For info, the Suzuki DF15 4-stroke short shaft is 44kg. I owned one of these with a Suzumar 360. It is virtually the same as the Honwave 3.5, apart from the tube cones, hence the extra 10cm.
The two were a perfect match but even with the relatively lighter weight, the motor wasn't exactly portable. Getting it from the garage to the car was okay, but much further was a struggle.
Just a suggestion:if you go down the route of carrying rather than trailering, inflate the boat as near to your car as possible, mount the motor and use transom wheels to get to your launch site.
I have owned the Suzumar 360 with Suzuki 15, a Honwave 3.8 with Honda 20 and a Lodestar 320 with Yamaha 8, and ended up trailering all of them.
Hope this helps rather than adding to the confusion!
Happy when wet!
