I can't answer on your specific model, but my 2str 20HP Yam weighs just shy of 50 kg. I can JUST lift it onto the transom on my own (but wouldn't do that every trip). Its not so much the weight as the awkwardness - two people would manage it OK - but I'd suggest a trolley if moving it more than a few metres on a regular basis.

a 1990 Mariner brochure that I have, it lists a 20hp ( 2 cyl ) 400cc ( 24.4cu.in ) engine as 112lbs/51kg


I will post a copy of a pic from the brochure & u can see if it is the same model ( the hood/decals maybe a wee bit different as the years went on )

thats going to be heavy !
The 20 hp Yam I have just sold was 47 kilos and that was just about manageable.
Get a friend to help you - or a back brace !

i used to carry our mariner 30 by myself, not more than 20 yards or so though, i found it easier to carry on my own than with someone helping, its not the weight that is difficult its the shape and lack of places to lift it with, nice simple reliable engines, should be ideal for your boat

Shane,

Did you get your motor then? I have a mid 80’s vintage Johnson 25hp that weighs right about 115lbs. My SIB lives on a trailer so I don’t often have occasion to remove the motor, but when I do, I always do it myself as I have fount, as others here have mentioned, that it is simply too awkward when someone else is trying to “help”….

On the rare occasion that I have had to transport it any distance by hand, I have found that you can “sling” it with a pair of cargo straps to a stout oar and then two guys can move it about fairly easy if you go slow. Put the oar on your shoulders and the guy in the back can stabilize the motor by holding onto the lower unit so it doesn’t swing around as much when you walk. Not exactly an walk in the park, but it is doable…
