Hello, first post.
I'm trying to narrow down a boat design for a future build using a Yanmar 1GM 6.5 HP diesel I recently salvaged from a dead sailboat.
I'm looking at a 1907 yawl boat design from Mystic Seaport Museum. The yawl boat plan shows the engine as a Lathrop "Type 6" and gives a serial number #25277. I can't find anything on "Type 6". Am I correct in assuming "Type 6" should read "6 HP"? If so, is the little 6.5 HP Yanmar a fair comparison to the big Lathrop 6 HP? Thank you.

Google: Lathrop Type 6, 6hp. There is an article in the Sept 2001 "gasenginemagazine website about a Lathrop Type 6, 6hp being displayed at the first ever Chesepeake Antique Marine Engine meet. A Calvin Williams from Gloucester VA had one on display. Reportedly from about 1915. No picture though. Perhaps Mystic Seaport Marine Engine archives has information on the engine. Hope this helps.
