I hope someone can help me here
The boat starts perfect but has a significant miss at idle.
When I try to let it warm up she stalls out.
When a friend revs it up from the back when I start it I can hit snap it in gear and she will run smooth as a kitten until I shut her off and it all starts over again.
I am thinking carb problem but not sure.
I cannot see an airleak in a hose but they can be impossible to find anyways.
I also cannot find any set screws on the carb itslef.
If someone has some ideas it would be appreciated.
 
Compression/spark test?
Clean the carb.Make sure the jets are clear.
The air screw front top of carb(you have one?)in till it just bottoms out.
Then out 1 and 1/16 turn.Then adjust from there.
Pic of the carb?Front and sides.J
 
Check and replace the crankshaft seals. Most common is the top seal wears out and then starts drawing air in that leans the mixture. On a motor this old, it's a good possibility.
