: 72	Hey All, Working with a buddy to select a correct motor for this 1952-53 11’ Thompson Speed Demon. He is a Johnson guy but got him convinced to go Merc. I found a 1955 Mark 20 but I think he will need a short shaft. Any ideas or suggestions would be appreciated. Thanks, Terry Attachments: Check this box to be notified of replies to this topic. Note: BBcode and smileys are still usable.

That is a racing bo at. the block was added for a short shaft service motor. 10ft was a B classMark 20H 11ft would be a C class. Mark 30H Attachments: Check this box to be notified of replies to this topic. Note: BBcode and smileys are still usable.
