The story begins:
I had a 91 merc 15 hp that was perfect. but it was stolen from my 14 ft alumacraft. It could push the boat up to 24 mph (gps) and started every time.
I recently purchased a 96 Johnson 15 hp that was well cared for but stored for the last year and a half. By all appearances it was very well maintained.
The biggest problem is that the boat starts very difficult after being warmed up. It starts immediately when cold.
Once warm, if shut down it needs to be immediately choked and pulled twice to get a cough and then 3 pulls later it starts without the choke. I've tinkered with the fuel idle mix and the performance with the cups is great. However, in the water it is now worse.
The bit I have read says this could be related to the float valves, can anyone confirm?
Secondly, the merc would push up to 24 mph and this one tops out at 19. It seems like it should have a lot more left. Any suggestions on this? it runs very smooth at WOT.
Thank you for the advice!
